JD Vance Cancels Pakistan Trip as Iran Tensions Spike, WLDOIL Surges $4

US Vice President JD Vance canceled his Pakistan trip on April 21, 2026, amid spiking US-Iran tensions and Strait of Hormuz supply fears, driving June WTI crude (WLDOIL) up roughly $4. This escalates from an earlier postponement report the same day, amid stalled talks demanding a blockade lift and Israel's war readiness signals. The risk-off reaction saw S&P 500 drop 0.5%, Bitcoin slide toward $75,000, and over $250 million in crypto liquidations, continuing a volatile week after April 13's naval escalation, a brief April 15 ceasefire, and April 16's failed congressional vote.
