Fed futures open interest hits record before rate decision

The interest rate futures market just got very, very crowded. SOFR futures open interest surged past 15.8 million contracts in recent weeks, an all-time record, as traders positioned themselves for what could be a pivotal Federal Reserve decision at the July 29 FOMC meeting.

The numbers behind the frenzy

The SR3 contract, the workhorse instrument for leveraged funds betting on short-term interest rates, hit a record open interest of 14.2 million contracts. Leveraged funds have been piling into short positions at a pace that suggests genuine conviction, not just hedging.

One specific contract tells the story particularly well. The SR3Z6, a December-dated SOFR contract, saw its open interest jump 28% over two months, surpassing 1.8 million contracts.

Total short-term interest rate futures open interest peaked at 18 million contracts across the board. The ZQ contract, which tracks 30-day Fed funds rates, exceeded 2.5 million contracts on its own.

The CME FedWatch tool showed rate hike odds for the July meeting fluctuating from as low as 7% to as high as 38%, eventually stabilizing in the 32-38% range as the meeting approached.

What this means for crypto investors

Bitcoin spent the lead-up to the FOMC announcement trading in a range between $63,000 and $65,500. Higher rates strengthen the dollar, increase the opportunity cost of holding non-yielding assets like Bitcoin, and generally tighten the financial conditions that fuel speculative appetite.

Ethereum has shown similar sensitivity to rate expectations, trading in a compressed range alongside Bitcoin. The correlation between crypto assets and traditional macro indicators has only deepened over the past few years as institutional participation has grown.

With 32-38% hike odds priced in, a no-action outcome would effectively mean the market overestimated hawkishness. The July 29 decision represented a pivotal moment for traders anticipating the central bank’s first rate hike after a protracted period of holding rates within the 3.50-3.75% corridor.
