Brent crude settled near $100.69 on Monday, jumping roughly 7% after a series of tanker attacks in the Red Sea rattled energy markets. The spike in oil sent ripples across Wall Street: the S&P 500 closed at 7,408.30, down 1.21%, while the Nasdaq Composite fell 2.15% as investors reassessed the outlook for growth stocks amid rising energy costs.
Why oil spiked
The attacks on tankers in the Red Sea — a critical chokepoint for global oil shipments — stoked fears of supply disruptions. Traders bid up crude as the risk premium on Middle East supply routes widened. The one-day move pushed Brent above $100 for the first time in months, though it settled just below that psychological level.
Tech stocks take a hit
Higher oil prices tend to lift headline inflation expectations, which in turn firms up uncertainty around the path of interest rates. Growth stocks behave like long-duration assets: their future cash flows get discounted more heavily when rates rise, hitting high-multiple names hardest. Tesla dropped roughly 14–15% after its earnings update and guidance disappointed. Alphabet slid about 7% on its own earnings report. The sell-off was broad, with investors questioning the payback periods on massive AI capital expenditures.
Energy and defensives gain
Not all sectors suffered. Energy stocks saw relative bids as the oil spike directly benefits producers. Select defensive sectors also attracted money as traders rotated out of high-growth names. The divergence between energy and tech was stark — a classic flight to near-term cash flows over long-duration bets.
What the oil move means for rates
A sustained rise in crude can push headline inflation higher, complicating the Federal Reserve's timeline for rate cuts. Markets are now pricing in more uncertainty around the path of monetary policy. If oil stays elevated, the rate path could stay firmer for longer, which would keep pressure on growth stocks.
The next big test comes with the release of the Consumer Price Index later this month, followed by the Fed's rate decision. Until then, the tug-of-war between energy-driven inflation and tech valuations will likely continue.
