Coinbase Premium Discount Narrowing but Prime Trading Drops Sharply

U.S. spot prices remain cheaper than overseas rates, though the discount has narrowed. Institutional gateway trading has also declined, making it difficult to conclude that buying pressure is recovering.

As of 1:40 p.m. on September 18, according to TokenPost PRO, Coinbase Premium was at -0.0581% after falling to -0.0893% on September 17 from -0.0182% on September 14.

A negative value indicates U.S. spot prices are lower than overseas rates. While the discount narrowed compared to the previous day, it has remained negative for five consecutive days, making it difficult to conclude that U.S. buying dominance is strong.

Coinbase Prime (Coinigy data), an institutional trading gateway, saw daily volume drop 23% from September 16's 6,974.53 BTC to 5,368.36 BTC on September 17, equivalent to approximately $360.77 million in dollar terms.

The decline suggests weaker institutional funding activity compared to the previous day.

CME Bitcoin futures leverage fund positions as of September 8 show longs at 5,146 and shorts at 13,038, with shorts being 2.5 times the longs, indicating downward pressure.

VIX, which measures U.S. stock market volatility, fell to 15.44 on September 17 from 17.71 on September 16, continuing a recent trend of declining volatility since reaching 17.84 on September 10.

A VIX below 20 is generally considered calm, and this decline is interpreted as reflecting weakened crypto demand rather than broader market fear spreading from crypto to equities.

The dollar index fell slightly to 100.21 on September 18 from 100.22 the previous day, while U.S. 10-year Treasury yields stood at 5.01% as of September 16. Although dollar pressure eased slightly, interest rates remain high.

U.S. markets appear to be leaning toward cautious observation rather than aggressive buying. The key indicators for recovery in U.S. market sentiment will be whether Coinbase Premium turns positive and whether Prime trading volume increases again.
