Since the U.S. spot Bitcoin ETF was first mentioned by the Treasury as potentially increasing long-term bond repo operations, cumulative net inflows have reached $5.3 billion. In particular, $2.4 billion came in just last week, and on Monday a single day saw $1.0 billion—making it the ninth-highest day on record.

The key is that this has turned positive from negative. In July, the year-to-date figure was still a net outflow of $5.7 billion; now the year-to-date inflow has turned positive.

The timing is worth pondering. When the Treasury proposes expanding long-term bond repos, it is essentially a liquidity-level move. The market reads it as a easing signal, so capital starts shifting into risk assets. ETFs are the compliant channel for institutional participation, and the data from this pipeline reflects real allocation intent earlier than the price does.

A ninth-place ranking for single-day inflows is not an explosive number, but moving from a net outflow of $5.7 billion to turning positive indicates that institutional sentiment has changed direction over these two months. Such changes usually don’t show up immediately in price, but they do reflect the underlying water level.
