On August 20th, Bitcoin surged past $70,000 and continued to climb, hitting a high of $72,344 during the session before retracing to around $71,500. The daily gain was approximately 11%. This marks the first time since early June that BTC has reclaimed the $70,000 level, with its market capitalization rising above $1.4 trillion.
This rally came swiftly but was not without groundwork. Since July 8th, BTC had been mostly confined within a range between $62,000 and $66,900. Six weeks of sideways trading drove volatility down to multi-year lows, leading many traders to get accustomed to shorting near the range's upper boundary. Consequently, a dense cluster of liquidation prices for short positions accumulated between $65,000 and $67,000.
Once the price broke above this zone, positions betting on a decline were forced to close. Covering these shorts requires buying BTC, which in turn pushes the price higher, ultimately creating a cascading squeeze.
The U.S. Treasury Market Ignited the Rally
The immediate catalyst came from the U.S. Treasury Department.
U.S. Treasury Secretary Scott Bessent announced that the Treasury would at least double the size of its long-term Treasury buyback operations to $4 billion. Following the news, the 30-year Treasury yield fell rapidly from its high of 5.337%, leading to a rebound in risk assets.
After BTC broke above the range's upper bound, roughly $3 billion worth of crypto short positions were liquidated within 24 hours. Approximately $1.67 billion of this came from BTC shorts and about $1.14 billion from ETH shorts; over $1 billion of these positions were liquidated within a single hour.
This explains why the price action wasn't a slow climb but rather a sharp spike in a very short period. The initial phase was fueled by improved liquidity, and the move following the breakout was driven by forced buying from short-sellers.
Subsequently, Trump urged Congress at a White House event to advance the "Clear and Comprehensive Legislation for the Integrity and Transparency of the Digital Asset Market Act" (CLARITY Act). Policy expectations added further fuel to the already ignited rally. Senate Banking Committee Chairman Tim Scott stated the bill could see progress in September, with a procedural vote tentatively scheduled for September 15th.
ETF Buying Did Not Miss Out This Time
Leverage liquidations can push prices quickly, but rallies typically struggle to sustain momentum based solely on short covering. It's worth noting this time that spot capital was also flowing in.
SoSoValue data shows that on August 19th, U.S. spot Bitcoin ETFs saw a net inflow of $517 million, the largest single-day inflow since early May. Spot Ethereum ETFs recorded a net inflow of $189 million on the same day, reaching a new high since October 2025.
A relatively positive signal also emerged in the futures market. BTC funding rates remained around 0.0101% and did not spike immediately with the price increase, suggesting spot buying drove the rally more than leveraged futures.
However, one day of significant inflows isn't enough to prove institutional capital has returned consistently. ETF data over the next two to three trading days will provide more insight into the sustainability of this breakout than a single day's figure.
With $70K Reclaimed, Risks Are Also Reaccumulating
Following the breakout, the total open interest in the crypto market increased by 9.11% to $131.25 billion. BTC open interest rose to $23.4 billion, and ETH open interest to $13.2 billion.
This means that as old shorts were cleared, new leverage has already begun entering the market. If the price continues to rise, these positions can amplify the trend; however, if BTC falls back below the breakout range, the newly added long positions could become the next candidates for liquidation.
Similarly, the U.S. Treasury market saw a reversal. After BTC touched $72,000, the 30-year Treasury yield rebounded to 5.24%, and the 10-year yield also moved back near 4.70%. The liquidity factors that aided the previous day's risk asset rally have not fully stabilized.
Market capital remains concentrated in top assets. BTC's market dominance rose to 59.2%, while the Altseason Index fell from 44 to 36. BTC's break above $70,000 does not equate to all altcoins simultaneously entering a bull cycle.
Next, the Market Will Test the Breakout's Authenticity
The $66,600 to $66,900 zone, which was previously the upper bound of the six-week trading range, now serves as a crucial area to watch for a pullback. As long as the price holds above this zone, the breakout structure remains intact. However, if ETF flows quickly reverse to net outflows and Treasury yields continue to rise, the likelihood of BTC retesting its old range increases.
The $70,000 level is certainly a conspicuous milestone, but what truly drove this rally was a simultaneous shift in spot capital flows, U.S. Treasury liquidity conditions, and short positioning. The price has already made a significant move. Those chasing the rally with leveraged buys are not just exposed to BTC's volatility but also to the risk of reduced buying pressure once the short squeeze subsides.
