Blockade in the Strait of Hormuz and the banking market shock: US giant bank stocks collapse
Geopolitical tensions in the Strait of Hormuz have caused oil prices to surge, leading to inflation and a crisis in the US banking sector. According to Bloomberg, Bank of America (BAC), State Street (STT), and Citigroup (C) shares dropped 18%, 14%, and 10% respectively. The Fed raised rates to 4% to combat inflation, further straining banks. The KBW index of major US banks fell 13% from its August peak, marking its longest decline since 2008.
