New Zealand’s Treasury projects inflation could hit 7.4% in 2025-26 if the Iran war persists, while the Polymarket contract for a Fed rate hold in July trades at 81.5% YES.

Market reaction

The Fed’s July meeting market, at 81.5% YES odds, shows traders expect rates to stay put. Daily face value is $4,573, with $3,727 in actual USDC traded. It would take $4,120 to shift the odds 5 points, indicating solid liquidity and strong conviction in a hold. The Bank of Japan’s April meeting market sits at 0.1% YES for a rate decrease, showing near-total skepticism of a cut even with global oil price pressure. The ECB’s April decision carries more uncertainty as the conflict raises energy costs across Europe.

Why it matters

The Iran conflict has pushed oil prices higher, and New Zealand’s 7.4% inflation projection illustrates how a prolonged war could ripple through smaller open economies. For the Fed, though, the connection is less direct. The 81.5% hold probability suggests traders see the U.S. as relatively insulated from this particular inflation channel, at least through July.

What to watch

Fed Chair Jerome Powell’s upcoming statements and any escalation in the Iran conflict. If fighting intensifies, expect more volatility in interest rate markets across Polymarket. At 18¢, a YES share in the Fed hold market pays $1 if rates remain unchanged, a 5.5x return. That bet requires believing geopolitical tension continues without triggering direct economic disruption in the U.S.
