U.S. Deploys Multi-Lever Energy Strategy as Iran War Threatens Economic Stability

The U.S. is releasing 172 million barrels from the Strategic Petroleum Reserve as part of a coordinated 400 million barrel global release, the largest emergency deployment in history, as oil prices breach $100 per barrel amid Iran conflict disruption to global energy flows. Energy Secretary Chris Wright announced the release on 11 March, per the Department of Energy, with deliveries beginning 16 March and continuing over 120 days.

The U.S.-Israeli strikes on Iran that began 28 February have effectively closed the Strait of Hormuz to commercial shipping, according to Al Jazeera, with daily transits collapsing from 138 vessels before the war to fewer than five. The waterway normally carries roughly 20 million barrels per day. Iranian Supreme Leader Mojtaba Khamenei has pledged to maintain closure, while at least 16 commercial vessels have been attacked since hostilities began.

Market Response Reveals Policy Limits

The coordinated reserve release has failed to stabilize prices. Brent crude traded above $101 per barrel on 13 March despite the IEA announcement, up nearly 40% from pre-conflict levels, per Al Jazeera. Oil spiked to $119.50 intraday before retreating as traders priced in a daily supply shortfall estimated at 15–20 million barrels.

The administration simultaneously deployed Sanctions relief. President Trump announced on 9 March that the U.S. would “take those sanctions off until this straightens out,” S&P Global reported, without specifying which countries. Treasury Secretary Scott Bessent issued a 30-day waiver on Russian oil sales to India on 6 March, while Trump offered political risk insurance to tankers willing to transit the strait.

OPEC+ Coordination Faces Geographic Constraints

OPEC+ added 206,000 barrels per day in April production, The Moscow Times reported, exceeding the expected 137,000 bpd by 50%. But the increase offers limited relief: Saudi Arabia raised February output by 340,000 bpd to 10.34 million, per Bloomberg, yet Gulf producers have since shuttered 8 million bpd of crude production due to the Hormuz closure. Tanker shipments from the region have nowhere to go, forcing production cuts even as global demand remains unmet.

Spare capacity is concentrated in Saudi Arabia and the UAE at roughly 2.5 million bpd combined, per Kpler. But that capacity cannot reach global markets while the strait remains closed. Alternative pipeline routes exist but cannot offset a full closure. Iraq has already halted production at its largest field following Iranian attacks.

Inflation Transmission Accelerates

The energy shock is already propagating through the economy. U.S. average gas prices reached $3.63 per gallon as of mid-March, up 22% from $2.98 before the conflict, per CBS News. San Francisco hit $6.50 per gallon, while California prices surged above $5. Diesel prices jumped nearly $1 per gallon in the week ending 9 March, the highest weekly increase on record.

Goldman Sachs projects headline Inflation could rise from 2.4% toward 3% by year-end, according to the firm’s analysis, though February CPI data preceded the conflict outbreak. European analysts estimate eurozone inflation could peak near 2.5% in March–April before retreating, assuming prices stabilize around $80 per barrel, per Euronews. If oil reaches $100 for an extended period, eurozone inflation could average 2.4% across 2026 with quarterly peaks above 3%.

Military Solution Required for Market Normalization

Wright has offered conflicting timelines. He told NBC’s Meet the Press on 15 March that the conflict would likely last “a few more weeks,” per Newsweek, consistent with earlier statements that operations would take “weeks, certainly not months.” But he told CNBC on 13 March that the U.S. Navy was “not ready” to escort tankers, with operations potentially beginning by month-end at earliest.

Defense Secretary Pete Hegseth stated bluntly on 13 March: “The only thing prohibiting transit in the straits is Iran shooting at shipping,” per CNBC. Analysts warn even Navy escorts would not restore normal tanker traffic. The International Energy Agency estimates the war will cut global oil supply by 8 million barrels per day in March, a gap that reserve releases cannot sustainably fill.

Trump has oscillated between declaring victory imminent and warning of protracted operations. He said 10 March the war would be over “very soon” while simultaneously stating attacks would continue “until the enemy is totally and decisively defeated.” The expanding war effort carries uncomfortable echoes of the Iraq War, where tens of thousands of U.S. troops on the ground proved insufficient to end violence over nine years.

What to watch

The critical variable is conflict duration. If military operations restore Hormuz transit within weeks as Wright projects, markets could stabilize below $80 per barrel as physical supply normalizes. But if the strait remains effectively closed into April, the 400 million barrel reserve release provides only temporary cushion against a 15–20 million barrel daily shortfall.

Monitor three indicators: Hormuz transit counts (currently 4–5 vessels daily versus 138 pre-war), U.S. Navy escort announcements (Wright suggested late March as earliest), and OPEC+ emergency meeting calls. The longer Gulf producers remain unable to export existing production, the more pressure builds for either diplomatic resolution or expanded military operations to reopen shipping lanes.

Inflation data will lag by 4–6 weeks. March CPI, released mid-April, will capture the first full month of elevated prices. If oil remains above $90 through April, expect headline inflation to breach 3% by summer, complicating Federal Reserve policy amid already elevated core inflation at 2.5%. European Central Bank rate hike probability has surged from 12% pre-conflict to 42%, reflecting market reassessment of monetary policy trajectory. Energy security has collided with inflation management, and markets are pricing the possibility that neither problem can be solved through economic policy alone.
