August 19th Market Rally: Crypto Makes a Comeback As Bessent Bails Out Bonds

By: Tanay Ved, Senior Research Associate & Cooper Duschang, Research Associate

Key Takeaways:

• Compressed volatility and a build up in derivatives positioning across crypto markets met with the Treasury’s bond market support, triggering a short squeeze that liquidated more than $1.6B on August 19th.
• BTC gained 23% to reach its highest level in three months, as the move broadened into liquid majors, fundamentally strong tokens and crypto-equities.
• The rally reversed months of underperformance against equities. BTC’s 30-day correlation to gold rose to ~0.6 going into the event, positioning it to benefit as the Treasury’s liquidity support creates a favorable backdrop for scarce assets.
• The sustainability of this rally will hinge on durable spot demand. Bitcoin ETFs added $1.7B in net inflows and exchanges saw $3.07B in BTC outflows this week, providing constructive early signals.

Macro Trigger Meets Compressed Volatility

On Wednesday, August 19th, U.S. Treasury Secretary Scott Bessent announced that the Treasury would expand its liquidity support buyback operations for longer-dated securities, from $2 billion to at least $4 billion. Long-term yields initially fell on the news, reviving the debasement trade, paired with positive sentiment from a White House meeting with crypto executives.

The market was already coiling going into this catalyst. Bitcoin spent weeks in consolidation near the low $60K range, with realized volatility compressing to its lowest levels. When the news landed, the rally triggered a short squeeze, forcing the liquidation of over $800M in short positions within a single hour, and over $1.6B across 24 hours market-wide, among the largest short liquidation events on record. BTC surged as high as $79K on the move, its best level in three months.

It was a reminder that less than a year after the October 10th flash crash, the market remains just as reflexive when a macro trigger meets crowded positioning. In this issue, we unpack the August 19th market rally, crypto’s relative performance across asset classes and assess the sustainability of the move.

The Liquidation Wave

Days before the short squeeze, open interest in BTC terms climbed to its highest level in 2026 at 220K BTC as BTC price remained range bound. This leverage accumulated during weeks of consolidation near $62K-$65K and compressed realized volatility, leaving the market sensitive to a catalyst.

Binance and Bybit saw the majority of the action, with BTC and ETH liquidations across the two venues totaling over $2.1B. The skew was consistently one-sided across majors, BTC, ETH, SOL, and ZEC all liquidated in the 90 percent or higher short range, confirming this was a broad short squeeze across assets. On Kraken, BNB liquidated just 25% short and ENA just 20%, meaning longs took the brunt of the unwind on that venue even as the rest of the market was overwhelmingly squeezing shorts.

Spot and futures activity accelerated sharply as the squeeze unfolded. Spot volume averaged $0.5B per hour on August 18, with a $1.5B hourly peak. On August 19, average hourly spot volume nearly tripled to $1.41B, while the intraday peak surged nearly 5x to $7.27B. Activity remained elevated the following day, with spot volume averaging $1.68B per hour and reaching a $3.05B peak.

Futures volume also experienced a jump. Average hourly futures volume increased from $3.57B on Tuesday to $7.77B on Wednesday, while peak hourly volume reached $42.18B. Activity remained elevated the following day averaging $6.81B per hour. Futures volume was not disproportionately more active than spot, as the futures-to-spot volume ratio was 5.51x, while the average across the three days was 5.1x.

If You’re in AI, Pivot to Crypto?

Relative Performance Across Asset Classes

In 2026 capital had been concentrated in the AI trade, with mega-cap technology and semiconductor stocks absorbing a large share of the market’s attention and liquidity. BTC and other major crypto assets had underperformed the Nasdaq 100 and AI-linked equities on a relative basis for much of the year. This week’s events brought a reversal favoring non yielding stores of value like BTC and Gold, providing a more favorable backdrop for a crypto recovery.

BTC has recently oscillated between behaving as a high-beta tech proxy and “digital gold”. Its 30-day correlation with gold had already strengthened to ~0.6 heading into this week, while its correlation with the Nasdaq 100 had faded and turned negative, positioning BTC closer to the scarce-asset side of that spectrum. Falling long-end yields appear to have supported demand for scarce assets, with BTC and gold advancing while AI-linked equities lagged.

Within crypto, the rally broadened beyond BTC as majors and higher-beta altcoins outperformed amid widespread short covering. ETH was among the largest beneficiaries of the squeeze, while HYPE extended its YTD leadership, supported by strong fundamentals and optimism around its potential U.S. market entry. Zcash (ZEC) stood out with an outsized rally as Grayscale filed to convert Zcash its trust into a spot ETF.

Pump.fun (PUMP) also outperformed alongside higher-beta DeFi tokens like Aave (AAVE) and Morpho (MORPHO), reflecting renewed risk appetite for tokens tied to specific themes and stronger underlying fundamentals. The pickup in crypto prices, volume and volatility also provides a supportive earnings backdrop for public crypto exchanges and brokerages where transaction revenues are sensitive to crypto market activity.

The ratio of crypto to RWA perpetual volume on Binance and Hyperliquid tells a similar story. The ratio compressed from ~19x in February to under 3x by August as commodity and equity perps gained share of overall activity amid geopolitical tensions and the AI rally. This week’s rally brought speculative capital back into crypto, with the ratio jumping back to 7x.

Is This Rally Sustainable?

After this week’s violent rally, BTC catapulted to ~$78K, its highest level in three months as the total crypto market cap added more than 20%. The sustainability of this macro-triggered squeeze will hinge on durable spot demand. Weekly BTC ETF inflows of $1.67B, a recovering Coinbase premium, and $3.07B in BTC exchange outflows are constructive signs of improving demand and tighter readily tradable supply.

Strategy’s switch to active balance sheet management, including selective Bitcoin sales and USD-reserve building, has reduced a key source of incremental demand. However, the market has absorbed this supply alongside rising ETF demand.

Beyond flows, BTC’s 23% rally and the jump in volatility this week rank among the largest in its history, and similarly sized moves have often preceded above-average returns in the near to medium term. Unlike a similar breakout attempt in May, which lacked comparable ETF support and faded, this week’s move carries a structural bid the prior one didn’t. With BTC approaching the psychologically important $80K level again, that combination leaves a constructive backdrop for the rally to sustain.

Futures open interest continues to build beyond pre-squeeze levels from $80B to $96B. This emphasizes renewed interest in crypto and continued appetite for exposure via derivatives. The growing open interest highlights traders rebuilding leveraged positions, a key metric to monitor when markets overheat and observe what assets traders are most exposed to.
