The trajectory of US Treasury bonds in 2026 is remarkable: the 10-year Treasury yield has risen from a low of 3.95% in February to a high of 5.35% in October, a surge of 140 basis points, exceeding the 137 basis points seen during the "treasury tightening panic" of 2013. Analysts believe that this level of long-term interest rate repricing is sufficient to have a systemic impact on global asset prices.
The 2013 "treasury tightening panic" was triggered by the Federal Reserve signaling a reduction in QE bond purchases. The market suddenly realized that ultra-loose liquidity would not last forever, leading to a sell-off of US Treasuries and a rapid rise in yields. However, the current situation is more complex, including inflationary and oil price pressures, the possibility of the Federal Reserve maintaining high interest rates for a longer period, as well as factors such as fiscal deficits, large-scale government bond supply, and rising term premiums.
Although the drivers differ, the market transmission mechanism is very similar: the surge in the 10-year Treasury yield is equivalent to a sudden increase of approximately 140 basis points in the most important "risk-free discount rate" in the US and even globally. All assets relying on long-term financing and forward cash flow valuations must be repriced. For stocks, a higher discount rate directly depresses the fair value of growth stocks, especially overvalued technology stocks. For companies, the financing costs of corporate bonds, project financing, mergers and acquisitions, and long-term capital expenditures such as data centers rise simultaneously. For the US real estate market, rising long-term Treasury yields typically keep mortgage rates high. For the US government itself, it means increasingly higher interest costs from new debt issuance and the rollover of old debt.
More importantly, US Treasury bonds are the pricing anchor of the global financial system. A significant rise in US long-term interest rates often increases the attractiveness of dollar assets, causing global capital to flow back to the US, thus putting pressure on emerging market exchange rates, capital flows, and local currency bonds. Other countries, even without a deterioration in their economic fundamentals, may be forced to bear higher market interest rates.
However, the biggest difference from 2013 is that in 2013, the market was primarily repricing "when the Fed will reduce easing," while in 2026, it's more like a repricing of "whether the central level of long-term US interest rates has already risen."
If the latter holds true, the impact could be more lasting than a short-term “debt tightening panic”, because even if the Fed stops raising interest rates in the future, fiscal supply, term premium, real interest rates and inflation risks could still keep 10-year yields at a high level.
