US 10-year Treasury yield climbs to 5.342%, reaching highest level since 2002

Surge to multi-decade peaks

The yield on the benchmark 10-year US Treasury note climbed to 5.342% on Thursday, surpassing its 2007 peak to reach its highest level since early 2002. The move extended a persistent selloff in sovereign debt, with benchmark yields touching two-decade highs for a seventh consecutive trading session. Before a pullback in energy prices helped stabilize trading just below 5.28%, intraday yields had previously reached 5.31% and 5.33% across international trading desks. In the longer-dated maturities, the 30-year US Treasury yield reached 5.65% on Thursday morning, following a peak of 5.62% on Wednesday, marking its highest reading since 2002. Over the full September quarter, the 10-year note recorded an 87.1 basis point yield increase, representing the steepest quarterly rise since 1994 according to data compiled by LSEG.

Macroeconomic drivers and energy inflation

A combination of persistent inflation, heavy government borrowing, and resilient macroeconomic growth has kept policy interest-rate expectations elevated. Crude oil traded near $100 per barrel amid ongoing geopolitical tensions and the Iran conflict, contributing directly to sticky headline inflation figures across global economies. Concurrently, large fiscal deficits and continuous sovereign bond issuance by the United States Treasury have expanded debt supply at a time when central bank rate hikes remain in effect. Economic activity has also drawn support from large-scale corporate spending, particularly capital investments directed toward artificial intelligence development and data centre construction. These operational investments have lifted forward projections for economic expansion and elevated forecasts for where short-term benchmark rates will ultimately settle.

Global bond market reallocation

The selloff in fixed income has extended across global sovereign debt markets, concluding the third quarter of 2026 as the worst period for government bonds since 2024. In Japan, sovereign yields recorded a fifth consecutive quarter of double-digit basis point gains as domestic inflation established a foothold after decades of deflationary pressure. Because bond prices fall when yields rise, institutional investors across global financial centres have adjusted their portfolio positioning to account for higher baseline yields. Mark Malek, chief investment officer at Siebert Financial, noted that higher yields have fundamentally altered the balance of risk and return in asset allocation.

Investors no longer need to venture out on the risk spectrum simply to generate meaningful nominal income.

Economic consequences for borrowers and states

The steep climb in Treasury yields has direct implications for financing costs across consumer, corporate, and sovereign borrowing channels. Because the 10-year Treasury serves as the standard reference rate for private lending, US real estate mortgage rates have climbed above 7.0%. Consumer financing terms for automobile loans and credit cards have similarly tightened alongside higher benchmark borrowing rates. For corporations, elevated market rates increase the cost of refinancing existing debt maturities and funding new capital investments. Furthermore, rising sovereign yields require governments to allocate larger shares of national tax revenues toward debt servicing payments, leaving fewer public funds available for social programmes and infrastructure development.
