VIX Holds Above 20 for Two Weeks: What It Means for U.S. Stocks
The VIX, i.e. the volatility index of the U.S. equity market—what commentators call the “fear gauge”—has been above the 20 level since the end of February. Initially driven by uncertainty surrounding the Trump administration’s tariffs, it was then fundamentally reshaped by the outbreak of the military conflict between the United States and Iran in early March. On March 6, the day when raids on Iranian energy infrastructure intensified and the first reports of restrictions on the Strait of Hormuz emerged, the VIX reached 29.5. Since then, it has not fallen below 24.
The VIX has threshold levels that are closely monitored by investors. Below 20, the indicator suggests a low-volatility, stable environment; between 20 and 30, it signals rising tension; above 30, high volatility becomes synonymous with panic and the risk of sharp declines. Historically, the index averages around 20 points. For this reason, we examined what happens when the VIX remains above 20 for an extended period.
Data from KBMeter, updated as of March 18, 2026, clearly shows the inverse correlation between the two indicators: every time the VIX broke above 20 (highlighted in red), the SPY health score dropped into the red zone. Currently, both confirm a stressed environment—VIX at 27 and health below 50 for over a month.
From 2016 to 2026, there have been six instances in which the VIX remained above the 20 threshold for at least two consecutive weeks. We analyzed what happened to U.S. equity markets (specifically the S&P 500) during and after each of these episodes.
In five out of six cases, the S&P 500 declined throughout the duration of the episode. The average loss, measured from the first day the VIX exceeded 20 to the last day before it fell back below that threshold, was 8%. However, this aggregate figure masks an important distinction.
Short episodes—those lasting fewer than thirty trading sessions (roughly six weeks)—produced relatively contained losses, around 1–2% on average.

Historical data on the VIX and the S&P 500 covers the period from March 2016 to March 2026 and is sourced from public providers (Yahoo Finance, FRED).
