Revision #1

On February 28, 2026, the United States and Israel launched coordinated airstrikes on Iran in what the Pentagon dubbed "Operation Epic Fury." Within hours, Iran's Islamic Revolutionary Guard Corps broadcast warnings over VHF radio: no ships would be permitted to pass through the Strait of Hormuz [1]. The narrow waterway — just 21 miles wide at its tightest point — carries roughly 20 million barrels of oil per day, approximately 20% of global seaborne oil trade [2]. Five days later, the strait is effectively closed, and the consequences are reverberating through every corner of the global economy.

This is no longer a regional military conflict. It is an economic event with the potential to reshape global markets for months, if not years, to come.

The Chokepoint Goes Dark

The Strait of Hormuz has long been recognized as the single most critical bottleneck in the global energy supply chain. Saudi Arabia, the United Arab Emirates, Iraq, Kuwait, and Qatar all depend on it to export their hydrocarbons to the world. The U.S. Energy Information Administration has repeatedly flagged it as the world's most important oil chokepoint [3].

What has unfolded since February 28 is not a traditional naval blockade. Iran has not physically sealed the strait with warships. Instead, a combination of IRGC warnings, drone strikes on Qatari LNG facilities at Ras Laffan and Mesaieed Industrial City, and attacks on at least four vessels transiting Gulf waters have created what analysts are calling an "insurance blockade" [4]. Tanker traffic dropped by approximately 70% within the first 48 hours. Over 150 ships anchored outside the strait, waiting. By day three, transit had fallen to effectively zero [1].

The cost of moving crude has exploded in response. Supertanker rates for routes from the Middle East to China surged more than 94%, hitting an all-time record of $423,736 per day [5]. With insurers withdrawing war risk protection for vessels transiting the region, the economic logic of attempting passage has collapsed even without a single Iranian warship blocking the lane.

Qatar, one of the world's largest exporters of liquefied natural gas, was forced to halt production after Iranian drones struck its processing facilities [1]. The ripple effects of that single attack are being felt from Tokyo to Berlin.

Oil Markets in Turmoil

The immediate market response was dramatic but, according to some analysts, surprisingly contained — at least so far. Brent crude spiked 13% at the Monday open, briefly touching $82 per barrel [6]. West Texas Intermediate crude climbed more than 4% to $74 per barrel [7]. By midweek, Brent had risen 36% year-to-date, while WTI futures were up 32% [8].

Those numbers tell a story of a market that is alarmed but not yet panicked. NPR reported that while prices have surged, "there's no panic yet" — a reflection of several mitigating factors including robust U.S. domestic production, which has made America the world's largest oil producer, and significant global inventories built up during a period of relatively soft demand [9].

But the calm may be fragile. Goldman Sachs' head of oil research told Fortune that current market pricing implies traders are betting the disruption will last approximately four weeks [10]. If it extends beyond that — or if hostilities escalate further — the calculus changes dramatically. Oxford Economics has modeled a scenario in which Brent could push toward $100 per barrel, a level that would trigger cascading economic consequences [11]. S&P Global Ratings estimates oil supply is disrupted by an average of 4 million barrels per day over the next quarter, with Brent expected to average $79 in Q2 — $15 above baseline — before easing as supply potentially resumes by quarter's end [12].

Stock Markets: A Tale of Winners and Losers

The conflict has cleaved equity markets into clear winners and losers. On March 3, the S&P 500 fell 0.95%, the Nasdaq lost 1.02%, and the Dow slid 0.83% as oil-driven inflation fears gripped investors [7]. Energy-sensitive sectors like airlines and travel were hammered as soaring jet-fuel costs and Middle East route disruptions weighed on sentiment [13].

But for energy and defense companies, the crisis has been a windfall. Exxon Mobil jumped 4.7% to an intraday record [6]. Norwegian oil and gas exporters Vår Energi and Equinor led Europe's Stoxx 600, each gaining more than 9% [14]. Defense contractors surged as well: Northrop Grumman rose 6%, RTX Corporation climbed 4.7%, and Lockheed Martin added 3.37% [15]. The iShares US Aerospace & Defense ETF has now gained 14% in 2026, with the rally accelerating sharply since hostilities began.

Bloomberg reported that Wall Street has shifted to a "haven-first" strategy, with institutional investors reallocating toward energy, defense, and safe-haven assets while reducing exposure to growth and consumer discretionary names [16]. The pivot reflects a market bracing for a prolonged disruption rather than a brief flare-up.

Gold's Historic Run

Perhaps no asset tells the story of this crisis more clearly than gold. Prices surged past $5,300 per ounce for the first time in history on the day of the strikes, with futures jumping more than 2% in a single session [17]. By early March, gold had tested $5,400 — a level that would have seemed fantastical just a year ago [18].

The rally is being driven by a confluence of factors beyond the immediate conflict: central bank buying, currency debasement fears, and a broader flight from risk. Gold has gained approximately 22% year-to-date [19]. JPMorgan has forecast prices could reach $6,300 per ounce by year-end if demand from central banks and investors continues at its current pace [19]. Analysts at several firms have set near-term targets of $5,500 to $6,000 should hostilities intensify further [19].

The Inflation Specter Returns

For central bankers, the timing could hardly be worse. Just weeks before the strikes, the Trump administration had declared inflation "tamed" [20]. Now, a supply-driven energy shock threatens to undo months of disinflationary progress.

The math is sobering. CNBC reported that every $10 increase in oil prices translates to roughly a 0.2 percentage point rise in inflation and a 0.1 percentage point drag on economic growth [8]. With Brent already up significantly and gasoline prices spiking, those fractions add up quickly.

American consumers are already feeling the pinch. The national average price of unleaded gasoline hit $3.11 per gallon on Tuesday — up 20 cents in just a few days, a 7% increase [21]. Analysts expect the national average to reach $3.25 to $3.50 in the coming weeks if disruptions persist [22]. Axios reported it was the biggest single-day gas price spike in three years [21]. The impact falls disproportionately on lower-income households, who spend a larger share of their budgets on fuel and are already under considerable financial pressure [22].

But the inflationary pressure extends well beyond the gas pump. Trucking companies are beginning to add fuel surcharges, which will ripple through consumer goods delivery costs. Supply chain rerouting, higher insurance premiums, and disrupted shipping schedules all amplify the effect [22].

The European Central Bank faces what CNBC described as a "genuine dilemma" [8]. Europe imports nearly all of its oil and a significant share of its LNG, creating the risk of a dual energy and trade shock. Raising interest rates to contain oil-driven inflation would risk deepening an already fragile growth outlook. Holding rates steady could allow inflation expectations to become unanchored. There are no good options.

Asia Bears the Brunt

While headlines have focused on Western markets, the heaviest economic blow may fall on Asia. India faces the largest combined exposure, with more than half of its LNG imports Gulf-linked and approximately 60% of its oil imports originating from the Middle East [2]. The crisis creates what Oxford Economics describes as a "dual physical and financial shock" for the Indian economy [11].

Japan's vulnerability is even more acute in some respects. The country depends on imported fossil fuels for 87% of its total energy use, and 95% of its crude oil imports originate from the Middle East [2]. A sustained closure of the strait could sharply widen Japan's trade deficit, weaken the yen, and tip the economy toward stagflation.

Across emerging Asia more broadly, BNN Bloomberg reported that a supply-driven jump in Brent crude from $70 to $85 would add roughly 0.7 percentage points to inflation and knock about 0.5 points off economic growth [23]. For economies already navigating the aftereffects of the pandemic, trade tensions, and currency pressures, this is a blow they can ill afford.

The Policy Response: Too Little, Too Late?

Policymakers are scrambling to respond, but the toolkit is limited. OPEC+ lifted its output target for April by 206,000 barrels per day — a move that was already planned but has taken on "far more consequential" significance in the current environment [24]. However, with the strait itself effectively closed, additional OPEC production from Gulf states faces the same transit problem as existing supply.

The Trump administration could tap the Strategic Petroleum Reserve, which currently holds approximately 415 million barrels [12]. But experts caution that the SPR is designed to smooth short-term shocks, not offset a sustained structural disruption to global supply. If the Hormuz closure persists for weeks or months, the reserve would be a band-aid on a wound that requires surgery.

The fundamental problem is that no policy response can substitute for the physical reopening of the strait. Until commercial shipping can safely transit the Hormuz corridor, the global energy market will remain in a state of acute stress.

What Comes Next

The trajectory of markets now depends almost entirely on the trajectory of the conflict. Goldman Sachs' four-week estimate reflects a base case in which hostilities de-escalate relatively quickly, allowing shipping to gradually resume. In that scenario, oil prices ease back toward the mid-$60s by late Q2, and the inflationary impact remains manageable [10][12].

But the downside scenarios are severe. A protracted closure pushing Brent toward $100 would trigger what Bloomberg has called a threat to the "global economic recovery" — potentially tipping vulnerable economies into recession while simultaneously stoking inflation [25]. The energy shock would compound existing stresses from trade policy uncertainty, elevated interest rates, and geopolitical fragmentation.

For now, markets are watching three things: the pace of military operations, the status of diplomatic channels, and the willingness of non-Gulf producers — particularly the United States, Brazil, and Guyana — to ramp up supply to partially offset the lost barrels. Each day the strait remains closed, the economic costs compound and the risk of a broader market dislocation grows.

Five days into the crisis, the world's most important energy chokepoint remains dark. The question is no longer whether the conflict will impact global markets — it already has. The question is how deep and how lasting the damage will be.
