Overview

Progress in US-Iran negotiations has generated significant cross-asset volatility as of late May 2026, with the prospect of reopening the Strait of Hormuz driving a sharp repricing of crude oil benchmarks, equity indices, and sovereign bond markets. On May 24, 2026, President Donald Trump confirmed that a framework agreement had been "largely negotiated," and US Secretary of State Marco Rubio signaled "some good news" could emerge within hours regarding the strait [1][7]. The potential deal — brokered primarily by Pakistan — centers on a phased memorandum of understanding under which Iran would reopen the Strait of Hormuz and dispose of its highly enriched uranium in exchange for an end to the US naval blockade and the unfreezing of certain Iranian assets [1][8]. However, critical details remain unresolved, including the mechanism for uranium disposal, the status of Iran's ballistic missile program, and Iran's demand for formalized influence over strait transit [2][7]. The following report analyzes how global oil prices, equity markets, and fixed-income instruments have reacted to these developments, quantifying the immediate impacts and evaluating the short- and long-term economic implications for inflation and central bank policy.

1. US-Iran Negotiations and the Status of the Strait of Hormuz

1.1 The Conflict and the Blockade

The US-Israeli military campaign against Iran, launched on February 28, 2026, triggered the effective closure of the Strait of Hormuz — a 33-kilometer-wide waterway through which approximately one-fifth of global oil and LNG shipments transited before the war [3][22]. Iran retaliated against the initial strikes by threatening and attacking commercial vessels, while the US Navy imposed a parallel blockade on Iranian ports beginning April 13, redirecting over 85 commercial vessels [5][22]. By late April, traffic through the strait had fallen from a pre-war average of 129 vessels per day to as few as eight, and Goldman Sachs estimated that exports through the chokepoint had dropped to just 4% of normal levels [4][22].

1.2 The Negotiation Timeline Preceding the May 24 Breakthrough

Diplomatic efforts accelerated in late April after Iran offered to reopen the strait in exchange for deferring nuclear talks, a proposal President Trump initially rejected on April 27 [6]. A fragile ceasefire agreed on April 8 faced repeated tests, most notably on May 4 when the US launched "Project Freedom" to guide commercial vessels through the strait, prompting Iran to warn that any foreign military force approaching the waterway would be targeted [3]. Throughout May, negotiations followed a volatile pattern: Iran submitted a counterproposal found "insufficient" by US officials on May 8, President Trump canceled a planned military strike on May 18 at the request of Gulf allies, and Iran established the Persian Gulf Strait Authority (PGSA) to formalize its claim over transit coordination [5][9]. By May 22, both sides acknowledged "narrowing differences," and on May 23, Trump announced that a framework had been largely negotiated, including the reopening of the Strait of Hormuz [1][7].

1.3 The May 24 In-Principle Agreement

On May 24, 2026, a senior US official confirmed that the United States and Iran had agreed in principle to reopen the Strait of Hormuz, with Iran committing to dispose of its highly enriched uranium [2][7]. The agreement is structured as a two-phase memorandum of understanding. In Phase 1, Iran would restore strait transit to pre-war levels and provide assurances against pursuing nuclear weapons, while the US would lift its naval blockade and unfreeze some Iranian assets. Phase 2, spanning 30 to 60 days, would address detailed negotiations over Iran's nuclear program, including its stockpile of near-weapons-grade uranium estimated at over 440 kilograms of 60% enriched material [1][8]. Crucially, the agreement defers several contentious issues: Iran's missile stockpile is not addressed, no moratorium on enrichment is stipulated beyond the uranium disposal commitment, and Iran's state-affiliated Fars News has disputed the characterization of "free passage," insisting that the strait would remain under Iranian oversight [2][7]. Iran has also sought Omani support for a formalized toll system — with proposed fees of $150,000 to $2 million per vessel — a proposal that the US and Greece have rejected and that the International Maritime Organization has declared inconsistent with international law [8][9]. The deal now requires final approval from President Trump and Iran's Supreme Leader Mojtaba Khamenei, a process that could take several days [2].

1.4 Implementation Challenges

Even under the most optimistic scenario, logistical normalization will take considerable time. Saudi Aramco CEO Amin Nasser warned on May 11 that "even if the strait were to reopen today, it would take months for the market to rebalance," noting that the disruption has removed approximately 100 million barrels per week from global supply and that only 2-5 vessels were crossing the strait daily compared to roughly 70 in normal times [10]. Baker Hughes CFO Ahmed Moghal stated on April 24 that the company's financial guidance assumes the strait may not fully reopen until the second half of 2026 [11]. The Dallas Fed survey of nearly 100 oil and gas executives found that nearly 80% expected the strait to reopen no sooner than August 2026, and over 80% viewed future disruptions as likely [11]. Equinor's CFO added on May 6 that while oil markets could normalize within half a year of reopening, gas markets would take significantly longer [34]. The EIA's May 12 Short-Term Energy Outlook assumed the strait would remain largely closed through late May, with traffic gradually resuming in June and returning toward pre-conflict levels later in 2026 [12].

2. Crude Oil Price Response

2.1 Price Trajectory from Pre-War to the May 24 Deal

Crude oil benchmarks experienced one of the most severe supply-driven price surges in modern history following the February 28 outbreak of hostilities. Brent crude, which traded at approximately $72 per barrel before the war, rose to a peak of $138 per barrel in April, averaging $117 for the month [12][13]. West Texas Intermediate followed a similar trajectory, surging from approximately $68 to a war high above $110 [13]. By April 30, with negotiations stalled and the strait effectively closed, Brent breached $125 per barrel and WTI traded at $107.09 [4].

The subsequent weeks saw extreme headline-driven volatility. On May 6, after Trump hinted that the strait could become "OPEN TO ALL," Brent fell 7.8% to $101.27 and WTI dropped 8.4% to $93.67 — the largest single-day declines since the war began [14]. Prices rebounded on May 11 after Trump declared the ceasefire on "life support" and rejected Iran's latest offer, with Brent settling at $104.21 [15]. Throughout the week of May 18, Brent fluctuated between $107 and $112 as Trump simultaneously threatened renewed bombing and called off a planned military strike [9][16]. By May 21, physical crude prices had eased to the $100-$110 range, driven by demand destruction in China and record US exports [17].

2.2 The May 24 Price Collapse

On Sunday, May 24, crude oil prices dropped sharply in Asian and Middle East trading as news of the in-principle deal circulated. Brent crude futures fell $4.64 (4.48%) to $98.90 per barrel, while WTI dropped $4.42 (4.58%) to $92.18 [18]. This brought Brent below the psychologically significant $100 threshold for the first time since early May. The magnitude of the decline reflected both relief that a diplomatic resolution appeared imminent and the market's recognition that the deal structure — including the 30-60 day implementation period and unresolved uranium disposal mechanism — meant that physical supply would not return immediately [2][7]. Saxo Bank analyst Ole Hansen noted that prices had remained at "relatively subdued levels, despite what is arguably the largest supply disruption in modern history," indicating that demand destruction was proving more widespread than initially expected [17].

2.3 Supply-Demand Dynamics Beneath the Price Surface

The price action masks extraordinary dislocations in physical markets. The IEA reported on May 14 that observed global inventories had been drawn down by 250 million barrels over March and April — a rate of 4 million barrels per day — and that cumulative supply losses from Gulf producers had exceeded 1 billion barrels, with more than 14 million barrels per day of oil shut in [19]. Global oil supply fell by 1.8 million barrels per day in April to 95.1 million barrels per day, with total losses since February reaching 12.8 million barrels per day [19]. OPEC+ responded with three consecutive monthly output increases totaling 188,000 barrels per day for June, but these were characterized as largely symbolic given that the Strait's closure had severely constrained the ability of key members like Saudi Arabia, Iraq, and Kuwait to actually export additional volumes [20][21]. Iraq's oil ministry revealed that the country exported only 10 million barrels through the strait in April, down from approximately 93 million barrels per month before the war [22].

On the demand side, China slashed net seaborne crude imports by 5.5 million barrels per day year-on-year in the 30 days to May 8, and refining runs dropped nearly a fifth from pre-war levels [17]. The US government sold 133 million barrels from the Strategic Petroleum Reserve, and US crude and fuel exports rose to 13 million barrels per day in early May compared to 11.2 million in March [17]. JPMorgan revised its 2026 Brent average forecast to $96 per barrel, with quarterly averages of $103 (Q2), $104 (Q3), and $98 (Q4), and projected that even with a June reopening, inventories could reach stress levels by August due to summer demand [23]. Barclays raised its forecast to $100 per barrel from $85, warning that if disruptions persisted through the end of May, prices could reprice toward $110 [24].

3. Energy Sector Stock Performance

3.1 Major Integrated Oil Companies

First-quarter 2026 earnings for the supermajors revealed a paradox: surging crude prices failed to translate into proportionally higher reported profits due to losses on hedging positions taken before the war. Exxon Mobil reported net income of $4.2 billion, a 45% decline from $7.7 billion a year earlier, despite revenue of $85.14 billion that beat Wall Street estimates [25]. The company incurred nearly $4 billion in losses on open hedges plus $700 million on closed hedges. CEO Darren Woods described the impact as temporary, noting that physical barrels remained in inventory and would generate profits once delivered [26]. Excluding timing effects and Middle East volume impacts, Exxon reported underlying earnings of $8.8 billion, with upstream earnings of $5.7 billion and net production of 4.6 million oil-equivalent barrels per day [27].

Chevron reported net income of $2.2 billion, a 36% decline from approximately $3.5 billion a year earlier, driven by a $2.9 billion hedge-related charge [25]. Revenue of $48.61 billion beat expectations, and CEO Mike Wirth warned that "the global energy system continues to be under extreme stress" and that physical shortages would begin to emerge, likely hitting Asian markets first [28]. On May 12, Wirth stated that "demand needs to move to meet supply" and that "economies are going to have to slow," noting that global oil inventories had fallen to an eight-year low of approximately 101 days of expected demand and were on pace to reach 98 days by the end of May [28]. Refined products stockpiles — gasoline, jet fuel, and diesel — were even tighter at roughly 45 days of demand, approaching critically low levels [28].

3.2 Refiners, Traders, and Shipping

BP posted its highest quarterly profit since 2023, crediting "exceptional oil trading" for the results, a development that prompted renewed calls for windfall profit taxes in Europe [26]. Occidental Petroleum saw bullish options activity ahead of its May 5 earnings report, with call volumes outpacing puts seven-to-one, and the stock rallied 42% year-to-date compared to a 30% gain in the Energy Select Sector SPDR ETF (XLE) [29]. The XLE was up approximately 30% year-to-date as of early May [29].

The most dramatic performance came from the Breakwave Tanker Shipping ETF (BWET), a little-known $30 million fund launched in May 2023, which surged over 600% year-to-date amid the disruption to maritime corridors. ETF experts noted that the rally reflected investor focus on energy infrastructure and shipping costs rather than just oil prices, with BWET up over 1,000% in the past year [30].

3.3 Downstream and Petrochemical Pressures

The ICIS global petrochemical index (IPEX) recorded a 50% jump in prices, with regional impacts varying: Asia up 57%, the US Gulf up 43%, and Northwest Europe up 35% from already elevated levels following Russia's invasion of Ukraine [31]. Dow Chemical CEO Jim Fitterling stated that even if the strait reopened immediately, clearing the logistics logjam would take 275 days or more [31]. Fertilizer maker Mosaic cut output and withdrew its phosphate production guidance for 2026 after the war raised input costs, and the company's stock fell 1.8% in one session due to higher sulfur and raw material costs from war-related logistics snarls [32]. The World Bank projected that fertilizer prices would rise 31% in 2026, with urea rising 60%, amplifying food price pressures globally [33].

4. S&P 500 and Broader Equity Markets

4.1 A Market Decoupled from Oil

One of the most striking features of the current market environment is the decoupling between elevated crude prices and the S&P 500, which repeatedly set all-time highs throughout May 2026 even as Brent traded above $100 per barrel. The S&P 500 closed at a record 7,365.12 on May 7, rose to 7,412.84 on May 11, and reached 7,445.72 by May 22 — all while oil prices remained highly elevated [14][15][34]. The Dow Jones Industrial Average closed above 50,000 for the first time since February on May 14, and the Nasdaq Composite also hit multiple records during the period [35][36].

This decoupling was driven overwhelmingly by technology and AI-related earnings. First-quarter S&P 500 earnings were on track to climb almost 29% year over year, with much of that growth concentrated in a handful of mega-cap technology companies [15]. UBS Global Wealth Management raised its year-end 2026 S&P 500 target to 7,900 from 7,500, citing resilient consumer spending and strong demand for data center infrastructure, while warning that the lack of resolution around the Strait of Hormuz could begin to undermine these bullish drivers if oil prices and interest rates continued to rise [37]. SocGen estimated that semiconductors alone had added approximately $2.2 trillion in market capitalization, accounting for 84% of total S&P 500 gains, and were responsible for roughly 75% of US tech earnings-per-share growth [38].

4.2 Sector-Level Differentiation

The oil price shock did exert significant pressure on specific sectors. Fuel-sensitive stocks underperformed: Southwest Airlines declined 3.2% on May 11, Royal Caribbean fell 4.3%, and Delta Air Lines lost 2.2% due to higher jet fuel costs [15]. Home Depot shares fell 2.2% after its quarterly results, with same-store sales growth disappointing as consumer spending shifted toward energy [39]. Dollar General dropped 7.6%, reflecting the disproportionate impact of higher gasoline and food prices on lower-income households [15]. The Russell 2000 index of small-cap stocks fell 2.07% on May 15 alone, more than double the decline in the S&P 500, as smaller companies faced tighter margins from higher energy costs [40].

4.3 Sensitivity to Headline Risk

Despite the overall upward trend, the S&P 500 remained sensitive to oil-driven volatility on specific days. The Dow shed 550 points on May 4 after the US launched Project Freedom and Iran called it a ceasefire violation [41]. On May 15, stocks fell sharply — the Dow dropping over 400 points and the S&P 500 falling 0.73% — after Brent surged 3% to $109 following Trump's statement that the US "doesn't need the waterway open" [40]. The 10-year Treasury yield jumped above 4.57% that day, compounding equity pressure [40]. The S&P 500 then fell for three consecutive sessions from May 17-19 as oil remained volatile and the 10-year yield climbed to 4.66% [39][42]. However, each selloff was followed by a recovery as AI-related earnings momentum reasserted itself, and the S&P 500 posted eight consecutive weeks of gains through May 22 [34].

4.4 International Equity Divergence

The Nikkei 225 showed a much stronger inverse correlation with oil prices and Hormuz headlines than the S&P 500, consistent with Japan's near-total dependence on Middle East oil imports. On May 7, the Nikkei surged over 5% to close above 62,000 for the first time, even as tensions remained elevated, because Trump simultaneously signaled potential de-escalation if an agreement was reached [43]. On May 24, the Nikkei jumped 3.1% to 65,321.56 in morning trading following the in-principle deal announcement, significantly outperforming US futures [18]. By contrast, on May 15 — when oil spiked and Trump questioned the need for the strait — the Nikkei slumped, South Korea's Kospi fell more than 6%, and Japan's 10-year government bond yield settled at its highest level since 1997 [40][44].

5. Global Inflation Dynamics

5.1 Direct Energy Price Pass-Through

The conflict has driven energy prices to levels not seen since the 2022 Russia-Ukraine crisis and, in some metrics, beyond. US gasoline prices averaged $4.55 per gallon by May 22, up more than 50% since the war began, while diesel averaged $5.65 per gallon [9][45]. The World Bank projected energy prices would rise 24% in 2026, the highest since 2022, with knock-on effects increasing natural gas prices by 7% [33]. US CPI inflation accelerated from 2.4% in February (pre-war) to 3.3% in March and reached 3.8% in April, while core CPI stood at 2.8% [46][47]. The PCE inflation measure, the Fed's preferred gauge, reached 3.5% as of March [48].

5.2 Second-Round Effects and Inflation Expectations

A growing body of evidence suggests that the energy shock is beginning to spill over into broader price-setting behavior. The University of Michigan's May survey released on May 23 showed year-ahead inflation expectations rising to 4.8% from 4.7%, while long-run expectations surged to 3.9% — well above the 2.8% to 3.2% range that prevailed throughout 2024 [49]. Surveys of Consumers Director Joanne Hsu noted that consumers "appear worried that inflation will increase and proliferate beyond fuel prices, even in the long run" [49]. The ICIS global petrochemical index recorded a 50% jump since the war began, with polymer prices rising 20-30% per month since March and paracetamol raw material costs increasing 400% [31].

5.3 Demand Destruction as an Inflation Mitigant

The primary force preventing even more severe inflation has been demand destruction — or, as Saudi Aramco CEO Nasser termed it, "demand rationing" [10]. China's crude imports fell approximately 25%, from 11.7 million barrels per day before the war to 8.2 million barrels per day, a swing nearly equal to Japan's total consumption [17]. Chinese refiners slashed production by nearly a fifth. The IEA projected that global oil demand would fall by 2.4 million barrels per day year-on-year in the second quarter of 2026 and that refinery crude throughputs would plunge by 4.5 million barrels per day [19]. The IEA warned that "a weaker economic environment and demand-saving measures will increasingly impact fuel use" [19]. This demand compression has been the key factor preventing Brent from sustaining levels above $125, even as physical supply has been cut by over 14 million barrels per day.

6. Bond Markets and Yield Response

6.1 US Treasury Yield Surge

The combination of elevated oil prices, rising inflation expectations, and massive fiscal deficits has driven one of the most aggressive repricings in US Treasury markets since the 2008 financial crisis. The 10-year yield rose from approximately 4.37% on April 28 to 4.568% on May 15 (its highest since May 2025), 4.631% on May 18 (the highest since February 2025), and approached 4.66% on May 19 before retreating to approximately 4.55% by May 22 [40][42][45][50]. The 30-year yield reached 5.112% on May 15, surpassed 5.16% on May 18, briefly touched nearly 5.2% on May 19 — a 19-year high — and stood at 5.086% on May 22 [42][45][50].

A critical signal came on May 13, when the Treasury sold $25 billion of 30-year bonds at a 5% yield, the first time since 2007 that a 30-year bond carried a rate above 4.75%. This marked a sharp reversal from February 2026, when a 30-year auction had seen record demand. Auctions of 3- and 10-year Treasuries also drew less demand than expected [51]. Higher yields are boosting annual interest costs to $1 trillion, worsening the budget deficit [51].

6.2 Real Yields versus Inflation Breakevens

Bloomberg reported on May 24 that bond strategists warned yields would stay elevated even if the Iran war ended, noting that "real yields, which strip out inflation, have had a greater impact, indicating bond investors aren't just worried about price pressures from the Iran war" [52]. Other drivers include soaring fiscal deficits, reduced foreign demand, and structural supply-shock volatility [52]. Peter Boockvar, CIO of One Point BFG Wealth Partners, stated that "long-end rates are now in control of monetary policy" [51].

6.3 Global Bond Market Contagion

The US selloff transmitted aggressively to other major sovereign bond markets. The 10-year UK gilt yield hit 5.19% on May 18, surpassing an 18-year high, and the average two-year fixed mortgage rate in the UK rose to a peak of 5.90% [53][54]. Japan's 10-year government bond yield reached 2.496% on April 13 — the highest since 1997 — and later rose to 2.750% before retreating on deal optimism [55][56]. The 10-year German Bund yield moved in sympathy with US and UK bonds [57]. Mizuho Bank recommended shorting UK gilts and rates, citing the UK's high exposure to the inflation shock and expectations that the Bank of England could become more aggressive [58].

7. Central Bank Monetary Policy Implications

7.1 Federal Reserve: A Deeply Divided Committee

The April 29 FOMC meeting was the most divided since 1992. The committee voted to hold the federal funds rate at 3.50%-3.75% and maintained language favoring a future cut, but three dissenting presidents — Neel Kashkari of Minneapolis and the presidents of Cleveland and Dallas — objected to signaling any bias toward easing, arguing that the oil price shock required the Fed to acknowledge that a rate increase was possible [48][59]. Kashkari stated on May 3: "I don't feel comfortable signaling that a rate cut is in the cards. You know, we might be in worse scenarios, we might have to go the other direction" [48].

New Fed Chair Kevin Warsh was sworn in on May 22, replacing Jerome Powell, whose term concluded on April 29 [60]. An inflation hawk from his 2006-2011 tenure on the Board, Warsh has not commented publicly since April data, but traders are closely watching how he will respond to rising inflation — a dynamic that undercuts President Trump's stated preference for lower rates [61]. DRW Trading strategist Lou Brien commented: "Especially if crude oil stays high, they're going to want to see that Warsh is his own man rather than the president's man at the Fed" [61].

Fed Governor Chris Waller stated on May 23 that he is now more concerned about inflation than the labor market, which has stabilized, and warned that a series of price shocks could "unanchor consumer psychology" [49]. Waller said: "If I believe inflation expectations start to become unanchored, I would not hesitate to support an increase in the target range for the federal funds rate. But at this point that action is premature. It is time to simply sit and watch how the conflict and the data evolve" [49].

Boston Fed President Susan Collins stated on May 15: "More than five years of above-target inflation has reduced my patience for 'looking through' another supply shock," adding that she could envision a scenario where "some policy tightening is needed to ensure inflation returns durably to 2%" [46].

7.2 Market Pricing of Rate Hikes

The federal funds futures market has completely priced out any Fed rate cuts for 2026 and is now pricing in material rate hike risk. As of May 19, fed funds futures showed approximately 50% odds of a rate increase by December 2026 and 73% odds by July 2027 [61]. Forbes reported on May 20 that fixed-income markets expected the FOMC to raise rates from 3.50%-3.75% to 3.75%-4.00% by year-end, with a hike more likely at the December meeting [47]. Barclays reversed its prior expectation of a September 2026 cut and now expects no cuts in 2026, with a quarter-point reduction in March 2027 [62].

However, some strategists caution that the market signal may be overstated. FHN Financial macro strategist Will Compernolle noted: "There's really low trading volumes in the contracts for the middle of next year. I consider it a pretty low conviction signal from the market. The market might just be really hedging for the risk that a hike does eventually come" [61].

7.3 Bank of England

The BOE voted 8-1 to hold rates at 3.75% on April 30, with Chief Economist Huw Pill dissenting in favor of a 25-basis-point increase [63]. The BOE warned that inflation is likely to rise further later in 2026 as higher energy costs pass through and noted risks of "material second-round effects" [63]. UK CPI accelerated to 3.3% in March, up from 3% in February, driven by higher fuel prices [64]. The IMF advised the BOE on May 18 that it does not need to hike and should be prepared to cut if necessary, projecting that holding rates for the remainder of the year would be sufficient to bring inflation back to target by end-2027 [65].

7.4 Bank of Japan

The BOJ voted 6-3 to hold the policy rate at 0.75% on April 28 but dramatically revised its forecasts: core inflation for fiscal year 2026 was raised to 2.8% from 1.9% — a 0.9 percentage point increase — while the growth forecast was cut to 0.5% from 1% [55]. The BOJ warned that the Middle East crisis would crimp corporate profits and real household incomes "through factors such as a deterioration in the terms of trade" [55]. Japan introduced gasoline tax cuts and subsidies to cushion the impact, and the yen weakened to 159.05 per dollar, near intervention territory [66].

7.5 European Central Bank

The ECB held rates steady at its April 30 meeting and offered no specific forward guidance on Iran-related impacts, remaining in a holding pattern alongside other major central banks [67].

8. Outlook and Implications

8.1 Short-Term Market Trajectory

The immediate market reaction to the May 24 in-principle deal — Brent falling 4.5% to $98.90 and WTI dropping 4.6% to $92.18 — reflects relief that a diplomatic resolution is within reach, but the price decline was contained by the reality that implementation will take weeks or months [18]. S&P 500 futures pointed to further gains, and the Nikkei's 3.1% surge indicated that Asian markets, most exposed to Middle East supply, were pricing in the most optimistic scenario [18]. Bond markets remained cautious, with yields still elevated despite the deal optimism, as investors priced in the risk that inflation expectations may have become durably unanchored [49][52].

8.2 Medium-Term Risks and Uncertainties

Several factors could disrupt the current trajectory. First, the deal requires final approval from both President Trump and Iran's Supreme Leader — a process that could fail or produce last-minute demands that unravel the framework [2][7]. Second, even if approved, Iran's insistence on formalized toll authority and its claim that "free passage" is not guaranteed create a structural risk that the strait will not return to pre-war operating norms [2][8]. Third, the IEA and Saudi Aramco have warned that rebuilding supply chains, clearing mines, and restoring production could extend well into 2027 [10][11][19]. Fourth, the damage to oil infrastructure — including potential damage to Saudi and UAE facilities — may limit production capacity beyond 2026, creating "more persistent price pressures and deeper economic disruptions" according to S&P Global Ratings [45].

8.3 Long-Term Structural Implications

The US-Iran conflict and the Strait of Hormuz closure have fundamentally altered the global energy landscape. The war demonstrated the extreme vulnerability of the world's most critical energy chokepoint and has accelerated efforts to diversify supply routes, expand pipeline capacity (such as Saudi Aramco's East-West pipeline to Yanbu), and build strategic reserves [10][12]. The UAE's formal departure from OPEC on May 1, combined with the fracturing of the OPEC+ alliance, suggests a lasting reorganization of producer coordination [20][68]. The Dallas Fed survey's finding that over 80% of executives expect future disruptions indicates that geopolitical risk premiums will remain embedded in oil and LNG prices for years [11].

For central banks, the key challenge is distinguishing between a transitory supply shock and a structural shift in inflation dynamics. Treasury Secretary Scott Bessent has argued that "nothing is more transient than a supply shock" and predicted a flood of supply within six to nine months [69]. Bond markets, through elevated term premiums and rising real yields, are signaling that they see a higher probability of persistent inflation. The University of Michigan survey's surge in long-run expectations to 3.9% — the highest in decades — suggests that consumer psychology may have begun to shift in ways that could make the current inflation episode self-reinforcing [49]. The resolution of this tension between the Treasury view and the bond market view will determine whether the Federal Reserve can avoid rate hikes in 2026 or whether the combination of unanchored expectations, tight labor markets, and fiscal dominance forces a tightening cycle that would have profound implications for growth, employment, and asset prices globally.

8.4 Scenario Analysis

Under the most constructive scenario — rapid final approval of the May 24 framework, strait reopening within weeks, and no significant infrastructure damage — Brent could settle in the $85-$95 range by the fourth quarter of 2026, consistent with JPMorgan's base case of a $96 full-year average [23]. This would ease inflation pressures, allow the Fed to hold rates steady, and support continued equity gains driven by AI and technology earnings. Under a delayed or partial implementation scenario — where the strait reopens but Iran maintains de facto control through fees and coordination requirements, and production restoration takes six months or more — Brent would likely remain in the $100-$110 range through year-end, perpetuating the current tension between strong corporate earnings and rising inflation expectations. Under a worst-case scenario — deal collapse, renewed hostilities, and prolonged strait closure — ANZ analysts have warned that Brent could surge toward $200 per barrel, triggering global recession, widespread demand rationing, and forced monetary tightening across developed and emerging economies alike [3].
