Investors are aggressively betting on a sudden turnaround in interest rates, and they’re using call options on exchange-traded funds tied to utilities stocks and long-dated Treasury bonds to do it.
Trading volume in call options tied to popular ETFs like the iShares 20+ Year Treasury Bond ETF TLT and the State Street Utilities Select Sector SPDR ETF XLU has surged recently, according to Dow Jones Market Data.

Both long-dated bonds and interest-rate-sensitive utilities stocks had come under pressure as yields on 10-year and 30-year Treasurys climbed to their highest levels in decades. The past few years have seen several examples where falling Treasury yields spurred a sudden rally in bonds and rate-sensitive stocks, a group that also includes home builders and small caps.
“If you see call-option volume expand, it usually means there’s a bullish view on the underlying product,” said Steve Sosnick, chief strategist at Interactive Brokers, in a phone interview. “If that underlying product is TLT, it’s telling you that there are bond bulls,” he said, referring to the ticker for the iShares 20+ Year Treasury Bond ETF.
Call options give investors the right, but not the obligation, to buy a certain security at a specified price by a certain date.
A jump in call-option trading volume that suggests bullishness for TLT is “very straightforward,” as it reflects traders’ expectations for long-term interest rates to come down, according to Sosnick. The stock market’s utilities sector XX:SP500.55 has traditionally benefited from lower rates.
“Utilities are typically a very rate-sensitive area,” Sosnick said — although the artificial-intelligence boom has in some cases changed what traditionally drives bullish behavior in the sector, he added.

The State Street Utilities Select Sector SPDR ETF slipped less than 0.1% on Wednesday to close almost flat, FactSet data showed. Still, shares of the ETF have dropped around 10% over the past 3 months, leaving it with a total loss so far in 2026 of 1.6% through Wednesday.
Utilities have traditionally appealed to investors because of their dividend payouts, but those payments can look less attractive compared to bonds when interest rates rise, said Sosnick.
