The main story on the morning of September 1 is the tension between the energy shock and risk appetite: the renewed escalation of the U.S.-Iran conflict pushed oil higher and equity closes lower. August gains were not erased; the key question is whether the shock becomes persistent inflation or a one-day flight from risk.

The real test is not oil itself but the rates and breadth channels. At the August 31 close, the S&P 500 fell to 7,686.14 and the Nasdaq to 26,370.89 while Brent closed at $90.49; the official 10-year U.S. Treasury yield was 4.75% and the 30-year yield was 5.25%. This mix asks whether high-tech valuations can absorb oil and bond selling at the same time.

Oil and long-term yields are again creating pressure in the same direction. Semiconductors and some software stocks, by contrast, look better than the indexes; small companies and Turkish equities are more fragile. This split shows that panic has not spread across the whole market, but relief has not been confirmed either.

Key takeaways

  • Tension around Hormuz is pushing oil higher and stocks lower; Tunç Şatıroğlu (@tuncsatiroglu) emphasizes that it is too early to say the risk has passed until oil and long-term Treasury yields ease together.
  • Indexes have held their August gains, but the S&P 500 and Nasdaq remain below critical recovery levels; the first test will be how many stocks the decline reaches.
  • The prospect of a rebound in gold and silver remains, but as in Tunç Şatıroğlu's commentary, oil, rates and metal moves need to calm together before new buying can be considered.

What happened?

  • According to the Associated Press, the U.S. attacked Iranian rocket launchers around the Strait of Hormuz on August 31; Iran's response and the rising tension lifted Brent 2.7% to a $90.49 close. A wider conflict is not confirmed, but the energy-supply risk premium remains alive.
  • Bloomberg Television's Balance of Power said that oil rose after the weekend attacks and expectations that Hormuz would reopen in the near term weakened. How quickly Venezuela's oil arrangement could affect prices remains an important question.
  • Yahoo Finance's Market Domination stressed that rising long-term Treasury yields are compressing equity valuations, while the debate over AI demand is separating companies. The AI theme needs to be read through chip and software participation, not the index level alone.
  • CNBC's month-end wrap said that despite August 31's down day, three U.S. indexes finished August with gains. Mad Money also emphasized tracking oil, rates and company outlook together.

Market levels

Global risk and oil

  • Brent was at $91.56 on the latest screen; staying above the $90 support and pressure line keeps energy-driven inflation risk alive, while $95 is watched as resistance and a risk boundary.

US indices

  • At the latest close, the S&P 500 fell to 7,686.14 and remained below 7,700 support. Reclaiming 7,775 would repair the close, while 7,850 resistance would show that the advance has regained strength.
  • The Nasdaq was at 26,370.89 at the latest close; 26,250 is support, 26,650 the first recovery level and 27,000 resistance. Until 26,650 is reached, it is too early to assume a broad turn in technology.

Themes and ETFs

  • QQQ, which tracks the Nasdaq 100, was at $716.76 at the latest close; $710 is support, $720 the first recovery level and $725 resistance. Above $725 would give a cleaner sign that technology leadership is strengthening again.
  • SMH, the semiconductor ETF, was at $556.63 above $550 support but below the $560 recovery level; the $570 resistance area is being watched. Until the chip group clears this threshold, it cannot carry index resistance on its own.
  • NVIDIA ($NVDA) was at $220.78, just above the $220 recovery level; $215 support is holding, but the move cannot be treated as broad technology confirmation until the $225 resistance area is cleared.
  • IGV, the software-company ETF, was at $109.98 at the latest close; $107 is support, $110 the recovery level and $114 the resistance area. Software holding $110 could show that AI spending is not concentrated in a few large chip companies.
  • IWM, the ETF tracking small U.S. companies, was at $293.93, below $295 support; small-company participation remains weak until the $300 recovery level and $305 resistance area are reclaimed.
  • TLT was at $82.52, close to $82 support; its recovery to $84 and the $86 resistance area will show whether long-term rate pressure is easing. A move below $82 would signal that bond selling is deepening.

Crypto and precious metals

  • GLD, the gold ETF, was at $408.42 at the latest close; $405 is support, $415 the recovery level and $420 resistance. SLV was at $60.13, above $58 support but below the $62 recovery level and still well short of $65 resistance; relief does not yet look complete in either metal.
  • In the latest morning trade, BTC was at $78,820.46, ETH at $2,475.433 and XRP at $1.38572. BTC support is $75,000 and resistance $82,000; ETH support is $2,400 and resistance $2,600; XRP support is $1.35 and resistance $1.50. Until the recovery thresholds are cleared, crypto should not be treated as confirmation of equity breadth.

Turkey

  • The BIST 100 was at 14,334.06 on the latest screen, below 14,500 support; 14,700 is the recovery level and 15,000 resistance. USD/TRY was at 48.2774; if the exchange rate settles above 48.50, oil's inflation channel will become heavier.

Red flags

  • If Brent rises above $95 or the 10-year U.S. Treasury yield exceeds 4.90%, the oil shock may be priced as persistent inflation pressure rather than a temporary move.
  • If the S&P 500 remains below 7,700 while the Nasdaq loses 26,250 and QQQ loses $710, narrowing technology leadership could turn into a broad risk-reduction wave.
  • New attacks around Hormuz or a verified development showing that commercial passage is materially disrupted could lift the existing oil and rate framework again.

My analysis

The day's pricing looks to me less like a full trend reversal than a renewed test of the market's weak links by the energy shock. The S&P 500 losing 7,700 support matters, but SMH and NVIDIA holding their recovery thresholds show that the selloff has not yet broken the entire AI theme. IWM's slight slip below support warns that the advance has not broadened to the base.

If Treasury yields and oil rise together, August's index gains will not provide confidence on their own. If oil returns toward $90, the 10-year yield approaches 4.60% support and the Nasdaq reclaims 26,650, the chance that this remains a one-day shock will increase. The sequence to watch is whether these three conditions form together.

The "labor-market" calendar will test this framework quickly. The Waller and Barr speeches will shape rate expectations, while JOLTS and Friday's employment report will show how much of the oil shock the economy can absorb. The result today is not that the selling is over; it is that the chain between oil, rates and market breadth remains unresolved.
