Asian shares showed mixed results on Monday as the yen surged against the dollar following coordinated efforts by the US and Japan. Oil prices also fell sharply.
New Delhi, India Aug 3, 2026 ALN: Asian shares were mixed Monday after the US and Japan confirmed they had acted to prop up the value of the Japanese yen against the US dollar, causing the yen to rise to its highest level since late last year. This intervention is significant in the context of Japan's ongoing struggle with currency fluctuations and the broader implications for its economy.
The yen's strengthening is a response to a series of economic pressures that have plagued Japan, including a prolonged period of low interest rates and an aggressive monetary policy aimed at stimulating growth. A weak yen has traditionally been seen as beneficial for Japanese exporters, as it makes their goods cheaper in foreign markets. However, the recent intervention underscores the delicate balance the Japanese government must maintain between supporting its export-driven economy and protecting the purchasing power of its citizens.
Oil prices fell sharply after US President Donald Trump indicated he would order US forces to refrain from attacks against Iran, claiming a deal to end the fighting in the Middle East was close. This announcement has significant implications for global oil markets, as tensions in the region have historically led to volatility in oil prices. The easing of military tensions can lead to increased supply and stabilize prices, which have been under pressure due to geopolitical uncertainties.
The dollar fell as low as 155.20 against the yen after Trump and Japanese officials confirmed they had intervened last week to curb the US currency's rise to 40-year highs against the yen. Last week, the dollar was trading near 164 yen, reflecting a dramatic shift in currency dynamics. The fluctuation of the yen against the dollar is crucial for Japan, as it affects the cost of imports and exports, influencing inflation and the overall economic landscape.
A weak yen generally helps to boost the profits of Japanese companies with substantial operations overseas, increasing their value in yen terms. This has been a key factor in Japan's export-led growth strategy, which relies heavily on competitive pricing in international markets. However, a cheap currency also weakens Japan's purchasing power overall, pushing up costs for the imports of oil and other goods needed to run its economy. This duality of effects highlights the complexities of currency management and its far-reaching implications for economic policy.
The euro rose to USD 1.1533 from USD 1.1528, reflecting a slight strengthening against the dollar. The stability of the euro is particularly important as it affects trade relations within the Eurozone and beyond, influencing economic conditions in member countries.
In share trading, Japan's Nikkei 225 index lost 1.9 per cent to 63,140.68 early Monday, while the Kospi in South Korea dropped 4.5 per cent to 6,298.75. The decline in these indices reflects investor sentiment amid ongoing market volatility and uncertainty about future economic conditions. The Kospi's dramatic rise of 17.9 per cent on Friday marked its best day in history, following significant losses earlier in the week. Such fluctuations indicate a highly reactive market, influenced by both domestic and international factors.
The Kospi is dominated by two tech giants, Samsung Electronics and SK Hynix, both of whose shares gained more than 25 per cent on Friday. However, early Monday, Samsung was trading 8 per cent lower while SK Hynix had fallen 7.8 per cent. This volatility in tech stocks can be attributed to broader market trends and investor reactions to earnings reports and forecasts, particularly in the context of the ongoing AI boom.
Hong Kong's Hang Seng index gained 0.6 per cent to 26,038.92, and the Shanghai Composite index lost 0.5 per cent to 3,812.97. The mixed performance of these indices reflects the diverse economic conditions and investor sentiment across the region, influenced by both local developments and global economic trends.
In Australia, the S&P/ASX 200 slipped 0.2 per cent to 8,961.30, indicating a cautious approach by investors in response to global market signals. Taiwan's Taiex gained 0.7 per cent, demonstrating resilience amid the broader regional trends.
The lull in fighting in the Middle East contributed to a decline in oil prices, which fell about 5 per cent. Early Monday, US benchmark crude was down 4.8 per cent at 80.58 per barrel. Brent crude, the international standard, was down 5 per cent at USD 83.87 per barrel. The decrease in oil prices can have significant implications for global inflation rates, as energy costs are a major component of overall consumer prices.
On Friday, US stocks rose to finish a wild July for Wall Street. The S&P 500 climbed 0.7 per cent, and the Dow Jones Industrial Average added 0.5 per cent. The Nasdaq composite rallied 1 per cent after briefly losing all of an early 1.3 per cent jump. These movements illustrate the volatility of the US stock market, which has been influenced by various factors, including oil price fluctuations and concerns about the profitability of major tech firms.
The US stock market has lurched up and down as oil prices shot higher due to the war with Iran and growing worries over whether Big Tech's massive investments in artificial intelligence technology will translate into profits. This uncertainty has led to significant market swings, with investors keenly watching developments in both geopolitical events and corporate earnings reports.
Friday's gains sent the S&P 500 to its first winning week in three, highlighting the market's potential for recovery amid ongoing challenges. Amazon led the market with a leap of 15.3 per cent after reporting much stronger profit for the latest quarter than analysts expected. Its profit more than tripled from a year earlier, thanks in part to an acceleration of growth in its cloud computing business. This strong performance signals the potential for growth in sectors that leverage AI and digital transformation.
Analysts noted that Amazon's results could be a signal that the company's substantial investments in AI are starting to yield positive returns, leading to increased forecasts for its spending on investments this year. The reaction was similar to what Microsoft experienced a day before, when its stock soared to its best day in nearly 18 years on signals that its AI investments may also be yielding higher profits. This trend reflects a broader optimism in the tech sector regarding the potential of AI to drive future growth.
Chip companies selling the processors and computer memory that such “hyperscalers” are scrambling to buy swung sharply again on Friday. Micron Technology, for example, went from an early jump of 6.4 per cent to a loss of 6.5 per cent before finishing with a fall of 5.9 per cent. This volatility underscores the unpredictable nature of the semiconductor market, which is heavily influenced by demand from tech giants and the cyclical nature of the industry.
However, not all tech stocks fared well; Apple dropped 7.4 per cent despite reporting stronger profit for the latest quarter than expected. Its forecast for revenue growth in the current quarter fell short of expectations, which executives attributed to a supply crunch in components being absorbed by the AI boom. This situation highlights the challenges faced by established companies in an environment where rapid technological advancements and changing consumer demands can disrupt traditional business models.
In conclusion, the mixed performance of Asian markets amid the strengthening yen and declining oil prices reflects a complex interplay of global economic factors. Investors are closely monitoring developments in the Middle East, corporate earnings, and the impact of technological advancements on market dynamics. As geopolitical tensions ease and economic conditions fluctuate, market participants will need to navigate these challenges with caution.
