Bitcoin's 'Coinbase premium' achieves its longest bullish run since October's all-time high

A closely watched indicator by crypto experts, known as the Coinbase premium index, provides insight into whether US-based investors, particularly institutions, are actively purchasing Bitcoin or remaining on the sidelines. Currently, this index is signaling its most sustained bullish signal since Bitcoin traded at an all-time high above $126,000 in October. According to Coinglass data, the index has been positive for 14 days straight, from April 9 to April 22, representing the longest uninterrupted stretch of positive readings since October. The significance of this lies in the fact that Coinbase, listed on the Nasdaq, is the primary exchange for US institutions, including corporate treasuries, hedge funds, and regulated alternative investment vehicles like ETFs. When Bitcoin's price trades at a premium on Coinbase compared to offshore giant Binance, it indicates aggressive buying from US investors, a factor historically associated with bull runs. Conversely, a negative premium or discount suggests lagging US demand, with offshore markets driving the momentum. Notably, the premium was largely negative from mid-December to late February, during which time BTC declined from approximately $100,000 to nearly $60,000. The recent stretch of positive readings is particularly important, as it demonstrates sustained demand despite geopolitical uncertainty and DeFi crises. As a result, it is no surprise that Bitcoin is experiencing a rally, having surpassed $78,000 on Wednesday and achieving a month-to-date gain of 14%.
