Key Highlights

● The Cboe Volatility Index fell below 17.

● The decline suggested reduced demand for market protection.

● The Fed decision removed a source of uncertainty.

● Several risks remained, including oil prices and AI earnings.

The Cboe Volatility Index, known as the VIX, fell below 17, slipping as the Federal Reserve's decision passed without a major shock. The decline suggested investors were demanding less protection against big swings in the stock market.

The VIX measures expected volatility in the S&P 500 over the next 30 days, based on options prices, and tends to rise when stocks fall sharply and investors rush to hedge.

A Fed Day Without Surprises

The Fed left its benchmark rate range unchanged in a 10-2 vote, with Governor Lisa Cook and Cleveland Fed President Beth Hammack dissenting in favor of a hike. While the dissents gave the decision a hawkish tilt, the outcome itself was widely anticipated.

Once the decision was out, one source of uncertainty was removed, which often leads to a drop in implied volatility, as options traders no longer need to price in the risk of an unexpected move.

Calm on the Surface, Risks Underneath

The low VIX reading did not mean the market was free of risk, as long-dated Treasury yields climbed sharply, and oil settled back above $100 after Yemen's Houthis claimed a missile attack on a Saudi refinery.

The VIX's calm also came before several major events, including after-the-bell earnings from Microsoft and Alphabet, which sent conflicting signals about AI spending and could test whether volatility stays subdued.
