US 10-Year Treasury Yield Hits 5.18% on September 24, Highest Since 2007

The US 10-year Treasury yield climbed to 5.18% on September 24, its highest level since 2007, as real interest rates surged 43 basis points in less than a month. The move reflects rising capital costs across the global economy, with BNP Paribas warning yields could reach 5.6% within months. For Hong Kong investors, higher US rates typically strengthen the dollar and pressure emerging market assets.

Why the 10-year yield jumped so sharply

From August 28 to September 24, the 10-year yield rose 45 basis points. About 96% of that increase, or 43 basis points, came from rising real interest rates rather than inflation expectations. The 10-year breakeven inflation rate moved only 2 basis points, signaling that markets see inflation as stable. Strong US economic data, including manufacturing and services PMI beats, combined with higher oil prices above $105 a barrel and a weaker Treasury auction, all pushed yields higher.

Real rates are the real story

The 10-year real yield climbed from 2.42% to 2.85% in the same period. This matters because real rates determine the true cost of borrowing after inflation. Real yields rising 43 basis points means companies and governments face steeper financing costs. The S&P 500 absorbed this repricing with minimal daily swings, averaging just 0.57% moves per day, while the VIX stayed below 15 on September 25.

Credit stress is widening, especially for weak borrowers

High-yield bond spreads expanded 20 basis points from late August, but bonds rated CCC or lower saw spreads widen 86 basis points. BNP Paribas predicts the 30-year yield will reach 5.6% as rising government debt and higher Fed rates increase Treasury supply. The firm warns that if the Fed raises rates four times as markets expect, the US Treasury’s annual interest payments could jump HK$186 billion in year one and HK$269 billion by year two, eroding fiscal space.

What this means for investors

Higher real yields make bonds more attractive relative to stocks, especially for income-focused portfolios. The 30-year yield already sits at 5.49%, its highest since 2004. Mortgage rates have climbed above 7%, pressuring housing demand. For Hong Kong investors, rising US rates typically support the Hong Kong dollar peg and lift returns on US dollar deposits, but they also weigh on tech and growth stocks that depend on cheap capital.

Final Thoughts

US Treasury yields are repricing higher on real rate pressure, not inflation fears. With credit stress concentrated in weaker borrowers and the Fed potentially raising rates further, bond prices face headwinds. Hong Kong investors should monitor US rate expectations closely, as they drive capital flows and currency moves across Asia.
