Coinbase premium hits monthly low as US institutions sell

Coinbase’s price premium fell to -0.0983% on May 21 as selling by U.S. institutional desks on Coinbase outpaced trades on Binance. The decline coincided with $1.3 billion in U.S. spot Bitcoin ETF outflows over four trading days since May 14 and roughly $1.5 billion removed from Bitcoin futures open interest this week.

The Coinbase premium measures the price gap between Coinbase, used more by U.S. institutional traders, and Binance, favored more by retail traders. A negative premium indicates Coinbase prices are lower than Binance, reflecting relative selling pressure on the U.S.-focused venue.

CryptoQuant analyst Darkfost noted that institutional selling pressure has intensified recently and that institutions trading on Coinbase Advanced have been selling more aggressively than investors on Binance. Darkfost added that uncertainty in the macro environment appears to be prompting institutions to adopt hedging strategies while they await greater clarity.

Exchange data show U.S. spot Bitcoin ETFs recorded four days of outflows totaling about $1.3 billion since May 14. At the same time, open interest-the notional value of outstanding Bitcoin futures and perpetual contracts-fell by about $1.5 billion this week, a drop market participants say removed much of the leverage that had built up during Bitcoin’s earlier rise toward $82,000. A crypto exchange commented that with short-side fuel exhausted and long positions reset lower, the next major price move will likely depend on spot demand.

LVRG research director Nick Ruck observed that the falling Coinbase premium could reflect net selling from larger holders and repositioning by institutional investors. Analyst Axel Adler described the recent flows and price action as offering “zero confirmation from US spot demand.”

Broader market data show gold has declined 5.8% over the past month, while U.S. equity benchmarks including the S&P 500 and the Dow Jones Industrial Average have risen since early April.

Bitcoin price action reflected the selling and lower derivatives exposure. Bitcoin lost about 4.5% over the past week, touched a monthly low just above $76,000 on Tuesday and was trading around $77,621 at the time of reporting, roughly 38% below its October peak. Market participants noted the pullback in futures open interest reduced leverage that had amplified Bitcoin’s earlier advance.

Long positions were pared back and ETF flows turned negative in recent days. Market participants are monitoring whether renewed spot buying from institutions or other large buyers will emerge to support market sentiment and prices.
