The Treasury Just Doubled Its Bond Buybacks — Bitcoin Traders Think They Know Why

The US Treasury announced this week it would at least double the size of its long-bond buyback operations, from $2 billion to $4 billion, targeting 10-to-20-year and 20-to-30-year Treasuries from September 9 through November 4. Bond yields fell within minutes of the announcement — the 10-year yield dropped about 5.7 basis points to 4.647%, and the 30-year fell 9 basis points to 5.196% — the same day total US public debt was confirmed to have crossed $40 trillion for the first time.

Arthur Hayes, the BitMEX co-founder, argues the move is less routine than the Treasury’s own description of it as liquidity support. His read, laid out in an interview with newsletter writer Ran Neuner, is that Washington effectively can’t let long-term borrowing costs rise much further: at $40 trillion in debt, every additional percentage point on the long end adds hundreds of billions in annual interest costs. He points out this is the second market-level intervention in three weeks, after a currency operation with Japan on August 1, and notes the Federal Reserve held rates steady at its July meeting even with short-term yields trading meaningfully above its target range — a decision he reads as the Fed declining to work against the Treasury’s own financing operation.

Whatever the underlying mechanism, something moved alongside it: bitcoin reclaimed its 200-day moving average the same week, after 270 consecutive days below it, with more than $1 billion in short positions liquidated within a few hours. Hayes draws a parallel to a similar Treasury financing shift in 2023 that preceded a broad rally across gold, equities, and bitcoin. Whether this turns out to be a sustained pattern or a single headline should become clear well before the buyback program ends November 4 — a dated, checkable test rather than a forecast. For a diversified plan, that’s the more useful thing to watch than trying to front-run which way it resolves.
