Signal
The escalating conflict with Iran is creating cascading effects across global financial markets, with three critical developments emerging today. First, the effective closure of the Strait of Hormuz has collapsed legitimate oil tanker traffic by 90%, though a shadow fleet continues operations. Second, this geopolitical tension is driving mortgage rates to their highest levels since August 2025, indicating significant stress in credit markets. Third, the $1 billion daily cost of the war is straining U.S. fiscal positions while simultaneously driving crypto assets like Bitcoin to outperform traditional safe havens such as gold. This confluence of events suggests we're entering a period of heightened market volatility where traditional risk metrics and correlations may not hold. Banking professionals should be particularly attentive to the emerging pattern of capital flight to alternative assets and the potential for significant disruption in traditional lending markets.
