Coinbase Bitcoin premium index enters fifth day of negative trend

The Coinbase Bitcoin premium index has entered its fifth consecutive day of negative movement. As of September 11, 2026, the index was recorded at -0.042 percent, according to CoinGlass data.

The index measures the price difference of Bitcoin between the Coinbase and Binance exchanges. A positive index typically indicates stronger buying demand within the US market, whereas sustained negative values suggest a weakening of US-based Bitcoin demand relative to other global markets.

This recent decline follows a brief period of positive movement that began on August 24, which had ended a 97-day negative streak. Coinbase's CEO has commented on market conditions, suggesting that the market has reached a bottom and providing a timeline for a potential recovery. Investors are currently monitoring volume, volatility, and regulatory expectations to gauge the broader impact on Bitcoin and Ethereum.
