Coinbase traders priced $BTC at their deepest discount to the global market in 90 days on Oct 14. The Coinbase premium, the gap between the US price and the global one, closed the day at -0.142%.

That makes 40 days in a row with US buyers paying less than the rest of the world. The day's gap was also wider than the 7 day average of -0.107%.

On a separate reading, quarterly Bitcoin futures traded above spot at an annualized carry of +5.50%, the yearly rate buyers of those contracts paid over the spot price.

Since 2017, days in this very low band saw a median +0.1% BTC move over the next 7d (n=663, base +0.5%, 9y of records). History, not a forecast.
