Treasury Buybacks Spark Chain Reaction, Drive Bitcoin to $80,000

The sudden surge in Bitcoin's price to $80,000 in August was not driven by hype or speculation, but rather by a significant change in Treasury buybacks of long-dated bonds. On August 19, the US Treasury doubled its bond buyback operations, targeting the 10-30 year maturity sector. This move had a direct impact on interest rates, compressing yields and triggering a chain reaction that reached every leveraged position in digital assets.

The yield compression was significant, with the 30-year yield falling by 15 basis points from its weekly peak to August 19. This reduction in long-term yields relaxed financial conditions, easing pressures on mortgage rates, corporate borrowing costs, and the discount rate applied to all future cash flows. As a result, capital that had been retreating from risk assets began flowing back.

The Treasury's announcement was not immediately reflected in Bitcoin's price. However, within 72 hours, $3.5 billion in crypto shorts were liquidated, with Bitcoin crossing $80,000 for the first time since May. This liquidation cascade was self-reinforcing, with rising prices forcing short closures, generating more buying pressure, and pushing prices higher.

The derivatives squeeze provided the initial velocity, but sustained ETF inflows provided the follow-through. Spot Bitcoin ETFs drew $1.92 billion in net inflows for the week of August 17-21, their strongest week in nearly 10 months. The previous high came during the week of October 6-10, 2025, when $2.71 billion entered the funds.
