CPI Ran Hot. Equities Made Records. Bonds Ran Hotter.

Equity markets cleared the 3.8% CPI beat by reading the tariff truce as a temporary inflation ceiling. The 30-year auction cleared at 5.046% on weak demand, with supply pressure doing work the inflation read alone cannot explain.

April CPI came in at 3.8% on May 12, a tenth above consensus and the hottest print since May 2023. The S&P 500 closed at 7,444, a new all-time high.

The U.S.-China tariff truce gave buyers their frame. American duties on Chinese goods had fallen from 145% to 30%, and CPI's energy component accounted for more than 40% of the headline gain. Equity buyers read the beat as trade-linked and temporary.

April PPI, reported May 13, told a different story: monthly prices rose 1.4% against a 0.5% forecast, and core PPI added 1.0% against a 0.3% consensus. Services and non-energy goods drove the core overage, the categories no tariff deal touches.

The 30-year Treasury auction on May 13 cleared at 5.046%, the first time above 5% since August 2007. Bid-to-cover came in at 2.303, below the six-auction average of 2.43 and the weakest since November 2025. The government issued $691 billion in Treasury securities that week, $155 billion in notes and bonds, adding supply pressure at the long end independent of the inflation signal.

The auction figures reveal the asymmetry. Equity buyers could apply a tariff-truce discount to the energy-driven CPI beat; no equivalent discount exists for $691 billion in new Treasuries arriving with weakening demand.

Kevin Warsh was confirmed as Fed chair 54-45 on May 13, the day PPI landed. Trump nominated him expecting rate cuts; the 2-year yield at 4.079% had already priced out every 2026 cut. Warsh arrives with a rate-cutting mandate and a voting record from his first Fed stint that ran hawkish even when unemployment was surging.

Watch the May core PPI print, due mid-June at Warsh's first FOMC. If month-over-month holds at or above 1.0%, the market that priced out all 2026 cuts by May 15 has the better read on what comes next.
