On August 5, 2019, Bitcoin staged a dramatic surge of approximately 10%, gaining roughly $1,100 in a single session as a perfect storm of macroeconomic forces pushed Asian investors toward the leading cryptocurrency. The catalyst was China allowing the yuan to weaken past the psychologically critical 7-per-dollar threshold — a level not breached in over a decade — sending shockwaves across global currency markets and igniting what Three Arrows Capital co-founder Su Zhu described as a “macro convergence” of capital flowing out of China and into Bitcoin.
TL;DR
- The Chinese yuan broke through 7 per USD for the first time in over a decade
- Bitcoin surged ~10% (~$1,100) to trade near $11,800 as Asian exchanges dominated volume
- The U.S. Treasury officially labeled China a currency manipulator the same day
- Gold, silver, and other safe-haven assets rallied alongside Bitcoin
- Top five Bitcoin exchanges by daily volume were all Asian-based platforms
The Yuan Breaks Seven — A Decade-Old Barrier Falls
The People’s Bank of China effectively stopped defending the 7-per-dollar level on August 5, allowing the renminbi to slide past the threshold that had served as a psychological floor since the 2008 financial crisis. The move was widely interpreted as retaliation against President Donald Trump’s decision to escalate the ongoing U.S.-China trade war with new import tariffs, which had been announced just days prior.
The ripple effects were immediate and far-reaching. The Indian rupee collapsed by 1.25%, the Korean won fell 1.09%, and the Australian dollar dropped 0.7%. Major equity indices including the S&P 500 and the Dow Jones Industrial Average posted significant losses, while U.S. 10-year government bond yields declined sharply as investors fled to safety.
U.S. Treasury Designates China as Currency Manipulator
In direct response, the U.S. Treasury Department officially designated China as a currency manipulator on the evening of August 5 — a designation that carries significant diplomatic and economic weight. Treasury Secretary Steven Mnuchin issued the formal determination, marking the first time the U.S. had applied the label since 1994. President Trump took to social media to accuse China of deliberately weakening its currency, writing that the Chinese government was “manipulating the price of the renminbi.”
The designation triggered a requirement for the U.S. to engage with the International Monetary Fund to address the issue, but the immediate market reaction was one of heightened uncertainty. The escalation represented a significant deterioration in U.S.-China relations, with the trade conflict now spilling into the currency markets.
Bitcoin as a Safe Haven: The Macro Convergence Thesis
While traditional markets reeled, Bitcoin and other store-of-value assets moved sharply higher. Bitcoin’s price climbed to approximately $11,805, with its market capitalization breaching the $200 billion mark once again. Ethereum also gained 4.76% to trade at $234.22, while the broader cryptocurrency market capitalization stood near $296 billion according to CoinMarketCap data.
The volume story was particularly telling. The top five exchanges by Bitcoin trading volume were all Asian-based platforms. Bit-Z led with approximately $900 million in volume, followed by Singapore-based OEX, and then Binance with $609 million. This concentration of volume in Asian markets suggested that Chinese and regional capital was actively rotating into Bitcoin as a hedge against yuan depreciation.
Su Zhu, co-founder of Three Arrows Capital, told AMBCrypto that events like these triggered what he called “macro convergence” — a phenomenon where capital flows out of weakening fiat currencies and into Bitcoin as a “financial haven asset.” He described the situation as “fundamentally bullish” for Bitcoin and suggested that long-term accumulators might need to “hasten their buying schedule” in response to the shifting macro landscape.
Historical Parallel: The 2015-2016 Capital Flight
The events of August 5 drew immediate comparisons to the 2015-2016 Chinese market crisis, when a similar yuan devaluation triggered massive capital outflows from China. During that episode, Chinese foreign reserves tumbled by approximately $1 trillion as investors scrambled to move wealth offshore. At the time, China constricted capital outflow channels in an effort to stabilize the currency, leaving mainland investors with only a handful of overseas investment options.
This time, however, strategists noted that the PBOC appeared to be taking a different approach. Many analysts believed that once the 7-per-dollar level was breached, there was little incentive to defend the currency aggressively. Instead, Chinese authorities appeared willing to let the yuan weaken to make exports more competitive — a strategy that could further widen the U.S. trade deficit with China, which was already a major point of contention for the Trump administration.
Safe Haven Assets Rally Across the Board
Bitcoin was not alone in its ascent. Gold and silver, the traditional safe-haven assets, also posted significant gains on the day. The simultaneous rally in both cryptocurrency and precious metals markets reinforced the narrative that investors were actively seeking stores of value amid escalating geopolitical uncertainty. Federal Reserve Chairman Jerome Powell’s recent interest rate cut added another layer to the macro picture, weakening the dollar and making alternative assets more attractive.
For Bitcoin advocates, the day’s price action offered compelling evidence that the cryptocurrency was increasingly being treated as a legitimate safe-haven asset by global investors — particularly in Asia, where currency depreciation and capital controls created a natural demand for decentralized, borderless stores of value.
Why This Matters
The events of August 5, 2019 represented a watershed moment for Bitcoin’s narrative as a safe-haven asset. The yuan’s breach of the 7-per-dollar level, combined with the U.S. officially labeling China a currency manipulator, created a real-world stress test for Bitcoin’s utility as a hedge against fiat currency devaluation. The fact that Asian exchanges dominated Bitcoin volume on that day provided tangible evidence that capital was flowing from weakening fiat currencies into cryptocurrency — exactly the use case that Bitcoin’s earliest proponents had envisioned. For regulators and policymakers, the episode also underscored the growing interconnectedness of cryptocurrency markets with global macroeconomic dynamics, a relationship that would only deepen in the years to come.
