Congress Members Loaded Up on Defense and Oil — Before the Iran Strikes

The Timeline

On February 28, 2026, the United States and Israel launched coordinated military strikes against Iran, targeting nuclear facilities and military command infrastructure. Iran's Supreme Leader Ayatollah Khamenei was killed in the strikes. Oil markets reacted immediately — Brent crude surged 13% to $82 per barrel, a 14-month high, as the effective closure of the Strait of Hormuz threatened global oil supplies.

Defense stocks surged in parallel. The iShares US Aerospace & Defense ETF (ITA) was already up 14% year-to-date before the strikes, and extended further on the news. Raytheon (RTX), Lockheed Martin (LMT), and Northrop Grumman (NOC) all hit 52-week highs.

But some members of Congress were already positioned.

The Trades

Public STOCK Act filings reveal a pattern of defense and energy purchases by US Senators in the weeks before the strikes:

Senator Markwayne Mullin (R-OK)

Committee: Armed Services, Environment and Public Works
Trade Date: December 29, 2025
Disclosed: January 16, 2026

Mullin also purchased VSEC (VSE Corporation), a defense services contractor, on January 5 — now up +12.3%.

Notably, Mullin sits on the Armed Services Committee, which receives classified briefings on national security threats, military readiness, and defense procurement. This is what researchers call a committee-aligned trade — when a member trades stocks directly within their committee's jurisdiction.

Senator John Boozman (R-AR)

Committee: Appropriations (Defense subcommittee)
Trade Date: January 8, 2026
Disclosed: February 15, 2026

Boozman serves on the Appropriations Committee's Defense subcommittee, which controls the military budget. His XOM position was disclosed in a public STOCK Act filing on February 15, 2026.

Why This Matters

We are not claiming insider trading. Every trade listed here was:

• Legally executed under current law
• Publicly disclosed within the timeframe required by the STOCK Act (within 45 days)
• Available to any investor who monitors congressional filings

The question isn't whether these trades are legal — they are. The question is whether the information asymmetry that congressional committee membership provides constitutes a structural advantage in the markets.

The Academic Evidence

Research from Eggers & Hainmueller (2014, Quarterly Journal of Political Science) found that members' investments in politically-connected firms — local companies, campaign contributors, and firms lobbying their committees — have historically outperformed members' other holdings by roughly 3% annually. The connection between committee jurisdiction and portfolio positioning is what makes these trades worth examining: Armed Services Committee members trading defense stocks, Banking Committee members trading banks, Energy Committee members trading oil.

The filters worth watching are:

• Committee alignment — whether the traded sector falls within the member's jurisdiction and briefing access
• Timing relative to legislative activity — trades placed during active sessions on committee-relevant matters
• Large transactions (>$50K signals higher conviction)

Sen. Mullin's trades illustrate the alignment pattern: Armed Services member, defense and oil stocks, sizable positions ($15K-$50K each), purchased during a period of escalating US-Iran tensions.

The Broader Context

Mullin's December 29 buying spree wasn't limited to defense and oil. On the same day, he purchased over $1 million across 30+ positions including $NVDA ($100K-$250K), $AAPL ($100K-$250K), $GOOGL ($100K-$250K), and $AMZN ($100K-$250K). This was a broad market allocation, not a targeted defense play.

However, the defense and oil positions stand out for two reasons:

1. Committee alignment: Mullin's Armed Services seat gives him direct access to national security intelligence
2. Timing: US-Iran tensions had been escalating since January 2026, with Iranian officials warning they were "ready for war" as early as January 13

The broader portfolio context doesn't eliminate the signal — it contextualizes it. Even within a diversified allocation, the specific inclusion of RTX, CVX, COP, and VSEC by an Armed Services Committee member, purchased weeks before a military conflict, is a data point worth tracking.

What Can Investors Learn?

Congressional trade disclosures are public data. Under the STOCK Act, all members of Congress must report trades within 45 days. These filings are available through the SEC and aggregated by platforms like Meridian.

Three Filters That Matter

1. Committee Alignment
Not all congressional trades are equal. A Finance Committee member buying bank stocks carries more signal than a Judiciary Committee member buying the same. Always check the member's committee assignments.

2. Transaction Size
Trades above $50,000 signal higher conviction. Mullin's defense positions were $15K-$50K each — meaningful but not his largest bets (those were tech stocks at $100K-$250K).

3. Cluster Detection
When multiple members from the same committee buy similar sectors within weeks of each other, the signal strengthens. In this case, both Mullin (Armed Services) and Boozman (Appropriations-Defense) independently bought energy and defense names in the same window.

The Bigger Picture

The Iran strikes mark the most significant US military engagement since the 2003 invasion of Iraq. Markets are still processing the implications:

• Oil: Brent at $82, with analysts projecting $90+ if Strait of Hormuz disruption persists
• Defense: ITA up 14% YTD, with order backlog projections rising across the sector
• Safe havens: Gold, treasuries, and the US dollar all strengthening
• Risk assets: Broad market selling as investors reprice geopolitical risk

The congressional filings won't tell you the future. But they reveal what some of the most well-informed people in Washington were buying with their own money — a public data point that, combined with other signals, is worth tracking on its own merits.

Key Takeaways

• Multiple US Senators purchased defense and oil stocks 2-3 months before US-Israel strikes on Iran
• Sen. Mullin (Armed Services Committee) bought RTX, CVX, COP — all up 14-27%
• Sen. Boozman (Appropriations-Defense) bought XOM — up 25%
• These are committee-aligned trades — investments in politically-connected firms have historically outperformed members' other holdings by roughly 3% annually (Eggers & Hainmueller, 2014)
• All trades were legally disclosed in public STOCK Act filings
• Congressional trade signals are most valuable when filtered for committee alignment, transaction size, and cluster patterns
