**Christopher Wood, global head of equity strategy at Jefferies, has issued a stark warning that the 10-year Treasury yield crossing 5% represents a near-term risk for equity markets, with a move above this level serving as the obvious trigger point for a stock market correction. According to Business Standard, the US 10-year treasury yield has climbed 3 basis points to 4.81% on Wednesday, up from 3.8% on February 27, 2026, while the 2-year treasury yield has climbed 5 basis points to 4.41%. The 10-year Treasury yield has climbed more than 80 basis points since the beginning of March, reaching 4.79% late Tuesday and its highest level since January 2025, as reported by Reuters. Wood warns that if foreigners have the potential to sell a lot of Treasuries, they also have the potential to sell a lot of US equities, noting that foreigners own US equities because of the hot artificial intelligence story, but the opposite is the case with US Treasury bonds that have been in a brutal bear market since March 2020. Investors at this point should treat the 5% level as the reality rather than a hypothesis, because the US 10-year is already at 4.81% and the market is trading the last 19 basis points in advance, as noted by Harshal Dasani, Business Head at INVasset PMS. The near-term technical outlook for Indian markets has turned weak, with the 23,800 level on the Nifty to watch out for on the downside, as noted by Ponmudi R, CEO of Enrich Money.
US stock investors are increasingly focused on rising Treasury yields as a potential threat to Wall Street's record-setting rally, with the benchmark 10-year yield approaching a level that could put greater pressure on equity valuations and borrowing costs. According to Reuters, the S&P 500 remains up more than 11% in 2026 and was only about 2% below its August 13 record close after Tuesday's decline, despite the rising yield environment. Investors have so far been able to look past the increase in yields because of strong corporate earnings and optimism surrounding the U.S. economy, but with the second-quarter earnings season largely behind them, macroeconomic factors could have a greater influence on markets. The 10-year Treasury yield last crossed 5% in October 2023, a period that coincided with broad weakness in U.S. stocks, and a sustained move above that threshold could encourage investors to shift more money toward bonds while raising financing costs for companies.
US tech giants are flooding the eurozone bond market to fund huge AI investments, potentially crowding out other borrowers and raising credit risks, according to a European Central Bank blog post. Tech firms such as Google, Amazon and Microsoft, often referred to as hyperscalers, could spend as much as $1 trillion on AI-related investments by 2028, forcing them to tap debt markets around the world. The firms have about €40 billion ($46 billion) of bonds outstanding in the euro zone, a relatively small share of the market, but account for nearly 10% of gross new issuance. Amazon and Alphabet have been the largest corporate issuers in the euro zone bond market this year, as reported by CNBC TV18. "U.S. big tech companies could push up borrowing costs for all sectors as they accumulate debt and account for a growing share of bond markets, with a potential spillover to the sovereign and supranational segment of the bond market," the ECB blog stated. The volume of new debt issued by big tech firms could test investor appetite, while expectations of even greater bond supply may amplify this effect, potentially lifting borrowing costs across the market.
Long-term US Treasury yields are likely to remain elevated as persistent inflation concerns, rising government and corporate debt issuance, and a shifting investor base put upward pressure on borrowing costs. According to The Economic Times, the changing Treasury market dynamics could limit policymakers' ability to bring down long-term yields, with U.S. Treasury Secretary Scott Bessent seeking ways to bring down long-term borrowing costs but investors saying structural changes in the bond market could limit the government's ability to influence yields. Investors have increasingly demanded a higher term premium as concerns over inflation, government borrowing and the future supply of debt have intensified, with the term premium becoming an important driver of long-term Treasury yields. The composition of Treasury buyers has shifted toward investors who are more sensitive to prices and therefore more likely to demand higher yields, making Treasury prices more sensitive to changes in supply and demand.
A global government bond selloff intensified on Tuesday, pushing yields across major economies to their highest levels in years as renewed U.S.-Iran tensions drove oil prices higher and fanned inflation fears. According to The Wall Street Journal, the 10-year U.S. Treasury yield advanced 3 basis points, settling at 4.788% — a level not reached since January 14, 2025. The 30-year Treasury yield ended the session at 5.272%, a gain of more than 2 basis points, while the 2-year note moved up by more than 1 basis point to reach 4.362%. Bond markets beyond the U.S. also came under significant pressure, with the 10-year Japanese government bond yield crossing 3% for the first time since 1996, as reported by The New York Times. The 10-year German Bund yield reached 3.364%, a level last seen in 2011, and U.K. gilt yields climbed sharply, with the 10-year reaching 5.254% — a level not touched since 2008. As reported by Reuters, the 30-year yield has reached its highest mark in nearly two decades, with investors pointing to mounting government borrowing that markets must absorb, resilient economic growth, inflation risks from Middle East energy disruptions and potential for the Fed to keep rates higher as key drivers behind the move.
Five of the biggest AI hyperscalers — Alphabet, Amazon, Meta, Microsoft and Oracle — have issued $220 billion of debt already this year as they fund investments in data centres and models, according to LSEG data, which is more than double last year's total figure. This surge in bond sales to fund AI investments is another factor pushing up bond yields, with borrowing for AI investments helping push global corporate bond issuance to a record $4.9 trillion so far in 2026, up 14% from this point a year ago. Analysts point to the laws of supply and demand: if there is a jump in need for borrowing, lenders can charge higher interest rates, pushing up yields. The resulting competition has helped push the yield spread between high-quality corporate bonds and Treasuries toward historically narrow levels, with corporate bonds carrying default risk unlike U.S. government securities, but investors appearing increasingly comfortable with the credit quality of large companies accessing long-term debt markets. The ECB blog's authors also argued that the relatively high credit ratings assigned to big tech debt may prove overly optimistic, stating "The way rating agencies approach this sector may be based on assumptions on future revenue growth and leverage which may not stand the test of time, heightening the vulnerability to mispricing of credit risk."
Despite the current volatility, analysts suggest the correct expectation is compression concentrated in the longest-duration, most expensive pockets, richly priced consumer names, new-age technology and the stretched end of small and midcaps, while reasonably valued domestic cash generators absorb it better, according to Harshal Dasani from INVasset PMS. That is a rotation and a valuation reset, not a crash, and the distinction is the whole answer. A higher global risk-free rate compresses the price-to-earnings ratio that any equity market can defend, but it does not reduce what Indian companies earn. The transmission into Indian equities runs through the multiple, not through earnings, as noted by Harshal Dasani. Even if the market corrects towards 23,000 Nifty, analysts advise accumulating quality stocks at lower levels, with the market trading near its historical valuation of 18x indicating valuation is not stretched. S&P 500 valuations have already eased due to strong corporate earnings, with concerns over the sustainability of AI-related spending and broader economic outlook contributing to a more cautious investor approach. Investors expect higher bond yields to place a ceiling on further price-to-earnings multiple expansion unless earnings growth continues to significantly outperform expectations.
