Bond market volatility gauge jumps 46% while bitcoin and stocks stay calm

Bond volatility rises as bitcoin and stocks stay quiet

A measure of expected swings in U.S. Treasury yields has climbed sharply, even as bitcoin and U.S. stock markets look calm. The MOVE index jumped 46% in June and is hovering around 116, close to its March high and the highest reading since April 2025.

At the same time, bitcoin's 30-day implied volatility gauge (BVIV) and the S&P 500's VIX are near their lowest levels of the year. Implied volatility is the amount of price movement traders expect in the future.

The gap has drawn attention from macro observers, who watch stress in the bond market for signs it might spread to other assets.

Key numbers

• The MOVE index rose 46% in June and is around 116.
• That is near its March high and the loftiest reading since April 2025.
• Bitcoin's BVIV and the S&P 500's VIX are hovering near year-to-date lows.
• Cboe said investment grade and high-yield corporate bond volatility climbed from the 6th and 11th percentile lows two weeks ago to the 79th and 84th percentile highs.
• Bitcoin's daily returns do not closely track the MOVE index over 60- or 90-day windows, based on data analyzed by CoinDesk.

What the MOVE index measures

The MOVE index, officially the ICE BofA U.S. Bond Market Option Volatility Estimate, is the bond market's version of the VIX. It measures how much U.S. Treasury yields are expected to swing over the next month, using options on 2-, 5-, 10- and 30-year bonds. The 10-year bond carries the heaviest weight.

In simple terms, it shows how much movement traders are pricing into Treasury yields over the next month. It does not say whether yields will rise or fall.

Because Treasury notes are widely used as collateral in international finance and affect many borrowing costs, rising volatility in these instruments can tighten global financial conditions, push up risk premiums and trigger broad risk aversion.

A wealth manager says bond volatility leads stocks

Kurt S. Altrichter, a wealth manager and writer of the RiskSIGNAL Report, pointed to the two volatility gauges moving in different directions. He said: "The MOVE index is making higher lows while the VIX makes lower highs. The MOVE leads: it flashed turbulence before the VIX in 2022, in 2023, and at the start of the Iran war. Stocks are usually the last to get the message."

This is his assessment, not a confirmed outcome for current markets.

Cboe points to rising corporate bond volatility

Cboe said on X that corporate bond volatility has continued to climb. It said investment grade (IG) and high-yield (HY) volatility jumped from their 6th and 11th percentile lows two weeks earlier to 79th and 84th percentile highs.

The newsletter noted that the rise in MOVE is already affecting corporate borrowing.

Bitcoin has not moved with MOVE

Bitcoin's daily returns do not track the MOVE index closely over 60- or 90-day windows, according to CoinDesk's analysis. Analysts have previously told CoinDesk that sudden jumps in Treasury volatility can hurt bitcoin, and that the size of the bond move matters more than whether yields rise or fall.

According to the newsletter, a break above the March high in MOVE is the level to watch for a potential spike in bitcoin and S&P 500 volatility.

What is confirmed

• The MOVE index jumped 46% in June and is around 116.
• Bitcoin's BVIV and the S&P 500's VIX are near year-to-date lows.
• Cboe reported the percentile moves in investment grade and high-yield corporate bond volatility.
• CoinDesk's analysis found bitcoin's daily returns do not closely track MOVE over 60- or 90-day windows.

What is still unclear

It is not known whether the calm in bitcoin and stocks will last, or whether bond market volatility will spill into other markets. The claim that MOVE leads the VIX is an observer's view based on past episodes, not a confirmed forecast. Whether MOVE clears its March high is also unknown.

Why the gap matters

Treasury notes influence borrowing costs across the economy, so rising volatility there can make global finance tighter and raise risk premiums. Corporate bond volatility has already increased, according to Cboe. The newsletter also said steady ETF inflows (money going into exchange-traded funds, which are baskets of assets traded on stock exchanges), fewer large holder deposits to exchanges, and supportive regulatory tailwinds were supporting the bull case for crypto at the time of writing.
