Demand for stock downside protection falls to lowest level since Trump’s tariff capitulation

Wall Street’s appetite for portfolio insurance has basically evaporated. The S&P 500 single-stock put-call skew, a widely tracked measure of how much investors are willing to pay for downside protection relative to upside bets, has plunged 75% since March, landing at levels not seen in nearly two decades.

What the skew collapse actually tells us

The put-call skew measures the price gap between out-of-the-money puts (essentially crash insurance) and calls (bets on further gains). When the skew is high, investors are paying a premium for protection. When it collapses like this, it means the hedging crowd has gone quiet.

The current reading marks the lowest level of protection-buying since the period surrounding Trump’s tariff announcements, which triggered sharp drawdowns across major indexes. During the 2025 tariff episode, fear was the dominant trade. Elevated skew reflected genuine anxiety about trade policy upending corporate earnings and global supply chains. Markets sold off sharply, and the hedging surge was entirely rational. What followed was a capitulation of sorts, as the administration walked back or softened some of its most aggressive tariff postures, giving equities room to recover and eventually push to new highs.

Complacency by the numbers

A 75% decline in skew is not a subtle shift. It represents a fundamental change in how market participants are positioning themselves. Where once there was a robust market for tail-risk hedging, there’s now a collective shrug.

A near 20-year low in skew puts the current reading in rare company. The last time protection was this cheap relative to upside speculation, market conditions were very different, but the common thread is the same: investors were confident, positioned long, and not particularly worried about what could go wrong.

The macro backdrop makes this more interesting

What makes the current hedging drought notable is that it’s happening against a backdrop that isn’t exactly risk-free. Trade policy remains a live variable. Tariff frameworks established during the 2025 turbulence are still in play.

For investors sitting on unhedged long positions, the collapse in skew is worth noting for a practical reason. The cost of buying downside protection hasn’t been this low in roughly two decades.
