US Treasury yields rise as US-Iran tensions escalate

US Treasury yields are climbing, with the two-year yield up 8.4 basis points to 3.80%, as the US-Iran conflict escalates. The Polymarket contract for no change in Fed rates after the July 2026 meeting sits at 78.5% YES, down from 84% a week ago.

Market reaction

Geopolitical tensions have introduced a “term premium,” pushing yields higher across maturities. The odds for no change in July dropped 5.5 points over the past week, tracking rising concerns about military escalation and conflict-driven inflation pressure. The White House ultimatum expires on April 7, 2026, which adds urgency.

Daily volume on the contract is $1,082 face value ($849 in actual USDC), with $4,358 needed to move the odds by 5 points. That thin liquidity makes the market sensitive to large trades. The largest price move in the last 24 hours was modest, consistent with steady trading rather than volatility spikes.

Why it matters

Rising Treasury yields signal that markets are pricing in sustained geopolitical risk and its effect on monetary policy. Traders buying YES on no rate change are betting against further escalation and against a surprise inflation surge. At 78.5¢, a YES share pays $1 if the Fed holds rates steady, a 1.27x return.

What to watch

Any comments from Fed Chair Jerome Powell or other governors about policy shifts will move this market. Specifically, changes in language around “data dependency” or explicit references to geopolitical risk would be the trigger. The next major catalyst is Powell’s address at the upcoming FOMC meeting.
