Shares shifted as reports emerged Wednesday that Washington delivered a 15-point peace plan to Tehran, igniting the sharpest risk-on move in days and pushing VOO up 1% to $608.64. S&P 500 futures rose 0.8% after the reports, while Brent fell 5% to below $100 a barrel — even as the Strait of Hormuz remained effectively shut. For VOO holders — who own a slice of all 500 of America's largest companies — the question is whether diplomatic optimism can stick long enough to reverse a brutal month.
• Oil Below $100 Gives Stocks Room to Breathe — For Now
Brent fell 5.10% to $99.16 a barrel and WTI dropped 4.27% to $88.41 amid ceasefire hopes. That matters directly to VOO because the war with Iran has sent energy prices soaring, raising concerns about inflation and complicating the outlook for central banks globally, while uncertainty about the conflict's duration is dimming the outlook for stocks.
Goldman Sachs nudged its recession probability to 30%, noting that higher oil prices will add roughly 1% to global headline inflation and subtract 0.4% from global GDP growth.
• A $3.2 Trillion Hole That One Headline Can't Fill
The S&P 500 closed at its lowest point of 2026 last week, erasing $3.2 trillion in market capitalization since the onset of the Iran war.
Since the war started, the S&P 500 has fallen 5.41%, the Nasdaq has lost 4.5%, and the Dow has fallen 6.95%. Today's bounce reclaims just a fraction of that damage. The current episode has produced a peak-to-trough decline of just 4%, yet oil prices have already risen 68% from their pre-war level — comparable to the Ukraine war shock that ultimately delivered a 25% drawdown.
• Tehran's Denials Leave the Rally on Shaky Ground
Iranian officials denied that any talks had taken place, with parliament speaker Ghalibaf accusing Trump of trying to "manipulate the financial and oil markets."
Analysts at Nissan Securities noted that uncertainty surrounding the outcome of negotiations remains high, limiting the extent of the oil selloff. The Strait of Hormuz — the shipping lane carrying a fifth of global oil — remains largely closed, meaning the supply crisis that drives inflation fears has not actually eased.
• History Warns the Worst May Not Be Over
During the four major oil supply shocks of recent decades, the S&P 500 declined by a median of 12% alongside rising prices, and the median peak-to-trough decline across those episodes was 23%. If the Hormuz blockade drags on, Goldman puts the S&P 500's downside at 5,400 — a 20% decline from recent levels. VOO shareholders should treat today's pop as a headline-driven relief rally, not a signal that the worst is behind them.
