- Total crypto market capitalization climbed 7.01% to $2.6 trillion.
- Bitcoin advanced 8.63% over 24 hours and traded above $78,000.
- XRP and Zcash outperformed as capital moved further into altcoins.
- Treasury bond buybacks helped shift liquidity expectations across markets.
The crypto market extended a broad rally on August 21, with total capitalization reaching $2.6 trillion as Bitcoin climbed above $78,000 and gains spread across Ethereum, XRP, Solana and other large-cap assets. The move followed the U.S. Treasury’s decision to expand purchases of long-dated government debt, which initially reduced pressure in the bond market and altered investors’ expectations for financial conditions, while forced liquidations amplified the speed of the advance.
Bitcoin Leads as the Market Adds More Than 7%
Bitcoin traded at $78,040 at the time of the market snapshot, up 8.63% over 24 hours and 24.60% over seven days.
Its market capitalization stood at approximately $1.56 trillion, leaving BTC responsible for roughly 60% of the $2.6 trillion cryptocurrency market.
The rally was not confined to Bitcoin. Ethereum advanced 5.32% to $2,408.64, BNB gained 5.91% to $680.45 and Solana rose 5.15% to $92.01. Dogecoin added 9.63%, while Chainlink gained 8.44%.
The distribution of returns is notable. Bitcoin remained the principal source of market direction, but several smaller assets recorded substantially larger percentage gains as the rally matured. XRP jumped 21.55% over 24 hours to $1.39, while Zcash rose 16.94% to $653.29.

Why Treasury Buybacks Became a Crypto Catalyst
The catalyst originated outside the digital asset market.
The U.S. Treasury announced that it would double buybacks of longer-dated government securities, increasing purchases to at least $4 billion per operation. The measure followed severe pressure in the Treasury market, where long-term yields had climbed to levels not seen in years.
A Treasury buyback is not equivalent to Federal Reserve quantitative easing. The Treasury is managing the composition and liquidity of government debt rather than creating central-bank reserves to purchase securities. That distinction is important because treating the announcement as a new QE program overstates its direct monetary effect.
For crypto markets, the transmission mechanism is indirect. When long-term yields decline, even temporarily, the relative cost of holding assets without a fixed yield becomes less punitive. Lower yields can also ease broader financial conditions and weaken demand for the dollar, both of which can improve the environment for Bitcoin and other risk-sensitive assets.
Markets appear to have traded not only the size of the program but also its policy signal. CoinDesk noted that the reaction reflected expectations that authorities were willing to respond to dysfunction in long-duration government debt rather than allow tightening financial conditions to continue unchecked.
That interpretation also explains why Bitcoin was not alone. Gold and other assets responded to the Treasury announcement, while U.S. equities initially benefited as bond-market pressure eased.
The Bond Market Is Already Testing That Narrative
The strongest argument against treating the Treasury announcement as a durable liquidity shift comes from the Treasury market itself.
The initial decline in yields did not hold. The 10-year Treasury yield subsequently returned to around 4.69%, while the 30-year yield climbed back toward 5.24%, according to Associated Press market data.
That creates an unusual divergence. Bitcoin continued higher even as the bond-market reaction that helped initiate the move began to reverse.
The distinction matters for assessing whether crypto is undergoing a lasting repricing or a momentum-driven extension of the initial macro trade. Doubling Treasury buybacks can improve liquidity in specific securities, but it does not remove the underlying forces pushing yields higher, including inflation concerns, federal borrowing requirements and investor demand for greater compensation to hold long-duration debt.
Bitcoin therefore faces a more demanding test above $78,000 than it did during the first leg of the rally. Continued strength while long-term yields remain elevated would suggest crypto demand is becoming less dependent on the initial bond-market relief.
Short Liquidations Accelerated an Already Rising Market
Leverage added another layer to the move.
More than $3.1 billion in short positions had reportedly been liquidated during the earlier phase of Bitcoin’s advance, while spot Bitcoin ETFs recorded approximately $517.2 million of net inflows in a single session.
Short liquidations can accelerate a rally because traders betting on falling prices must close leveraged positions as the market moves against them. Those forced closures create additional buying demand, which can push prices through nearby resistance and trigger another layer of liquidations.
That mechanism helps explain why Bitcoin’s response became much larger than the initial macro catalyst alone might imply. Treasury policy changed the market’s interpretation of liquidity conditions, spot demand provided underlying buying pressure and leveraged positioning magnified the price response.
Current liquidation data also suggest that the most violent part of that adjustment may already have occurred. CoinMarketCap showed 24-hour liquidations at $2.25 billion, down 35.45% from the previous comparable period, even as cryptocurrency prices remained elevated.
XRP and Zcash Show Capital Moving Beyond Bitcoin
The strongest returns further down the market provide another useful signal.
XRP’s 21.55% daily gain was roughly two and a half times Bitcoin’s return, while Zcash gained 16.94%. Over seven days, XRP had risen 39.65%, Zcash 34.28%, Hyperliquid 31.48% and Chainlink 31.41%.
Ethereum presents a more nuanced picture. Its 5.32% daily advance lagged Bitcoin, but ETH was up 28.70% over seven days compared with Bitcoin’s 24.60%. Solana similarly gained 22.05% over the week despite a comparatively modest 5.15% daily move.
This pattern is different from a rally in which Bitcoin absorbs nearly all incremental demand. Once BTC establishes direction and volatility begins to normalize, traders often accept more risk elsewhere in the market. The current performance gap suggests that process has already started in selected assets rather than across every altcoin uniformly.
The distinction is important. Broad altcoin participation is stronger evidence of expanding risk appetite than isolated rallies driven by token-specific catalysts.
Greed Returns, but Positioning Is No Longer Cheap
CoinMarketCap’s Fear & Greed gauge stood at 73, placing market sentiment firmly in the “Greed” category.
That reading fits the price structure. Bitcoin has risen almost 25% over seven days, XRP nearly 40%, and several other major assets more than 30%. Traders entering after that type of move are operating under very different conditions from those buying before the breakout.
A high sentiment reading does not establish that a reversal is imminent. It does indicate that positioning has shifted quickly and that positive macro developments are increasingly reflected in current prices.
Bitcoin’s distance from its previous cycle high also provides useful perspective. Despite the sharp recovery, BTC remains well below its October 2025 record above $126,000.
The market is therefore experiencing a powerful recovery within a much larger drawdown rather than trading in price discovery.
$80,000 Becomes the First Test of Bitcoin’s Breakout
Bitcoin’s move through $75,000 removed a level that had constrained previous recovery attempts and brought the market directly toward the psychologically important $80,000 area.
Technical conditions have changed quickly. XTB noted that Bitcoin was approaching its 300-day exponential moving average for the first time since the beginning of the year as the price pushed beyond $75,000.
Holding above the former breakout area around $75,000 would preserve the stronger short-term structure and establish that level as the first meaningful support zone. Below it, the market would become more vulnerable to retracing part of the liquidation-driven advance.
On the upside, $80,000 is the immediate reference point. A move through that area would matter less because it is a round number and more because Bitcoin has previously struggled around the upper-$70,000 region during recovery attempts.
The quality of any move above $80,000 will matter as much as the breakout itself. A sustained advance accompanied by continued spot demand would carry different implications from a brief spike produced primarily by another wave of leveraged liquidations.
What Changes Next: Bond Yields Must Confirm the Crypto Move
The next test will come from the market that helped start the rally. Long-term Treasury yields have already erased much of their initial decline following the buyback announcement, leaving Bitcoin above $78,000 while the 10-year yield sits near 4.7% and the 30-year remains above 5%.
If those yields continue climbing, Bitcoin will have to absorb tighter financial conditions without the bond-market support that accompanied the initial breakout. That would provide a clearer measure of whether spot and institutional demand can sustain prices independently of the Treasury catalyst.
The macro calendar adds another test. Central bankers are gathering at Jackson Hole, with markets looking for signals on how the Federal Reserve intends to balance persistent inflation against financial-market pressures. Upcoming U.S. core PCE data will provide another reading on the inflation problem confronting policymakers.
For crypto traders, three observable variables now matter together: whether Bitcoin can retain $75,000 after the short squeeze fades, whether ETF demand remains positive and whether long-term Treasury yields stabilize. The interaction between those measures will provide more information about the durability of the rally than another isolated move through a round-number Bitcoin price.
