Wall Street is staring down its worst sustained sell-off in nearly a year as oil topping $100 a barrel reignites stagflation fears, the VIX fear gauge breaches 30, and the US-Israel war on Iran shows no sign of ending.
Just over a week into the US-Israel war on Iran, Wall Street has begun pricing in something it initially hoped to avoid: a prolonged conflict. Dow futures fell as much as 1,000 points in pre-market trading on 9 March before recovering partially to a loss of around 595 points, or 1.25%, as investors absorbed the weekend's developments. S&P 500 futures lost 1.1% and Nasdaq 100 futures dropped 1.2%. The Cboe Volatility Index, known as Wall Street's fear gauge, topped 30 for the first time since the tariff-driven market sell-off of April 2025, signalling that investors are aggressively seeking protection against further losses.
The catalyst is unmistakable. West Texas Intermediate crude jumped 13% to $102.67 per barrel, crossing $100 for the first time since 2022, while Brent surged 9.84% to $101.81. US crude had already gained 35% the previous week, its largest single-week advance since futures trading began in 1983. With oil at these levels, the market has begun to draw uncomfortable parallels to the 1970s, when oil shocks triggered a prolonged period of stagflation that damaged equities for years.
Iran Names New Supreme Leader After Khamenei Killed in US-Israel StrikeThe word dominating trading floors and research notes this week is stagflation, a portmanteau of stagnation and inflation describing the toxic combination of rising prices and slowing growth that leaves central banks with no good options. Ed Yardeni, president and chief investment strategist at Yardeni Research, wrote that he cannot rule out a bear market if investors start to anticipate a stagflationary 1970s Redux scenario. He added that if the oil shock persists, the Federal Reserve's dual mandate would be stuck between the increasing risk of higher inflation and rising unemployment.
The concern is well-founded. Inflation was already elevated entering 2026, with tariff-driven price pressures keeping the Fed cautious about cutting rates. Now, oil prices above $100 per barrel are poised to push headline inflation materially higher. At the same time, higher fuel costs squeeze consumer spending, raise business costs and slow economic activity, creating exactly the growth drag that might otherwise call for rate cuts. The Fed's next meeting will be watched with unusual intensity for any signal about how it intends to navigate this bind.
The market's response to the conflict has not been uniformly negative. Energy stocks have surged as oil prices climbed, with US crude posting a 35% weekly gain that is unprecedented in the history of the futures contract. Defence stocks have also outperformed, buoyed by expectations of increased military spending and the continuation of US and Israeli operations. Gold, which has topped $5,000 per ounce for the first time, reflects a powerful safe-haven bid as investors move money out of equities and into assets that historically hold value during geopolitical crises.
The damage elsewhere has been significant. Financials and industrials led the declines as investors priced in an economic slowdown. Airline stocks were among the worst performers, with a popular airline-tracking ETF recording its worst single day since April 2025 on 5 March. The aviation sector faces a triple blow: sharply higher jet fuel costs, cancelled routes across closed Middle East airspace, and weakening passenger demand. Consumer discretionary stocks have also suffered as the market prices in the impact of higher fuel and energy bills on household spending.

Before the Iran conflict, the Federal Reserve was already navigating a difficult environment. Tariff-driven price pressures from the Trump administration's trade policy were keeping inflation above target, limiting the Fed's ability to cut rates even as growth slowed in late 2025. The oil shock now layered on top of that picture has made the Fed's task considerably harder. If inflation climbs toward 4 or 5%, the Fed faces pressure to tighten. But if economic growth deteriorates sharply, tightening could tip the economy into recession.
Treasury yields rising to 4.198% on the 10-year note reflects this bind directly. Investors are selling bonds because they expect inflation, which pushes yields higher. Higher yields in turn put pressure on equity valuations, particularly for growth and technology stocks whose future earnings are discounted at a higher rate. This dual pressure, falling equities and rising yields, is precisely the dynamic that characterised the most painful periods of the 2022 market sell-off.
Iran Indicates Mojtaba Khamenei Will Succeed His Father as Supreme LeaderMarkets face a data-heavy week that would be consequential even without a geopolitical shock. Inflation, employment and GDP releases are all scheduled, and with WTI crude above $100, every data point carries extra weight. A hot inflation print would intensify stagflation fears and likely extend the sell-off. A weak jobs number would amplify growth concerns. A positive surprise on either front could provide a temporary floor, but analysts caution that without meaningful progress on the geopolitical situation, any relief rally is likely to be short-lived.
The appointment of Mojtaba Khamenei as Iran's new Supreme Leader, widely regarded as a hardliner, and Trump's immediate rejection of him as unacceptable, have diminished near-term hopes for de-escalation. With both sides expanding their target sets to include critical infrastructure such as desalination plants and oil storage sites, the risk of further supply disruptions remains elevated. Ed Yardeni has said his base case is still a technology-led economic boom and bull market once the war resolves, but that base case depends entirely on the conflict being resolved in weeks rather than months.
For equity investors, the calculus is clear. Until there is a credible path to de-escalation, oil prices are likely to remain elevated, inflation expectations will stay high, and the Fed will remain constrained. In that environment, the rotation out of equities into energy stocks, gold and short-duration bonds is likely to continue. The next major catalyst for markets will not come from a data release. It will come from a diplomatic development or a military outcome that changes the trajectory of the conflict itself.
