Coinbase Premium Has Been Negative for 90 Days, but ETF Balances Grew in July

The Coinbase Premium Gap has closed negative for 90 consecutive days, from May 6 to August 3. The last positive daily close was May 5 at +$2.20. In the trailing twelve months of data this is the longest such run, more than double the previous one of 40 days in January and February. The size of the gap deserves as much attention as its sign. The August 3 reading was -$53.49, which is -0.084% on the index, and the streak averages -0.092%. Tether has been trading at $0.99912, a discount of 0.088% to the dollar, or roughly $56 per bitcoin at current spot. On the USDT-adjusted series the picture changes: 45 of the 90 days close positive, with a median of +$0.53. In July, 20 of 31 days were positive once adjusted, against zero on the raw series. If the raw gap were tracking US spot demand, fund balances should confirm it. They only partly do. Holdings across the spot bitcoin funds in CryptoQuant's fund data fell from 1,337,575 BTC on May 6 to 1,213,891 on July 31, a decline of 123,684 BTC. Almost all of that came in May and June. July added 2,277 BTC, and IBIT alone added 3,711. Through a month in which the premium never once closed positive, the funds were net buyers. This suggests the streak is being driven more by the quote currency than by absent American bids. Watching the adjusted series alongside fund balances looks like the cleaner read, with the raw gap treated as a signal mainly when the two disagree. A raw gap turning positive while Tether still trades below par would be the more meaningful shift.
