Bitcoin dipped below the $91,000 mark following reports of heightened geopolitical tensions in the Atlantic. U.S. forces intercepted a Russian-flagged oil tanker in international waters, escalating energy sector concerns and triggering broader market volatility across risk assets. The price correction reflects investor anxiety over potential sanctions escalation and its ripple effects on global energy markets and macroeconomic stability. Such geopolitical events typically amplify crypto's sensitivity to macro-level uncertainty, with traders reassessing risk exposure in volatile periods.
