30-year U.S. Treasury yields have breached 5% as Jerome Powell leaves the Federal Reserve without a successor in place. CPI holds at 3.8%. Bond markets from Washington to London are pricing in persistent inflation — not a temporary blip.
UK gilts have climbed to 1990s highs. The revolt in global fixed income is coordinated: investors worldwide doubt any major central bank can deliver inflation back to target on schedule.
Services inflation remains above 3% annually in the U.S.1 Wages and healthcare costs resist rate hikes. The Iran war has compounded a supply-side shock: U.S. household gasoline costs are up $857 in 2026, per the Stanford Institute of Economic Policy Research.2
The Fed faces a stagflation dilemma with no experienced hand at the helm. Raising rates risks cratering a debt-laden economy. Holding rates risks entrenching inflation expectations globally. A new chair without Powell's institutional credibility starts from a deficit on day one.
AI has not delivered the productivity boost many hoped would inflate away debt through growth. MIT economist Daron Acemoglu finds no measurable productivity effect yet.3 AI agents augment specific tasks — they do not replace whole roles.3
The AI investment surge raises a separate alarm. U.S. AI investment is nearly a third greater than dot-com-era internet investment at its peak, per former White House economist Jared Bernstein.4 A deflating bubble would hand the next Fed chair a growth shock on top of the inflation problem.
Diplomatic signals offer partial relief. The Trump-Xi summit and U.S.-China tariff concessions ease some goods-price pressure. G7 supply-chain coordination is under way. None of this resolves services or energy inflation.
The 5% yield on 30-year Treasuries is the market's verdict: global investors no longer believe the Fed has the institutional coherence to hit its inflation target on schedule.
