Bitcoin jumps 8.7% after Treasury buyback plan sends yields lower

On August 19, the U.S. Treasury announced that starting September 9, it will at least double its long-end buybacks, and Bitcoin surged as much as 8.7%, reaching an intraday high of $69,749. Bitcoin’s biggest daily move since March 4 occurred not because of a cryptocurrency-related development, but due to a government announcement regarding debt management.

Bitcoin’s rally conforms to a simple macroeconomic thesis: larger Treasury buybacks put some downward pressure on long-term yields. If that downward pressure results in a significant drop in benchmark yields, it can lead to weakening of the dollar, relaxation of financial conditions, and a decline in the opportunity cost of holding Bitcoin.

The use of the word “if” is significant in this context. According to Treasury officials, this program has been designed to boost liquidity in older bonds, not deliver monetary stimulus. However, the scale of the program remains insignificant compared to the overall Treasury market.

Why a debt-plumbing notice moved crypto

Markets initially followed that chain almost step by step. Long-dated U.S. yields fell as much as 10 basis points, the 10-year yield dropped about 6 basis points to 4.66%, and the dollar index lost 0.84% to 98.80. Gold jumped 4.05%, while Bitcoin was up 6.06% at Reuters’ market snapshot before reaching its higher intraday peak reported by Decrypt.

This does not mean that the process can be termed “QE Lite” from a technical perspective. Quantitative easing (QE) is defined as the acquisition of assets by a central bank and expansion of its balance sheet, while the buying of Treasury securities is an operation in debt management. Nevertheless, the difference is of little importance for Bitcoin traders in the short run if the market reacts with lower yields and a weaker dollar.

Positioning played a hugely significant role in the move. According to CoinGlass data mentioned in Decrypt, $1.16 billion worth of crypto shorts were liquidated within one hour, of which $673.73 million worth of Bitcoin positions were liquidated. The spike occurred after the SEC proposed exemption from registration for certain crypto-asset issuers, decided on August 18, and a meeting with crypto regulators and financial regulators in the White House on August 19.

What the buybacks are actually built to fix

The objective of the Treasury Department is liquidity. In the announcement made on August 19, it raised the maximum purchase size for 10-to-20-year and 20-to-30-year nominal securities from $2 billion to at least $4 billion per operation until November 4. It attributed this decision to strong bids in the longer-dated sectors.

The research conducted by the New York Fed highlights the issue. At the time of conducting the research, there was more than $30 trillion in Treasury debt, but at the same time, on-the-run securities accounted for less than 4% of the entire sum while generating 65% of the average daily trading volume. As the securities transition to off-the-run, the trading volume declines, and transaction costs increase.

Scale remains an important factor. While buybacks can provide more liquidity and affect positioning, they cannot eliminate the factors behind rising yields. In fact, on August 18 yields rose in spite of a $2 billion expected buyback of bonds with maturities spanning from 20 to 30 years.

Yields, not headlines, still anchor the price

In its report dated August 19, Glassnode has made a similar observation with regard to Bitcoin. Prior to the rise, BTC was nearly trading at the cyclical lows hovering around $60,000 to $65,000 levels when the yield on the 10-year Treasury neared its 4.7% level. High nominal as well as real yields acted as the key macro constraint limiting Bitcoin’s behavior closer to that of a liquidity-sensitive risk asset instead of acting as an inflation hedge.

According to Glassnode, the Short-Term Holder Cost Basis stands at $68,500, lower than the True Market Mean of $75,800, a setup seen during capitulation events. The Realized Profit/Loss ratio holds at 0.75, still significantly above the levels below 0.5 that are considered seller exhaustion levels historically.

In this context, the rally initiated on Wednesday implies that Bitcoin is capable of reacting strongly to changes in yields. However, it still does not prove that the new market regime has begun.

A liquidity story that crosses borders

Arthur Hayes, the Chief Investment Officer of Maelstrom, has maintained that the breadth of Treasury debt management and availability of dollar liquidity can be more influential to Bitcoin’s performance than any specific news related to the cryptocurrency industry. In an essay published in December 2025, Hayes has even shown how Treasury buybacks lead to lower long-term yields.

“I believe Bessent will use buy backs to purchase 10-year treasuries, thus reducing the yield.” — Arthur Hayes

Hayes’ view is much more extensive compared to that of the Treasury, and hence it needs to be perceived as a macro thesis rather than a form of official government position.

The international transmission channel has less speculation. A study done by the Bank for International Settlements, which covered 184 nations, found that the global flow of Bitcoin, Ether and some major stablecoins reached the highest level of around $2.6 trillion close to the end of 2021. The main contributors to cross-border flows of native crypto-assets were global volatility, credit spreads, and funding conditions.

“Our findings highlight speculative motives and global funding conditions as key drivers of native crypto-asset flows.”
— BIS Working Paper No. 1265

Because of this, September 9th has become more important than just another date on the Treasury’s calendar. In case that larger buybacks boost liquidity at the longer end of the curve regularly enough so that Treasury yields could decrease and the dollar weaken, the jump of Bitcoin could be regarded as the first response to the easing of global financial conditions. However, if the yields go up again, the event would simply be considered a great short squeeze rather than the start of a liquidity-driven recovery.

Are bond yields more important than crypto-native news?

The Treasury market is approximately $32 trillion, while the buybacks are measured in billions. Reuters explicitly notes that the planned $83 billion of quarterly purchases represents only a small fraction of the market. Treasury’s decision to expand buybacks signaled a willingness to intervene in a stressed long-term bond market, helping drive yields lower.

If Bitcoin responds to Treasury-market interventions like a conventional liquidity-sensitive risk asset, traders may need to watch the 10-year/30-year yield spread, real yields, dollar liquidity, and Treasury auctions alongside ETF flows and crypto positioning.
