While investors remain focused on the prospects of Federal Reserve rate cuts and the overheated U.S. technology sector, one of this year's most resilient investment stories is unfolding in Asia. The continued weakness of the Japanese yen is acting as a powerful catalyst for the country's largest export-oriented companies, allowing Japan's stock market to maintain its leadership despite elevated global market volatility.

Despite the Bank of Japan's gradual normalization of monetary policy, the national currency remains near multi-year lows against the U.S. dollar. This has become one of the key drivers of corporate earnings growth and continues to attract international capital to Japanese equities.

Reminder:

Japan's economy has traditionally been export-driven. Automobiles, industrial machinery, electronics, robotics, and semiconductor manufacturing generate a significant share of their revenue overseas. When the yen weakens, foreign earnings automatically increase in yen terms after conversion, improving companies' financial performance even without growth in physical sales volumes.

For the stock market, this effect is especially important: analysts raise earnings forecasts, revise price targets upward, and investors gain another reason to increase their exposure to Japanese equities.

• USD/JPY continues to trade within the 161–162 range, keeping the Japanese currency near its weakest levels in almost four decades.
• During the first half of 2026, the Nikkei 225 reached a new all-time high above 73,000 points. Even after its subsequent correction, the index remains above 65,000, representing approximately 66% growth compared with the same period last year.
• The Bank of Japan has already begun its monetary tightening cycle and raised its benchmark interest rate. However, this has proven insufficient to generate a sustained recovery in the yen.
• The yield differential between the United States and Japan remains the primary source of pressure on the yen. U.S. assets continue to offer significantly higher returns, encouraging global capital to flow into dollar-denominated investments.
• Japan's trade surplus declined to approximately ¥6.9 billion in May, substantially weakening the fundamental support for the national currency.
• Yields on Japan's 10-year government bonds remain near their highest levels in almost 30 years, reflecting investors' concerns about the country's public finances and the cost of servicing its record-high government debt.

Domestic corporate reforms remain another important source of support for Japan's equity market.

• Japan's largest corporations continue expanding their share buyback programs.
• Many companies are increasing dividend payments and improving corporate governance standards.
• International investment funds are gradually increasing the allocation of Japanese equities within their global portfolios, viewing Japan as one of the most attractive alternatives to the U.S. market.

Another important growth driver remains the carry trade strategy. As long as borrowing costs in Japan remain significantly below those in the United States, investors will continue borrowing in yen and investing the proceeds in higher-yielding overseas assets. Part of those profits

subsequently flows back into Japanese equities—primarily export-oriented companies—further strengthening the relationship between a weak yen and a rising Nikkei.

What does this mean?

Over the coming weeks, GBP/JPY may become an even more informative indicator than USD/JPY. The cross remains in the 215–216 range, close to its highest levels of the past decade. At present, its movement is driven primarily by the persistent weakness of the Japanese yen rather than solely by the strength of the British economy.

As long as USD/JPY remains firmly above 160, the fundamental conditions supporting the Japanese stock market's uptrend remain intact. However, excessive yen weakness simultaneously increases the likelihood of currency intervention by both the Bank of Japan and Japan's Ministry of Finance. Any signs of such intervention could trigger a sharp appreciation of the yen, widespread profit-taking in yen crosses, and a short-term correction in Japanese equities.

For now, the weak yen remains one of the strongest pillars supporting Japan's stock market. But the longer this imbalance persists, the greater the probability that the next major market event will not be another rally in the Nikkei, but rather an attempt by Japanese authorities to halt the continued depreciation of the national currency.

So we act wisely and avoid unnecessary risks.
