Japan Markets Brace for Possible Currency Intervention

The broader TOPIX index advanced 4.24 points, or 0.11%, to 3,941.57, marking its fifth consecutive daily increase, although the relatively small gain indicated a more cautious market than the Nikkei’s headline performance suggested. The Tokyo Stock Exchange’s Prime Market recorded trading volume of approximately 2.54 billion shares, with advancing stocks outnumbering decliners as buying interest remained concentrated in selected technology, retail and service companies.

Tokyo shares opened higher despite losses on Wall Street overnight, with investors buying back semiconductor-related stocks following a sharp decline in Japanese technology shares earlier in the week. The Nikkei climbed as much as 1,083 points to an intraday high of 61,902.50 at around 10:53 a.m., supported by overseas investors purchasing stock index futures and a weaker yen that improved the earnings outlook for internationally exposed Japanese companies.

At the morning close, the benchmark stood at 61,816.72, up 997.36 points, or 1.64%. However, the rally weakened substantially after trading resumed in the afternoon. By the closing bell, the index had surrendered approximately 674 points from its morning level as investors reduced positions in several high-priced technology shares ahead of the weekend.

The retreat highlighted the market’s sensitivity to movements in a relatively small group of heavily weighted companies. Semiconductor testing equipment maker Advantest was the largest contributor to the morning advance, adding approximately 370 points to the Nikkei before its contribution narrowed to about 135 points by the close. The company’s shares finished 2.08% higher, but their retreat from earlier levels accounted for roughly one-third of the index’s afternoon decline.

Fast Retailing, the operator of Uniqlo, was the largest positive contributor at the close, adding approximately 156 points to the Nikkei, while Recruit Holdings and semiconductor manufacturing equipment maker Tokyo Electron also provided support.

SoftBank Group was the biggest negative contributor, falling 5.11% and subtracting approximately 155 points from the benchmark. Medical equipment manufacturer Terumo, semiconductor materials producer Ibiden, electrical cable maker Fujikura and memory chip company Kioxia Holdings also weighed on the market.

The contrast between the major technology companies illustrated the increasingly selective nature of investor demand. While some semiconductor-related shares recovered on expectations of continuing investment in artificial intelligence infrastructure, others faced selling pressure as investors reassessed valuations and the outlook for the global technology sector.

International uncertainty intensified after Nvidia announced on November 12 that founder and Chief Executive Officer Jensen Huang had resigned, with Chief Financial Officer Colette Kress appointed interim chief executive while the company searches for a permanent successor. The leadership change unsettled investors because Nvidia occupies a central position in the global artificial intelligence industry, supplying advanced processors used in data centers and AI development.

For Japanese companies supplying semiconductor manufacturing equipment, testing systems and electronic components, developments at Nvidia carry considerable significance. The industry’s expansion has supported investment and earnings growth across Japan’s technology sector, but uncertainty over the leadership and future direction of a major customer can also increase volatility in Japanese shares.

Currency markets presented another major challenge for investors as the yen weakened beyond 160 to the dollar for the first time in more than two months, prompting a fresh warning from Finance Minister Satsuki Katayama.

The dollar had climbed above 160 yen during New York trading on November 12 and approached the threshold again in Tokyo on Friday. At around 3 p.m., it was trading near 159.97 yen, approximately 30 sen weaker than the previous afternoon, after briefly reaching about 160.02 yen during the session.

Katayama said recent currency movements had become increasingly one-sided and rapid, warning that Japanese authorities would continue cooperating closely with the U.S. Treasury and respond appropriately to developments in foreign exchange markets.

Her remarks increased attention on the possibility of renewed government intervention to support the yen, particularly after the New York Federal Reserve disclosed on November 12 details of coordinated currency intervention conducted in July.

According to the disclosure, U.S. authorities purchased approximately 79.4 billion yen against the euro on July 31 as part of an intervention effort coordinated with Japan. Japanese authorities separately purchased about 5.55 trillion yen in intervention that day, illustrating the considerable resources deployed previously to counter disorderly currency movements.

The latest decline in the yen has been driven in part by expectations that the U.S. Federal Reserve could raise interest rates further in response to persistent inflation. Higher U.S. yields have increased the appeal of dollar-denominated assets, encouraging investors to sell yen and purchase dollars.

The weaker currency has mixed consequences for Japan’s economy. Exporters and companies with substantial overseas earnings generally benefit when foreign revenues are converted into yen, but a prolonged depreciation raises the cost of imported fuel, food, raw materials and industrial components. Those pressures can increase household living expenses and squeeze profit margins for businesses unable to pass additional costs on to customers.

Japan’s government bond market also came under pressure as investors assessed the implications of stronger U.S. interest rates and persistent inflation. The yield on Japan’s benchmark 10-year government bond stood at approximately 2.854% on November 13, while the two-year yield reached 1.870% and the five-year yield stood at 2.229%. The 20-year yield was higher still at 3.726%.

Rising yields generally indicate falling bond prices and increase borrowing costs throughout the economy. For Japan, which carries a substantial government debt burden, sustained increases in long-term interest rates could raise the cost of refinancing public debt while also influencing mortgage rates, corporate borrowing and financial sector earnings.

The bond market’s movements have added another complication to the Bank of Japan’s monetary policy outlook. Policymakers must balance the need to contain inflation and currency weakness against the potential impact of higher borrowing costs on consumers, businesses and government finances. Investors are increasingly watching whether domestic price pressures and a weaker yen will strengthen the case for further monetary tightening.

Corporate earnings provided another major focus during Friday’s session, with sportswear manufacturer Asics experiencing one of the day’s sharpest share price declines despite reporting strong profit growth.

Asics announced that revenue for the January-to-September period increased 28.8% from a year earlier to 805.15 billion yen, while operating profit climbed 37.5% to 175.50 billion yen. Net profit attributable to shareholders increased 32.9% to 114.75 billion yen, supported by growth across its product categories and geographical markets.

Demand for the company’s Onitsuka Tiger brand remained strong among inbound visitors to Japan, while its sports lifestyle business recorded solid growth in North America and Europe. Improved selling prices also helped strengthen profitability.

However, Asics maintained its existing full-year forecasts, projecting revenue of 1.05 trillion yen, operating profit of 195 billion yen and net profit of 120 billion yen. The absence of an upward revision disappointed investors who had anticipated stronger guidance following the company’s rapid earnings expansion. Shares fell to their daily lower price limit of 4,180 yen, a decline of 14.34%, illustrating how even strong financial results can trigger selling when market expectations have risen ahead of an announcement.

Asahi Group Holdings, meanwhile, reported a substantial improvement in profitability for the first nine months of the year. Revenue increased 7.1% to approximately 2.31 trillion yen, while net profit jumped 55.2% to around 159.5 billion yen.

The beverage group said global sales volumes of its Asahi Super Dry brand increased 33%, while Peroni Nastro Azzurro recorded 6% growth. Higher selling prices and premium products contributed to the company’s performance, with average revenue per unit in its beer and beer-flavored beverage businesses increasing 2.1%.

However, Asahi’s results also demonstrated the importance of exchange rates in evaluating Japanese multinational companies. Although reported revenue increased 7.1%, sales declined 0.3% when currency fluctuations were excluded. Business profit rose 2.3% on a reported basis but fell 6.5% at constant exchange rates, indicating that currency movements contributed significantly to the apparent improvement.

Asahi maintained its full-year earnings forecasts, underscoring the continued importance of consumer demand, pricing strategies and international market conditions for Japan’s major food and beverage companies.

Other individual stocks experienced significant movements as investors reacted to earnings announcements and company-specific developments. Watami, V Technology, Oisix ra daichi, Akatsuki and Wacoal Holdings were among the strongest performers on the Prime Market, while Azoom, Medley, Change Holdings and Japan Elevator Service Holdings were among the largest decliners.

The market’s mixed performance extended across industries. Services, retail and warehousing-related businesses were among the stronger sectors, while nonferrous metals, machinery and precision instruments faced selling pressure. The Tokyo Stock Exchange Growth Market 250 Index also weakened, declining 1.53 points to 728.12, suggesting that investor enthusiasm had not spread evenly to smaller, growth-oriented companies.

Trading activity was also influenced by the settlement of November stock index options. The special quotation, or SQ, for Nikkei 225 options was provisionally calculated at 61,414.10, above the index’s final closing level. Such settlement events can amplify short-term trading movements as institutional investors unwind or adjust futures and options positions.

Despite Friday’s gains, the Nikkei remained below its November 5 closing level of 61,077.90 only briefly during the preceding week’s sharp correction, having plunged 3,643 points on November 6 before recovering strongly over subsequent sessions. The latest rebound therefore reflected both renewed investor demand and the continuing volatility that has characterized Tokyo trading.

Attention will now turn to Japan’s preliminary gross domestic product figures for the July-to-September quarter, scheduled for release at 8:50 a.m. on Monday, November 16. The data will provide an important indication of whether domestic consumption, business investment and exports have remained resilient despite higher prices and changing international economic conditions.

Investors will also monitor October’s U.S. producer price index, due later on Friday, along with further comments from Federal Reserve officials. Stronger-than-expected inflation data could reinforce expectations of additional U.S. interest rate increases, potentially placing renewed downward pressure on the yen and pushing Japanese government bond yields higher.

China’s industrial production and retail sales figures, scheduled for Monday, will offer further insight into economic conditions in one of Japan’s largest trading partners, with implications for manufacturers, machinery producers and companies dependent on Chinese consumer demand.

The combination of a weakening yen, rising bond yields and sharply divergent corporate earnings has created a more complicated environment for Japanese financial markets. Although the Nikkei finished Friday above 61,000, its inability to maintain the morning rally suggests investors remain cautious about the sustainability of gains in technology shares and the consequences of changing global monetary conditions.

For the week ahead, the central question will be whether improving corporate earnings and continued overseas investment can support Japanese equities while higher financing costs, persistent inflation and the possibility of currency intervention present growing risks to the broader economy.
