U.S. equities fell sharply yesterday as oil and Treasury yields rose; the S&P 500 fell 0.9% to 7,641.16 and the Nasdaq Composite fell 1% to 26,067.17. The market's decline as oil and yields rose shows that this was not simply a technology selloff: discount rates and consumer concerns were working together.

The Treasury's bond-buying announcement had created temporary relief; as the 10-year yield returned to about 4.71% in early Asia trading today, the real test became whether the purchases could bring long-term borrowing costs down durably. Today's labor-market data will test whether the rate relief returns.

Risk appetite recovered briefly after the Treasury move, but the August 20 picture delivered a tougher message: Brent rose, Walmart exposed consumer sensitivity and chips stayed below support levels. The line is clear: if oil and long-term yields remain elevated together, equity valuations will face a higher standard of proof even if the AI-spending story remains strong.

Key takeaways

  • The Treasury's communication about long-term purchases may temporarily lower yields by supporting bond prices; this is not a Federal Reserve decision or permanent quantitative easing.
  • The S&P 500 fell to 7,641.16, the Nasdaq Composite to 26,067.17 and the Dow Jones to 52,759.21; Brent rose 2.4% while the 10-year yield returned to about 4.71% in early Asia trading on August 21.
  • The Nasdaq 100 ETF $QQQ closed at $710.93 and the semiconductor ETF $SMH at $562.65; with the first recovery lines unreclaimed, risk appetite did not produce broad-based confirmation.
  • Bitcoin was around $75,183, Ethereum $2,357 and XRP about $1.31; crypto strength is not evidence of broad participation in equities.

What happened?

  • According to the Associated Press's August 20 close, the S&P 500 fell 66.82 points, the Dow Jones 703.84 points and the Nasdaq Composite 263.92 points; the Russell 2000 fell 1.3%.
  • The Associated Press reported that Brent rose 2.4% after the latest U.S.-Iran threat and that the previous relief in the bond market had disappeared; in its early Asia update on August 21, oil edged lower while yields remained high.
  • Walmart shares fell more than 8% on August 20; the company's U.S. comparable sales rose 2.6% in the second quarter, described as the slowest growth in six years.
  • The common framework across Bora Özkent (@boraozkent), Kanal Finans, Bloomberg Television, Yahoo Finance and CNBC was that rate relief could give technology room to breathe, but concentration in chips and the need for AI investments to prove their returns remain.

Market levels

Global risk and oil

  • Brent rose 2.4% on August 20 and stayed above the $90 threshold before edging lower in early trading on August 21. $90 is support and the first pressure line, while $95 is the main risk boundary; below $90 would bring relief, while above $95 would increase inflation and rate pressure.
  • The 10-year U.S. Treasury yield is about 4.71%; support is 4.65%, the directional line 4.70% and the main resistance and risk threshold 4.85%. Holding below 4.65% extends valuation relief, while above 4.70% narrows it.

US indices

  • The S&P 500 at 7,641.16 is below the 7,750 support and reclaim line; 7,800 is the pivot and 7,850 the next resistance. A broad-index rebound cannot be considered complete until 7,750 is reclaimed.
  • The Nasdaq 100 ETF QQQ at $710.93 is below the $725 support zone; $734.56 is first resistance and $740 the next threshold. Technology leadership cannot be considered reconfirmed until $725 is reclaimed.

Themes and ETFs

  • The semiconductor ETF SMH at $562.65 is below the $585 support zone; $600 is main resistance. Until $585 is reclaimed, there is no short-term momentum repair in the AI hardware theme.
  • The ETF that tracks small U.S. companies, $IWM, is at $297.67; the support zone is $302-$303, the pivot $305 and resistance $310. Below $302, market breadth is not offsetting the technology selloff.
  • The software-company ETF IGV at $101.91 is below the $103.70 support line and above the $101 risk area; $106.30 is first resistance. Rate sensitivity persists in software until $103.70 is reclaimed.
  • Meta at $545.83 is below the $580 support/risk line; $590 is resistance. Company-specific weakness cannot be considered over until $580 and then $590 are reclaimed.

Crypto and precious metals

  • Bitcoin is around $75,183, above the $67,000 conditional confirmation level; support is $62,000 and the next risk area $58,000. This structure is positive, but it is not broad confirmation for the technology market on its own.
  • Ethereum is around $2,357, above the $1,950 repair line, and XRP around $1.31, above the $1.07 confirmation threshold. Both moves support risk appetite, but they do not close the break in the equity base.
  • Gold ETF $GLD at $415.26 is above the $400 support line; Kanal Finans's cited spot-gold confirmation and resistance threshold of $4,425 is not on the same scale as the ETF price.
  • Silver ETF $SLV at $61.66 is above the $58 support line; unless the cited spot-silver confirmation condition of $66 is cleared, the metals move is not broad-based confirmation.

Red flags

  • If Brent stays above $90 while the 10-year Treasury yield exceeds 4.70%, valuation pressure on technology stocks will grow; above 4.85% would indicate a more severe risk regime.
  • If QQQ stays below $725, SMH below $585, IWM below $302 or IGV below $101, market participation weakens even without the selloff spreading beyond technology.
  • If the initial relief from Treasury buying fails to produce lasting demand, Walmart-like consumer signals multiply or the BLS data increases rate pressure, the rebound in growth stocks will remain a short-lived reaction.

Calendar

  • August 21, 5:00 p.m. TRT: BLS will publish the July 2026 State Employment and Unemployment data; the release will test the current balance between long-term yields and growth stocks.

My analysis

My base case is a selective rebound limited by temporary rate relief. Treasury purchases may support demand in specific maturities, but they do not remove oil-driven inflation risk or public-debt concerns. That is why the August 20 selloff shows that the Treasury move's initial effect was not sufficient on its own.

Today's decision filter is clear: relief strengthens if the 10-year yield stays below 4.65% and Brent returns to $90; if a yield above 4.70% and Brent above $90 hold at the same time, the effect of bond buying remains limited. QQQ reclaiming $725 and SMH reclaiming $585 would be the first equity-side confirmation of this thesis.
