In an unexpected turn of events following a dramatic downturn that resembled a "market crash," stock markets across the Asia-Pacific region rebounded violently on the morning of August 6. Key indices, including Japan's Nikkei 225 and the Topix index, saw impressive gains of over 10% during intraday tradingSimilarly, South Korea's Composite Index and KOSDAQ both surged more than 5%. This rebound came swiftly, demonstrating the volatility and unpredictability that characterize today’s global financial landscape.

On the heels of this surge, China's A-share market also displayed resilience, with the Shanghai Composite Index opening 0.63% higher, while the Shenzhen Component and the ChiNext Index both rose by over 1%. As of noon, the general trend indicated that more stocks were experiencing gains than losses, with 4,491 stocks climbing and only 700 stocks declining

Meanwhile, the Hong Kong market was not left behind, as both the Hang Seng Index and the Hang Seng Tech Index surged more than 1% at their peak.

In a stunning market reversal, Japanese and Korean stocks staged a remarkable comeback.

Following what many traders termed “Black Monday,” the early trading hours of Tuesday presented a stark contrast, filled with relief and hope as stock indices in Japan and South Korea reversed lossesAs the market opened on August 6, the Nikkei 225 index not only opened strong but saw its gains multiply to over 10%. The shift in market sentiment can largely be attributed to significant changes in the foreign exchange marketsAt the time of writing, the Japanese yen was weakening against the dollar, showing a noteworthy rise of over 1% for the USD/JPY pair, reversing from earlier lows below 142 yen per dollar to reclaim the more favorable milestone of 145 yen.

Just prior to the opening of the Japanese market, Nikkei futures had already risen by 8%, triggering a circuit breaker

Once trading started, gains rapidly expanded, leading to the suspension of trading in Japan’s growth market index futures due to market volatilityMeanwhile, futures on South Korea’s KOSDAQ also soared, activating the “SIDECAR” mechanism that pauses algorithmic trades for five minutes.

On August 5, a wave of panic swept through multiple global markets, leading to what was termed a “Black Monday” where numerous indices suffered significant declinesThis included Japan, where the Nikkei 225 and Topix indices both plummeted by over 12%, effectively wiping out the gains accumulated over the year.

Identifying the causes behind this market crash.

Market analysts have pointed to several contributing factors for the drastic drop in Japan and Korea's stock indices, alongside general instability across global markets

The expectation of interest rate cuts by the Federal Reserve and looming fears of a recession in the U.Scontributed significantly to this turmoil, casting a long shadow over investor confidenceAdditionally, speculation surrounding the depreciation of the yen and the retreat of currency arbitrage transactions may have exacerbated the situation.

Recent data from the U.SLabor Department showed that non-farm payrolls in July fell significantly short of market expectations, with the unemployment rate climbing higher than anticipatedFurthermore, the U.SCommerce Department reported a 3.3% month-over-month decline in new orders for manufactured goods in June, following a 0.5% drop in MayAlso reported, the Institute for Supply Management’s manufacturing index for July dropped to 46.8, down from 48.5 in June, drifting further from the neutral benchmark of 50. These dismal economic indicators generated investor anxiety around the possibility of an economic recession, thereby undermining confidence in market stability.

“The continuous appreciation of the yen is what truly rattled the markets,” noted Zhou Hao, chief economist at Guotai Junan International

Following a rate increase by the Bank of Japan, the yen's exchange rate against the dollar crossed significant thresholds, breaking below the 150 mark—a troubling indicator that changes in currency value may be here to stayZhou pointed out that despite rising interest rates, a significant interest rate gap remains between the yen and dollar, complicating the dynamics of the currency’s valuation.

The scenario was further elaborated by Bruce Kirk, a chief strategist for Japanese equities at Goldman Sachs, stressing that with the expectation of ongoing interest hikes from the Bank of Japan, investors remain skeptical about the resilience of the Japanese economy amid such volatilityHe stated, “Investors are doubtful that Japanese firms can sustain profits when the yen-dollar exchange rate falls below 150.” The yen depreciated to around 142 against the dollar, marking its highest level this year.

A fundamental shift looms over the Japanese stock market.

Analysts suggest that beyond the immediate fallout from “Black Monday,” Japan's stock market was already on a precarious trajectory towards essential changes

Kirk mentioned that the recent rebounds are indicative of a “turning phase.” The bullish trends observed over the past two years were fundamentally driven by a trifecta of factors: the weakness of the yen benefiting export-focused blue-chip companies, expectations of normalization in the Bank of Japan's monetary policy, and comprehensive corporate governance reforms.

“There’s no doubt that the rules of the game are changing, particularly in terms of interest rates and currency markets; this fundamental pivot is bound to be painful.” He reflected on the ongoing evolution of the “Nikkei special estimate,” suggesting that while the narrative is not entirely shattered, the principles that underpinned previous stock performances are evolving alongside current market instabilitiesInvestors, increasingly focused on domestic demand within Japan, appear to be showing renewed interest in small to medium enterprises.

Regarding the duration and severity of this recent market pullback, Kirk noted that Japanese stocks have typically experienced about seven episodes of “momentum pullbacks” within the last two years, generally resulting in a drop of approximately 7% to 8% from peak to trough, which typically requires around two months to recover

The trajectory of the current and forthcoming trends in Japan’s stock market could resemble the patterns observed following the Bank of Japan’s groundbreaking changes to yield curve control policies in December 2022.

Hideyuki Ishiguro, chief strategist at Nomura Asset Management, offered another perspective, asserting, “The panic selling could be reaching its end, prompting investors to consider stock repurchasesHowever, due to rising anxieties globally, price movements in the market today may be incredibly volatile.”

Additionally, in a research note, Ryota Sakagami of Citigroup highlighted, “We believe Japan's stock market has priced in the potential for a mild recession in the U.Sand a shift in the USD/JPY exchange rate to 140. Nonetheless, we anticipate that the transition to recovery will take time, and cautious market behavior will likely take the forefront in the meantime.”

Musk lashes out at the Federal Reserve.

In the context of U.S

markets, across the Atlantic, the major indexes suffered significant blows on August 5, with the Dow Jones Industrial Average plummeting by 1,033.99 points (2.60%) to close at 38,703.27 pointsThe NASDAQ Composite lost 576.08 points (3.43%), settling at 16,200.08, while the S&P 500 Index dropped 160.23 points (3.00%), ending at 5,186.33.

Tech giants experienced substantial declines; Apple fell 4.82%, Amazon by 4.1%, Netflix reduced by 2.46%, Google saw a 4.45% dip, Meta decreased by 2.54%, and Microsoft dropped 3.27%. Chip stocks were mostly down, leading the financial sector to also decline sharply, with energy stocks reflecting similarly bearish trends.

Reports emerged indicating that bond traders are betting on the possibility that the Federal Reserve may relax monetary policies before their next rate-setting meeting to stave off recession threats

Some traders estimate a roughly 60% likelihood that the Federal Reserve will make an emergency rate cut of 25 basis points within the week.

On August 4, Elon Musk, the CEO of Tesla, expressed his frustration on social media, stating, “The Federal Reserve needs to lower interest ratesIt is foolish that they have not done so.”

Conversely, on August 5, Mary Daly, a voting member of the Federal Reserve Open Market Committee, indicated a willingness to consider rate cuts at the upcoming September meeting, stressing the need for a balanced approach in achieving their dual mandateShe declared, “If we react to just one data point, we often end up making mistakes.” While inflation is easing, it still remains above the targeted 2%. She noted the necessity for policy rate adjustments but emphasized that timing and magnitude would hinge on forthcoming data
