Coinbase Bitcoin Premium Index

The Coinbase Bitcoin Premium Index measures the difference between the BTC price on Coinbase (the leading US exchange) and the global market price represented by Binance. It is a widely watched gauge of US money flows, institutional appetite and market sentiment.

Premium % = (Coinbase BTC-USD price − Binance BTCUSDT price) ÷ Binance BTCUSDT price × 100. When Coinbase trades above Binance the index is positive; when it trades below, negative.

Positive premium (>0): strong US buying — institutions and compliant capital stepping in, ample dollar liquidity, optimistic sentiment. Negative premium (<0): US selling pressure — risk appetite falling, hedging or outflows from US venues.

Coinbase is among the most regulated, institution-heavy exchanges. Persistent premium accompanied the 2020-2021 institutional bull run, while persistent discounts marked the 2022 bear market. Traders use the index to track the balance of US vs offshore demand in real time.

Why does the Coinbase premium matter?

Because Coinbase order flow skews institutional and US-regulated, a persistent premium implies genuine dollar buying rather than offshore leverage.

How often is the index updated?

Prices are sampled every 60 seconds from both exchanges' public APIs; long-range charts use daily closes backfilled to 2017-08.

Does a negative premium always mean bearish?

Not always — it can reflect temporary arbitrage dislocations or weekend liquidity. Persistent deep discounts, however, historically align with US-led selling.
