What happened

AI stocks initially rose due to investor enthusiasm but faced pressure as Treasury yields increased. The selloff in Treasuries highlighted concerns about higher interest rates.

Why it mattersRising yields can increase borrowing costs and reduce the attractiveness of stocks, especially those with high valuations like AI companies.

Market context The market is grappling with the dual forces of enthusiasm for AI and the reality of rising interest rates, which impact equity valuations.

Already priced in? Investors anticipated some impact from rising yields, but the extent of the selloff was unexpected.

How it spreads

Each step below is caused by the step above it. The first effect is obvious and already reflected in prices. The ones after it usually are not.

1 The cost of money strong

Moves government bond yields, which set the baseline return every other investment is judged against. When that baseline moves, everything reprices.

  1. Treasury yields rise, making borrowing more expensive. The selloff in Treasuries drives yields higher, increasing the discount rate applied to future cash flows.
  2. Higher yields make stocks less attractive. As the risk-free rate rises, the present value of future earnings declines, especially for growth stocks.

2 What central banks do next moderate

Changes how likely it is that central banks cut or raise interest rates, and how quickly.

  1. Central banks may delay rate cuts. Rising yields could lead central banks to maintain higher rates to control inflation.
  2. Delayed rate cuts keep borrowing costs high. If central banks hold off on rate cuts, it sustains higher borrowing costs for businesses.
