Bitcoin surged above $85,000 on September 21, marking its highest level in over eight months, but a key market indicator suggests the rally may lack conviction from major U.S. buyers.
The cryptocurrency climbed about 6% over the preceding day, reaching an intraday high of $85,248 as traders liquidated more than $260 million in short positions within 60 minutes. However, Cryptoquant's Coinbase Premium Index turned negative at approximately -0.02, indicating that U.S. dollar-based buyers on Coinbase are paying less than buyers elsewhere in the market.
What the Premium Index Reveals
The Coinbase Premium Index measures the price gap between bitcoin on Coinbase, which trades against the U.S. dollar, and on Binance, which trades against the tether stablecoin. Coinbase serves as a proxy for American institutional and dollar-based purchasers, so a negative reading signals weakness in U.S. demand.
This negative reading has been the norm throughout 2024. In July, the premium spent 50 consecutive days in negative territory, the longest stretch on record at that time. While the current reading of -0.02 is less severe than the -0.07 recorded on September 15, it indicates that U.S. selling pressure has eased without converting to buying.
Leverage Rather Than Spot Demand
Analysts attribute much of the recent price climb to leveraged trading and forced short covering rather than fresh institutional capital. Traders noted that derivatives volume has been running at four to seven times spot volume, suggesting the rally is primarily driven by leverage positions and short squeezes rather than clean spot demand.
Bitcoin ETFs added just $6.21 million during the period of September 14-18, reinforcing the picture of tepid U.S. institutional interest.
Macro Conditions Remain Restrictive
The Federal Reserve raised its target interest rate range to 3.75%-4.00% on September 16, its first increase in 1,148 days. The 10-year Treasury yield also climbed above 5% during that week, creating an environment where cautious U.S. allocators typically retreat from risk assets rather than increase exposure.
For the current rally to gain traction, the Coinbase Premium Index would need to sustain positive territory, a signal that would indicate conviction from U.S. institutional buyers rather than leverage-driven moves.
