The US bond market just got the number it was waiting for. June’s Consumer Price Index came in at negative 0.4% month-over-month, marking the first outright decline in consumer prices since 2020, and traders responded exactly how you’d expect: by ripping up their rate hike playbooks.

The annual inflation rate dropped to 3.5%, a reading soft enough to send Treasury yields sliding and force a rapid unwinding of options positions that had been betting on at least one more Federal Reserve rate increase this year.

The trade that died on arrival

SOFR options activity, the derivatives market where traders express views on short-term interest rates, saw a dominant move toward put selling as participants closed out positions that had been structured around a hawkish Fed.

Zach Griffiths of CreditSights put it bluntly: “Today’s print takes a July hike off the table.”

Markets have now repriced their expectations dramatically. Where traders had previously been positioning for potentially aggressive tightening, the consensus has shifted to at most one additional rate hike by mid-2027.

The rally was most pronounced at the front end of the Treasury curve, where yields are most sensitive to near-term Fed policy expectations.

Adding fuel to the bond bull case, Producer Price Index data released alongside the CPI report came in equally benign.

Why inflation scared everyone in the first place

Earlier in 2026, the inflation picture looked considerably less friendly. Geopolitical tensions and oil price fluctuations had pushed price pressures higher, creating genuine uncertainty about whether the Fed would need to resume tightening after what many had hoped was a terminal pause.

That uncertainty seeped into everything. Bond volatility spiked, options markets priced in multiple potential hike scenarios, and the fixed-income world operated under a cloud of “what if the Fed isn’t done.”

What this means for crypto and risk assets

When Treasury yields fall, the opportunity cost of holding non-yielding assets like Bitcoin decreases. The repricing of rate expectations from “multiple hikes possible” to “maybe one more hike over the next year” represents a meaningful easing of financial conditions, even without the Fed actually cutting rates.

The caveat worth watching: one month of soft data doesn’t make a trend. The gap between 3.5% annual inflation and the Fed’s 2% target remains wide enough to keep policy uncertainty alive.
