Bitcoin Implied Volatility Falls to 9-Month Low as ETF Outflows Sap Short-Term Demand

Bitcoin’s implied volatility has fallen to its lowest level in nine months, underscoring weaker short-term speculative demand in the crypto market as spot exchange-traded fund outflows coincide with slowing trading activity.

Bloomberg reported on May 26 that the Bitcoin Volmex Implied Volatility Index fell to 36.11 on May 25 in Singapore. That was the lowest level since September 2025 and close to its trough since 2023.

The index measures the market’s expected Bitcoin volatility over the next 30 days based on real-time cryptocurrency options prices. Lower implied volatility in the options market suggests investors are reducing hedging against sharp near-term price swings.

Bitcoin has been trading around $77,000 after recently failing to break above $80,000. That is about 40% below its record high near $126,000 reached in October 2025. US spot Bitcoin ETFs have seen about $1 billion of net outflows this month, reversing two consecutive months of net inflows and signaling softer investor demand.

Caroline Mauron, co-founder of Orbit Markets, said Bitcoin volatility is approaching record lows. ETF outflow data also show retail interest is shifting to other trading opportunities.

The move contrasts with broader risk assets. US stocks climbed to record highs on expectations the US-Iran war may end, while South Korea’s Kospi and Taiwan’s stock market also advanced to fresh peaks on demand tied to artificial intelligence and semiconductors. Damien Loh, chief investment officer at Ericksen Capital, said negative Bitcoin ETF flows are being offset by a supportive backdrop for risk assets more broadly.

Volatility-selling strategies in the options market are also helping suppress Bitcoin volatility. Rajiv Soni, head of international portfolio management at Wave Digital Assets, said long-term holders, miners, sovereign wealth funds and large asset managers have recently made selling volatility a key strategy for generating returns on their Bitcoin holdings.

Market participants see Bitcoin’s low implied volatility as a sign it may remain rangebound for now. Speculative capital has shifted into stocks tied to artificial intelligence and memory semiconductors, draining short-term liquidity from the crypto market. Slower trading volumes have also reduced realized volatility, feeding through to lower implied volatility in options prices.
