Treasury’s $14 Billion Buyback Sparks $3.5 Billion Crypto Short Squeeze

Bitcoin surged approximately 25% to a two-month high exceeding $77,000 within hours of the U.S. Treasury doubling its long-dated bond buyback operations on August 19.

Falling Treasury yields triggered a short squeeze estimated at $3.5 billion across crypto derivatives.

This development raises a critical question: Did Bitcoin benefit from genuine liquidity support, or was it trading a one-day signal that the bond market partially reversed within 24 hours?

Treasury Secretary Scott Bessent’s move followed a day in which the 30-year Treasury yield hit 5.34%, its highest level since 2007. This spike occurred amid a global bond selloff driven by inflation concerns, an escalating U.S.-Israeli conflict with Iran, and growing anxiety over the U.S. fiscal trajectory. Total U.S. debt outstanding surpassed $40 trillion on the same day the buyback announcement was made.

What the Buyback Actually Buys

The Treasury will double the size of its 10- to 30-year buyback operations to at least $4 billion per operation, up from the previous $2 billion, effective from September 9 through November 4.

This adds at least $14 billion in additional liquidity support for the quarter, bringing maximum repurchases in the current window to $83 billion. This figure is measured against a $32.2 trillion Treasury market and $5.5 trillion in outstanding 20- and 30-year bonds.

The announcement achieved its intended effect initially: the 30-year yield fell to 5.184% from Tuesday’s high, and the 10-year yield dropped roughly six basis points to 4.66%.

Dan Gottlander, global head of USD and CAD swaps trading at Citi, told Reuters the move would have a significant impact on the long end of the curve, though he cautioned that the Treasury would still need to issue debt elsewhere to cover the shortfall.

“It does not change deficits, obviously, and if you are going to buy back the long end, you still will need to issue. They may issue more bills, or also in the five-year to 10-year sector.”

This distinction is crucial for those interpreting the move as quantitative easing. A Treasury buyback is financed by issuing new short-term bills to retire older, less liquid long bonds. It is a refinancing operation that swaps one liability for another without expanding the money supply, unlike the Federal Reserve’s bond purchases under QE, which create new bank reserves.

Conflating the two overstates how loose the operation actually makes financial conditions.

Why the Relief Didn’t Last

By August 20, Bessent indicated he might increase buyback sizes even further. “We’re going to increase the size of the buyback,” he said. “I would note that it could be more than the $4 billion per issue.” He argued that yields did not reflect the underlying strength of the economy, attributing the spike partly to the Iran conflict.

The bond market was not entirely convinced. The 30-year yield climbed back to 5.24% by August 20, retracing roughly half of the prior day’s drop, while the dollar recovered most of its post-announcement losses. According to Bit.com’s market analysis, Bitcoin lost the $70,000 level within hours, settling into the high-$60,000s after Fed minutes reintroduced rate-hike risk.

Thomas Simons, chief U.S. economist at Jefferies, told Reuters the surprise buyback announcement broke with the Treasury’s tradition of predictable debt issuance, describing the move as “shot from the hip.”

Evercore ISI analysts offered a more charitable view, crediting Bessent’s tactical skill in catching bond shorts off guard during thin August liquidity, but questioned whether the impact would hold given the “tidal wave” of maturing debt and deficits still to be financed.

Bitcoin Just Traded a Policy Surprise: Kalshi Lets Traders Position Before the Next One Hits.

The Treasury buyback demonstrated how quickly crypto can reprice when a macro decision catches the market off guard. Bitcoin surged, shorts were squeezed, yields fell, and then part of the move unwound as the bond market reassessed what had actually changed.

Kalshi provides traders with another way to approach such setups.

The platform offers markets around economic data, Fed policy, politics, crypto, and other real-world events that can move risk assets. Instead of waiting for Bitcoin to react to the next Treasury announcement, rate decision, or inflation print, traders can take a position on the underlying outcome itself.

This distinction matters when asset reactions are messy. Bitcoin can move due to leverage, positioning, dollar strength, and liquidity simultaneously. An event market allows traders to isolate the specific question they have conviction on.
