Geopolitical Context Negotiations between the U.

S. and Iran have faced challenges. The first round of talks in Islamabad stalled last weekend. S. announced a blockade of the Strait of Hormuz, a key trade route that typically carries about 20% of global oil supply.

S. sailors, Marines, and airmen are enforcing the blockade with over a dozen warships and dozens of aircraft. The blockade has reduced traffic through the strait to minimal levels. S. announcement on April 7 indicated a two-week ceasefire agreement with Iran would depend on the strait's full reopening.

Economic Implications Citadel CEO Ken Griffin stated that a prolonged disruption in the Strait of Hormuz could lead the global economy toward a recession.

Experts reported to CNBC that Europe's airline industry faces a potential systemic jet fuel shortage in the coming weeks if the blockade continues. Such a shortage could result in hundreds of flight cancellations. The situation has heightened tensions among major powers.

Corporate Developments Meta and Broadcom announced an extended partnership to develop Meta's custom in-house AI accelerators through 2029.
