US indices test 50-day support as 10-year yield nears 4.73%
All three major US equity benchmarks are testing their 50-day exponential moving averages in pre-market trading as rising Treasury yields pressure valuations.
The S&P 500, Nasdaq 100 and Dow Jones 30 are testing their 50-day exponential moving averages as the 10-year Treasury yield holds near 4.73%, a level that has repriced equity valuations across growth and technology names.
"Higher yields are here to stay for a reason," said Wei Li, global chief investment strategist at BlackRock Investment Institute.
The 30-year Treasury yield sits at 5.21%, near its 19-year high of 5.30%, while Brent crude has climbed above $90 a barrel after renewed US-Iran tensions. Fed Chair Kevin Warsh reiterated the central bank's commitment to fighting inflation, and markets have raised the probability of a September rate increase. German 10-year yields have hit a 15-year high near 3.25%, and Japanese 10-year yields are nearing 3% for the first time since the mid-1990s.
A break below the 50-day EMAs could trigger automated stop-loss selling across all three benchmarks, accelerating the downside. The next test is the US August payrolls report due Sept. 4, which will shape whether the Fed moves in September.
The synchronized weakness across the three benchmarks points to a macro-driven repricing rather than sector-specific stress. Higher discount rates reduce the present value of future earnings, a dynamic that hits growth and technology stocks hardest because a greater share of their expected profits sits years out. More than 80 percent of the global bond universe now yields above 4 percent, according to BlackRock's analysis of LSEG data, sharpening the competition between equities and yield-bearing assets.
Yields Reshape the Equity-Bond Trade-Off
The equity-bond trade-off has shifted since the global rate reset began in 2021. Global equities have returned about 10 percent more than three-month Treasury bills so far in 2026, while global government bonds have returned about 3 percent less, BlackRock data show. Yet rising yields have turned long-duration bonds into a less reliable portfolio ballast, pushing investors toward shorter maturities where income is more meaningful relative to duration risk.
The AI trade has been a notable exception to the rate pressure. The Nasdaq gained 1 percent after Nvidia's latest blowout quarter and sits roughly 3 percent below its all-time high, even as yields climbed. Li argues higher rates need not derail the AI equity case if investment keeps generating durable returns, but the firm favors segments tied to scarce bottlenecks — power, chips and data center infrastructure — over downstream model makers.
If the indices close below their 50-day EMAs, technical traders could read it as confirmation of a broader downtrend. The 10-year yield's path depends on inflation, Treasury issuance and oil prices; sustained crude above $90 would add to price pressures and keep the Fed on hold. Treasury Secretary Scott Bessent has pushed back against concerns that current debt-market strains represent a systemic threat, distinguishing elevated yields from a market-functioning crisis.
For investors, the critical variables are inflation, Federal Reserve policy, Treasury issuance and oil. If inflation stays sticky and government borrowing remains elevated, yields could stay higher for longer, keeping pressure on expensive equity valuations through the rest of 2026.
