Investors Bought $327 Million of a Fund Losing 92% Per Year

When silver surged past $115 per ounce in late January, ETF inflows data shows a significant shift in positioning. ProShares UltraSHORT Silver (NYSEARCA:ZSL) saw $327 million in inflows over two weeks, a striking vote of no confidence in the precious metal’s rally. But inverse leveraged products cut both ways.

The cost of betting against silver’s bull run has been severe. ZSL is down 92% over the past year as the precious metal more than doubled. This demonstrates the fundamental risk of inverse products during sustained rallies—they amplify losses just as aggressively as they amplify gains. Even recent silver weakness hasn’t provided relief, with the ETF’s modest recovery barely offsetting the damage from the broader trend.

The Dollar and Fed Policy Matter More Than You Think

The biggest macro driver for ZSL is the U.S. dollar, which moves inversely to non-yielding assets like silver. When President Trump nominated Kevin Warsh as Federal Reserve Chairman in late January, silver crashed 35.6% in five trading days. Warsh’s hawkish reputation strengthened the dollar immediately, and ZSL spiked. Watch the dollar weekly. When the dollar strengthens on expectations of tighter monetary policy or rising real rates, silver typically weakens and ZSL benefits. Any dovish Fed pivot or dollar weakness will punish inverse positions hard. The Federal Reserve’s policy statements and economic projections, released roughly every six weeks, are essential calendar items. If real yields climb or the Fed signals slower rate cuts than markets expect, ZSL becomes more attractive as a tactical short-term trade.

Daily Resets and Volatility Decay Are Not Your Friends

ZSL’s structure creates a unique risk that matters more than any single silver price move. As a 2x leveraged inverse ETF, it resets daily to deliver twice the opposite of iShares Silver Trust (NYSEARCA:SLV | SLV Price Prediction)’s performance. Over multiple days, compounding effects erode returns in choppy markets.

Silver’s technical indicators show the extreme volatility that creates unpredictable swings for leveraged products. The RSI dropped from 82.69 on January 29 to 43.82 by February 6, signaling a dramatic momentum shift. Yet prediction markets still show strong bullish sentiment, with traders assigning high probability to further gains by month-end. This disconnect between technical weakness and sentiment creates uncertainty—if silver stabilizes rather than crashes, ZSL will bleed value through volatility decay even without a rally. Check ProShares’ daily fact sheets to monitor tracking error and AUM trends, both of which signal whether the product is functioning as intended or suffering from structural stress.

The takeaway: ZSL profits when the dollar strengthens on hawkish Fed policy, but its daily reset mechanism makes it unsuitable for anything beyond short-term tactical trades during sharp silver selloffs.
