Treasury Yields Soar to Highest Level Since 2007 Amid AI Boom and Tight Policy

The 10-year Treasury yield climbed to 5.25% on Monday, its highest level since 2007, as investors absorbed a combination of tight Federal Reserve policy, rising energy prices, heavy government borrowing, and an AI investment boom.

Even the short end of the curve joined in the selloff, with the two-year yield rising about 8 basis points to 4.93%. However, it's the longer-term yields that are more consequential, as they feed through to mortgages, corporate financing, and the discount rates investors apply to stocks.

Federal Reserve Chair Kevin Warsh helped set the stage for this move with a quarter-point rate hike earlier this month. The Fed raised its target rate for the first time in three years, citing stronger economic data that left inflation as the central problem confronting policymakers.

Macquarie strategists Thierry Wizman and Gareth Berry argue that higher yields don't necessarily indicate an economy in trouble; they can partly reflect stronger growth, rising wages, and heavy demand for investment capital. However, they warn of the danger of rapidly rising yields exposing companies or sectors that accumulated too much leverage when money was cheap.
