The United States launched fresh military strikes on Iran on 30 July 2026, following an attack on American forces in Jordan, widening the Middle East conflict. Simultaneously, the Federal Reserve held benchmark interest rates unchanged for a seventh consecutive month. The combination of geopolitical escalation and the Fed's policy stance drove a sharp reaction across multiple asset classes, according to Bloomberg Markets.
The 30-year US Treasury yield jumped 14 basis points to 5.23%, a 19-year high, as inflation expectations rose following the dual developments. US equity indices fell, with the Nasdaq 100 declining 2.06%, the S&P 500 down 1.52%, and the Dow down 2.19%, per Finnhub. The US dollar weakened against major currency pairs, including the euro.
The 30-year Treasury yield (UST30Y) moved directly in response to the Fed decision and geopolitical escalation, reaching its highest level in nearly two decades. WTI crude oil is the benchmark for US crude pricing and has direct exposure to Middle East supply disruption risk, with energy prices rising following developments in the Iran situation. Gold also moved during the session, reflecting the combined geopolitical and monetary policy uncertainty.
The Federal Reserve's decision was reached by a 9-3 vote, with three board members dissenting in favour of an immediate rate increase — the first three-way dissent in a decade, according to Guardian Business. Fed Chair Kevin Warsh shifted away from forward guidance, stating that economic data and bond markets would drive future policy decisions, a stance that drew criticism from investors over the Fed's inflation-fighting credibility, per Bloomberg Markets.
