Oil futures have fallen over 8% since last Friday as the collapse of SVB Financial (SIVB.O) and peer Signature Bank (SBNY.O) prompted concerns of a wider banking crisis.
Investors in the oil market, including oil producers, have rushed to buy put options, used to either bet on or protect against downside movement.
For U.S. crude futures options open interest, the ratio of puts to calls is the highest since August 2022.
The discount of later-dated oil futures contracts to the front-month contract tightened on Wednesday, indicating that market participants were less confident in short-term demand.
That short-term uncertainty should buoy put buying, Price Futures Group's Flynn said.
