The cost of options hedges against further gains in US Treasuries surged to its highest level since March on Thursday as investors sought government bonds for safety.
Yields on the benchmark 10-year Treasury dropped below 5% for the first time in about a month, with traders paying a higher premium for call options over put options.
The market moves were driven by spiking oil prices amid Middle East conflict worries, artificial intelligence trade jitters, and escalating French bond stress.
