Sectors and Politicians Who Profited from the Iran War

As global energy prices soared and defence budgets swelled in the wake of the US-Israel war in Iran, households and small businesses bore the brunt of economic disruption. But a parallel story was unfolding in Washington, D.C., one where some members of Congress appeared to be positioning their personal portfolios to capitalise on the very sectors heating up around the conflict.

A review of Capitol Trades disclosure data, covering transactions from January 1, 2026 onward across oil and gas, banking, aerospace and defence, and renewable energy stocks, reveals dozens of trades by sitting legislators in companies that have since reported record earnings or seen their share prices surge amid the war's economic fallout.

Energy Markets Ignite, and So Do Congressional Portfolios

The closure of the Strait of Hormuz at the end of February 2026 sent shockwaves through global energy markets. Around a fifth of the world's oil and gas transits that chokepoint, and the effective halt to those shipments triggered violent price swings that benefited the trading arms of Europe's oil giants. BP's first-quarter profits more than doubled to $3.2 billion. Shell beat analyst expectations with $6.92 billion in quarterly earnings. TotalEnergies saw profits jump by nearly a third to $5.4 billion.

Congressional trading records suggest some lawmakers were already building positions in the sector as tensions escalated.

Rep. Gil Cisneros made a series of oil and gas purchases on March 10, just days after Iran's effective closure of the strait began to register in markets. His buys included EOG Resources, Occidental Petroleum, Targa Resources, ConocoPhillips, Williams Companies, and Kinder Morgan, a concentrated sweep across the sector. EOG Resources has since risen roughly 15% from his purchase price; Targa Resources gained more than 14%.

Sen. John Boozman bought ExxonMobil shares on February 15 at approximately $122.91. ExxonMobil's price has since risen to $144.57, a gain of roughly 17.6%, even as the company's overall profits dipped compared to the prior year due to supply disruptions, with executives expecting growth to accelerate as the price of oil remains well above pre-war levels.

Rep. Josh Gottheimer added ExxonMobil to his portfolio in mid-March at around $138, with the stock now trading at $144.57, a modest gain, though still meaningful in a volatile environment.

The Bank Bonanza

While oil companies benefited from price volatility, Wall Street's biggest institutions profited from something even more straightforward: the sheer volume of trading that fear and uncertainty generate. JPMorgan Chase's trading arm posted a record $11.6 billion in revenue in the first quarter of 2026. Across the "Big Six" banks, combined profits reached $47.7 billion in a single quarter.

Members of Congress were active in the sector throughout the period.

Sen. Markwayne Mullin purchased Citigroup shares in early February at around $123. Citigroup now trades at $125.55, a gain of roughly 1.8%, modest in absolute terms, but part of a broader pattern of financial sector positioning by the senator. He added more Citigroup in March at a lower entry point of $117.43, booking a gain of approximately 6.9% on those shares.

Rep. Jonathan Jackson made multiple Citigroup purchases across February and March, including one tranche in mid-March valued between $50,000 and $100,000 at $115.74 per share. Citigroup has since moved to $125.55, an 8.5% gain on that position.

Rep. Ro Khanna was among the most active congressional traders in the banking sector, with a complex series of buys and sells across JPMorgan Chase, Wells Fargo, Truist Financial, Bank of America, and various international banks, including corporate bond positions. On April 9, he purchased JPMorgan shares at $283.77; the stock now trades at $302.10, a gain of about 6.5%. He also bought Bank of America at $48.56 on the same date, now up 5.7% to $51.31.

Sen. Mark Warner purchased Fifth Third Bancorp on May 1 at $44.19, with the stock now at $49.33, an 11.6% gain in just ten days. He also sold Cheniere Energy, an LNG company, on the same date at $280.89. Cheniere has since fallen to $240.11, meaning Warner effectively locked in profits before a 14.5% decline.

Defence Contracts and Congressional Wallets

The conflict has driven a rapid acceleration in defence procurement across Europe and the United States, with governments rushing to replenish depleted weapons stocks and invest in missile defence and counter-drone systems. BAE Systems cited growing "security threats" in a recent trading update. Lockheed Martin, Boeing, and Northrop Grumman each reported record order backlogs at the close of the first quarter.

Sen. Markwayne Mullin purchased Carpenter Technology, a specialty alloys manufacturer whose materials are used in aerospace and defence applications, twice in early 2026. His February buys were made at around $340 per share; the stock has since climbed to $427.85, a gain of roughly 25.6%. A follow-up purchase in March at $334.19 has also gained approximately 28%.

Rep. Maria Elvira Salazar purchased Boeing shares on April 22 at $201.18. Boeing, one of the world's largest defence contractors, now trades at $237.36, a gain of approximately 18%. She also bought Citigroup on the same date, up 14.3% since her purchase.

Rep. April McClain Delaney bought TransDigm Group, an aerospace components manufacturer, across multiple transactions on May 7, at prices ranging from around $1,142 to $1,274. TransDigm's current price of $1,215.08 leaves some of those purchases slightly underwater and others modestly profitable, suggesting more recent and less clearly timed positioning.

A Pattern Worth Scrutinising

None of the trades documented here are necessarily improper. Members of Congress are required to disclose stock trades under the Stop Trading on Congressional Knowledge (STOCK) Act, and the trades described are part of the public record. Correlation between a lawmaker's committee assignments, legislative knowledge, or policy access and their investment decisions is difficult to prove and legally complex to prosecute.

But the pattern raises persistent questions about whether the wallbetween legislative work and personal financial gain is as firm as the public interest demands. As millions of households contend with higher petrol prices, rising energy bills, and the broader economic turbulence sparked by the Iran war, a subset of their elected representatives have recorded double-digit gains in the very sectors being discussed in congressional hearings and committee briefings.
