Dow falls 450 points as losses accelerate following a 19-year high in the 10-year Treasury yield: Live updates

The Dow closed 450 points lower Monday as the 10-year Treasury yield hit a 19-year high, extending pressure on equities from rising bond yields and oil prices. Tuesday's session opened with further losses as traders positioned ahead of this week's Federal Reserve policy decision.

The Treasury yield surge to levels not seen since 2004 is repricing risk across asset classes, pulling capital from equities into fixed income. Higher borrowing costs threaten corporate margins and consumer spending, two pillars supporting the current earnings environment. Oil's continued climb adds inflationary pressure that could force the Fed's hand on rates.

The central bank's Wednesday announcement carries heightened weight as markets debate whether recent inflation prints justify another rate hike or signal a pause. The dual headwind of yields and energy costs has already erased gains in rate-sensitive sectors, with financials and technology bearing the brunt of Monday's selloff.
