Warsh Era Begins as Hormuz Crisis, Bond Selloff Rattle Global Markets

Global markets absorbed a triple shock on May 15: a leadership transition at the Federal Reserve, a diplomatically hollow Trump-Xi summit, and the continuing hemorrhage of oil supply through the Strait of Hormuz closure. The S&P 500 (SPY) shed 0.35% to close at 739.17, Nasdaq (QQQ) fell 0.17% to 708.93, and the 10-year Treasury yield climbed to 4.595% — up roughly 9 basis points on the day and near a one-year high — as markets priced a stagflationary trajectory with 45% odds of a Fed rate hike before year-end per CME FedWatch. WTI crude surged 3.29% to $105.42, while the dollar index firmed 0.34% to 99.27.

Kevin Warsh was sworn in as the 17th Federal Reserve Chair as Jerome Powell's term expired, marking the most consequential leadership handoff at the Fed in decades. His 54-45 Senate confirmation — the most partisan in Fed history — arrives just as April CPI hit a three-year high and PPI accelerated to 6% year-over-year. Warsh's hawkish posture on the balance sheet and skepticism of QE inject fresh uncertainty into an already fractured rate outlook; his inaugural FOMC meeting on June 16-17 will be the first major test of his credibility. Bond markets delivered an immediate verdict: the 10-year yield's push toward 4.6% and UK gilts rising 15 basis points signal that investors are demanding a higher term premium globally.

The Trump-Xi summit in Beijing concluded with modest deliverables — a Chinese commitment to purchase U.S. oil and 200 Boeing aircraft, plus a vague three-year 'strategic stability' framework — but no actionable progress on reopening the Strait of Hormuz. The IEA's May Oil Market Report quantified the damage: global oil supply has fallen 12.8 mb/d since February, the largest disruption in recorded history, with Brent having already peaked above $144/bbl in April. China's oil purchase pledge pushed crude higher on the session but simultaneously underscored the supply vacuum; precious metals bore the brunt of dollar strength and real-rate anxiety, with gold falling roughly 2.7% and silver dropping 7-8% intraday, though GLD's end-of-day decline moderated to 0.08%.

U.S. economic data painted a resilient but inflationary picture that complicates the Fed's path. April retail sales rose 0.5% month-over-month — just below the 0.6% consensus — with gasoline accounting for an outsized share of the gain; core ex-auto sales advanced 0.7%. The Empire State Manufacturing Index exploded to 19.6 in May from 11.0 in April, the strongest print in four years and well above the 6.2-7.8 consensus, with the prices-paid subcomponent climbing alongside new orders — precisely the input-cost pressure that argues against any near-term Fed easing.

Markets will now focus squarely on Warsh's first public remarks as Chair and any signals ahead of the June 16-17 FOMC meeting, where a hawkish hold or surprise hike could reprice the entire Treasury curve. The Iran conflict trajectory remains the paramount wildcard: any diplomatic opening on the Strait — or further escalation — would instantly reorder crude, inflation, and rate expectations. Watch the June FOMC dot plot, the next IEA supply update, and whether Beijing follows through on its oil purchase commitments as barometers for the summer macro regime.
