The Coinbase Bitcoin Premium Index has remained in negative territory for 90 consecutive days. This is the longest ever negative streak on record of Coinbase BTC Premium Index. The Coinbase Bitcoin Premium Index tracks the difference between Bitcoin prices on Coinbase and other major exchanges. A negative reading means Bitcoin is trading at a lower price on Coinbase than on the comparison markets. This extended period of weakness highlights softer Bitcoin buying activity on Coinbase compared with other major cryptocurrency markets especially Binance.

Bitcoin Coinbase Premium Falls to -0.1066%

According to CoinGlass data, the streak began on May 19, 2026 when the index first turned red. As of August 16, the index is still negative. The latest reading stood at approximately -0.1066%, indicating that Bitcoin was trading at a relative discount on Coinbase compared with Binance.

A prolonged negative premium is often considered as a sign of weaker buying demand on Coinbase. Coinbase is widely used by US investors which means that US spot market activity is thinner. However, the index alone does not confirm sustained institutional selling or capital outflows. Other factors like differences in exchange liquidity, market structure, and trading activity also influence the premium.

The current streak has significantly surpassed the previous record. The previous was also recorded in the same year. The previous record is of 40 consecutive negative days. It was recorded between January 16 and February 24, 2026. It has also exceeded the roughly 30-day negative period recorded during the October 2025 market downturn.

Bitcoin Price Declines Alongside Prolonged Coinbase Discount

The persistent negative premium has coincided with a broader decline in Bitcoin’s price. Bitcoin traded at approximately $76,750 on May 19 when the current negative streak began. Now, the digital gold, Bitcoin, is trading around $63,000-63,100 by mid-August. This represents a decline of roughly 18% over the three-month period.

The simultaneous weakness in Bitcoin’s price and the Coinbase premium shows softer U.S. spot demand. Nevertheless, the premium should be considered alongside other macro indicators. A sustained move back toward positive territory could signal improving Coinbase demand and will likely support price as well.
