Overview

  • U.S. and Iranian air strikes near the Strait of Hormuz renewed geopolitical risk and sent crude prices higher, prompting investors to push long-term Treasury yields up.
  • The 10-year Treasury yield moved higher in early trading as investors priced in greater inflation and risk, following recent spikes that took the 10-year and 30-year to multi-year highs in late May.
  • Higher long-term yields raise rates on mortgages, auto loans and corporate borrowing because Treasury yields serve as a benchmark for those prices.
  • A large near-term refinancing load for the government and a reported Pentagon funding request for war-related spending increase the budget’s exposure to higher interest costs when debt is rolled over.
  • Federal Reserve officials have signaled they could keep policy tighter if inflation stays elevated and former Fed chair Jerome Powell warned political pressure on the central bank could undermine its independence, a dynamic that could affect future rate paths and market confidence.
