Coinbase Bitcoin premium stays negative for record 90 days

The Coinbase Bitcoin Premium Index has held below zero for 90 straight days through Aug. 16, the longest negative streak on record, CoinGlass data shows.

The gauge, which tracks the price gap between Bitcoin on US-based Coinbase Pro and global exchange Binance, stood at -0.1066% as of Aug. 16, according to CoinGlass data cited by Wu Blockchain. A negative reading means Bitcoin trades at a discount on Coinbase relative to Binance, pointing to weaker buying demand from US investors or stronger selling pressure.

The current run, which began May 19, more than doubles the prior record of 40 days set between Jan. 16 and Feb. 24. The index briefly turned positive around Aug. 7-10, reaching roughly 0.08% to 0.11%, before sliding back below zero and deepening to about -0.10% by Aug. 14.

What the Discount Signals

A sustained negative premium has historically coincided with slower institutional demand and reduced spot activity from American buyers, who use Coinbase as their primary venue. The streak comes against a backdrop of mixed macro signals and intermittent outflows from US spot Bitcoin ETFs such as BlackRock's IBIT and Fidelity's FBTC, which have struggled to maintain momentum despite periodic rallies.

The divergence also highlights a split in regional demand. While US-based investors have been net sellers or less aggressive buyers, overseas participants on Binance have absorbed the relative selling, keeping Bitcoin anchored near $63,000. The discount has persisted even as the broader crypto market held steady, with Bitcoin dominance near 56 percent and ether trading in a narrow range.

Still, the gauge is not a standalone predictor. Differences in exchange liquidity, arbitrage activity and investor composition can all distort the gap, so analysts read it alongside ETF flow data rather than in isolation. Some traders treat extreme readings as contrarian signals, where a reversal in the premium could precede a price recovery.

What to Watch

Bitcoin traded near $63,000 as the streak extended, with the premium oscillating around the zero line in early August before deteriorating sharply on Aug. 13-14. Market watchers will look for a sustained turn positive in the index, or a pickup in spot ETF inflows, as signs that US buying appetite is returning. A continued discount would keep pressure on Bitcoin's near-term price action as global buyers, particularly on Binance, absorb the relative selling.
