QCP Market Colour, 21 August 2026 1/ BTC has moved from roughly 64k to towards 76k in four sessions, but the more interesting development may be what happened in rates. The US 30-year Treasury yield reached around 5.33%, its highest since 2007, putting renewed pressure on the long end, before Treasury announced that long-end liquidity-support buybacks would increase from a maximum of $2bn to at least $4bn per operation from 9 September. Yields initially fell sharply and the dollar weakened, although Treasuries subsequently gave back much of the move.(QCP)
