VIX Falls as Iran Signals Conditional Hormuz Reopening

The Cboe Volatility Index fell 4.4% on Tuesday, Sept. 22, closing at 14.21 as investors weighed a possible diplomatic opening between the United States and Iran. The VIX, often called Wall Street’s fear gauge, had ended the previous session at 14.87.

The move followed reports that Iran offered to reopen the Strait of Hormuz within seven days, if Washington eases military pressure and lifts its blockade on Iranian ports. A senior Iranian official told Reuters the proposal had been sent through mediators.

The offer was conditional, not an agreement to end the conflict. Iran’s president Masoud Pezeshkian was in New York for the United Nations General Assembly, but a meeting with President Donald Trump was not planned.

Oil prices reflected the shift in expectations. Brent crude briefly fell below $98 a barrel on Tuesday, according to the Associated Press, retreating from nearly $110 last week. It remained far above the roughly $72 level before the war began.

The easing in the VIX came after a sharp rally on Monday, when the S&P 500 rose 1.5% and the Nasdaq Composite gained 2.3%, according to market data. On Tuesday, major U.S. indexes were mostly unchanged, suggesting investors were cautious about treating the diplomatic signals as a breakthrough.

The Strait matters to markets because it is a key route for oil shipments from the Persian Gulf. A lasting disruption could keep crude prices high, adding pressure to fuel costs and inflation expectations.

For now, the VIX’s decline signals lower demand for short-term protection against swings in U.S. stocks. But the gauge can turn quickly if talks stall or shipping risks rise again. Traders will watch for concrete progress on the blockade and the strait’s reopening, not just proposals.
