The put-to-call volume ratio on the crypto derivatives exchange Deribit surged to 2.17 over the past 24 hours, reflecting a strong tilt toward protective bets. Put options, which offer downside insurance by giving the holder of the contract the right to sell at a certain price, saw outsized demand, particularly in short-dated contracts. For options expiring June 20, open interest in puts struck at $100,000 now tops the board, with a put-to-call ratio of 1.16, underscoring concern about a near-term price fall.

Bitcoin reached an all-time high of $111,980 on May 22, and is up more than 50% since a now crypto-friendly Donald Trump was elected president of the U.S. for a second time in November. The largest cryptocurrency was little changed at about $104,377 on Wednesday. 

The caution comes as Federal Reserve policymakers navigate a highly uncertain environment as geopolitical tension in the Middle East and volatile energy prices add to inflation and labor market risks tied to the Trump administration’s tariff policies. With U.S. officials widely expected to hold policy steady for a fourth straight meeting later Wednesday, markets will focus on the Fed’s latest projections for growth, unemployment and interest rates.

“A hawkish signal from the Federal Reserve could strengthen the US dollar and trigger a test of the psychological $100,000 mark,” Javier Rodriguez-Alarcón, chief investment officer of XBTO, wrote in a note.  “Simultaneously, the geopolitical situation remains a wildcard; any credible de-escalation in the Middle East could serve as a significant risk-on catalyst, while a further deterioration would likely trigger another move down across risk assets.”
