The 30-year Treasury yield has hit a 19-year high, and some strategists predict further upward pressure. This surge is not solely due to domestic factors but is influenced by global economic dynamics. The recent jump in Treasury yields was triggered by Japan's weaker-than-expected economic growth and a hotter GDP deflator, causing a ripple effect in U.S. markets. If yields in other major developed markets continue to climb, investors may demand higher returns on U.S. government debt, adding to the upward pressure. BMO strategists highlight fiscal concerns across the U.S., Japan, U.K., and Europe as a potential factor behind the weakness in long-dated bonds. Even if U.S. economic data softens, a global repricing of long-term borrowing costs could keep Treasury yields elevated.
One significant risk is the U.S. economy's resilience. Markets are currently pricing a combination of strong growth and record-high equities, limited by central bank tightening and contained commodity supply shocks. However, this combination may be unsustainable. Strong growth and loose financial conditions can lead to higher demand and faster rate hikes, pushing inflation and bond yields even higher. Deutsche Bank's macro strategist, Henry Allen, argues that this scenario could force the Federal Reserve to raise rates more than anticipated.
Another factor is the term premium, which is specific to longer-dated bonds. Investors may demand greater compensation for lending to the U.S. government for decades. Heavy Treasury issuance and persistent inflation concerns are pressure points. BMO notes that the latest 30-year auction cleared at its highest yield since 2001, indicating less robust demand for long-duration debt. A renewed commodity shock would exacerbate the situation, impacting both growth and inflation and potentially hitting equities and bonds simultaneously. As Deutsche Bank states, the current market pricing leaves little margin for error, making long-dated Treasurys vulnerable from multiple directions.
