Shares slid broadly as Iran's flat rejection of a U.S. ceasefire proposal reignited fears of a prolonged Middle East conflict, sending crude oil surging and dragging VOO down 1.0% to $599.39 — erasing this week's gains and putting the fund back near last Friday's close of $597.94. Iran's Ceasefire Rejection Sends Oil Past $100 and Drags the S&P 500 Down — How Deep Can This Energy Shock Cut Into Earnings?
Shares slid across Wall Street as Iran flatly dismissed a U.S. 15-point ceasefire proposal, dashing hopes for a quick end to a conflict the International Energy Agency has called "the largest supply disruption in the history of the global oil market." VOO fell 1.0% to $599.39, erasing this week's gains and pushing the broad market index back toward last Friday's close of $597.94.
• Oil Has Surged 40% in a Month, and That Tax Hits Every S&P 500 Company
Oil prices have climbed around 40% since the beginning of the war, which is now in its fourth week, with the Strait of Hormuz remaining largely closed.
Brent crude now sits at $106.12, with WTI at $93.61.
The conflict has added an estimated $15–20 per barrel risk premium since hostilities began in early March. For S&P 500 companies, costlier oil means higher input costs, squeezed margins, and a consumer whose wallet is thinning at the gas pump — a direct threat to the earnings growth that underpins VOO's valuation.
• Iran's Demands Signal a Long Crisis, Not a Quick Fix
Iran's counterproposal includes reparations for the war and "exercise of sovereignty over the Strait of Hormuz" — conditions that are likely unacceptable to the White House as energy supplies worldwide remain affected.
Iran's Foreign Minister said his government "does not plan on any negotiations." Every week this drags on, the economic damage compounds.
• The Fed's Hands Are Tied, and That Hurts Stocks Most
Interest rate reductions were expected to be postponed or possibly increased in light of higher inflation caused by supply shortages.
The Dallas Fed estimates global GDP growth could fall 0.2 to 0.3 percentage points if the disruption lasts one to two quarters — and 1.3 points if it persists for three quarters. A Fed that can't cut rates into a slowdown is the worst scenario for equity valuations.
• The Damage Extends Far Beyond Oil Prices
The crisis has constrained global supplies of sulfur, fertilizer, and helium — crucial for semiconductor manufacturing — meaning supply-chain pain is spreading to tech, agriculture, and industrials. The Atlantic Council warns that a few more months of closure could ensure "a global period of stagflation" — rising prices alongside stalling growth, the worst of both worlds for stock investors.
Bottom line: VOO's 1.0% drop today is modest relative to the risk. If diplomacy stays frozen and oil stays triple-digit, the S&P 500's earnings outlook — and with it, the fund's price — faces sustained pressure with no obvious relief valve in sight.
