The Dollar’s War-Driven Rally Challenges the Fed’s Credibility

The mechanism driving this surge is clear: rising tensions in the Strait of Hormuz threaten a fifth of the global oil supply, fueling fears of a supply-driven inflation spike. Federal Reserve Chair Kevin Warsh, already under pressure to prove his hawkish credentials after a shaky July, now faces a dilemma where he cannot afford to look soft as energy prices climb. Futures markets have reacted sharply, pivoting from expectations of a policy hold to pricing in a hike at the September 15–16 meeting.

This tightening environment creates a specific set of winners and losers. Holders of short-dated Treasury bills and stablecoin issuers benefit as their underlying assets yield higher returns. Conversely, emerging markets face a crushing double burden: the rising cost of servicing dollar-denominated debt coincides with an increased local-currency price for oil imports. Gold remains caught in the crossfire, balancing safe-haven demand against the gravity of higher interest rates.

While the dollar’s long-term decline in central bank reserves persists—dropping to 57.13% according to recent IMF data—its influence is quietly expanding through stablecoins. Should the GENIUS Act framework move forward, demand for Treasuries from these digital assets could reach $2.3 trillion. For Washington, the immediate challenge is managing this collateral leverage: a rate hike during a conflict raises borrowing costs just as the government requires affordable financing, potentially alienating partners who are least equipped to absorb the impact of a stronger dollar.
