# Strait of Hormuz and Red Sea energy security disruptions > Live situation record from CLSTR: https://clstr.news/situations/strait-of-hormuz-energy-security-disruptions > Updated: 2026-09-21T11:20:55.000Z. Sources: 103. Developments: 5. The conflict between the United States and Iran has escalated, resulting in the closure of the Strait of Hormuz and the severance of 14 percent of global oil output. Despite this disruption, global oil prices have remained relatively stable, bolstered by a 400 million barrel release by the International Energy Agency and significant, quiet injections from China’s estimated 1.4 billion barrel stockpile. Tensions have spiked following the destruction of two Iranian boats by US forces; while US officials claim the vessels were attempting to seize a naval drone, Iran maintains they were fishing boats. Simultaneously, the Saudi-led coalition reported shooting down a Houthi drone targeting Mecca, reflecting the ongoing expansion of regional threats. As the United Nations General Assembly convenes, oil prices have experienced heightened volatility. While Brent crude previously fluctuated around the $100 per barrel mark, prices have recently fallen for four consecutive sessions, with Brent dropping below $100 and West Texas Intermediate (WTI) falling by over 5%. This decline follows indications of potential de-escalation. Diplomatic signals have shifted as President Donald Trump expressed openness to meeting Iranian President Masoud Pezeshkian. Reports indicate US and Iranian officials held a “productive three-hour meeting” in New York. While Iran may be willing to reopen the Strait of Hormuz within seven days if US military pressure is eased, the US administration has also decided not to proceed with bombings against Houthi rebels at this time. Despite these signals, regional instability persists, including Houthi attacks on Saudi interests and production impacts in Libya due to a valve shutdown on the Sharara crude pipeline. ## Claims - Brent crude fell by 2.08% to $101.71 per barrel.
