Key Takeaways:
The coordinated U.S.-Japan yen intervention of early August has faded within a month, but Japanese equities have held their gains — and the Japan Opportunities ETF is capturing that divergence.
The coordinated U.S.-Japan intervention that lifted the yen from a 40-year low in early August has largely faded, yet Japanese equities have held their ground as the currency remains roughly 20 percent undervalued against the dollar, per ING's fair-value model.
Analysts at ING said the yen is around 20 percent undervalued, a gap its fair-value model shows has persisted for years. The assessment came as Bloomberg reported that intervention gains had faded one month after the rare joint action, with fundamentals reasserting themselves.
Japan's 10-year government bond yield sits at 2.926 percent, while the U.S. 10-year trades at 4.682 percent. The dollar index stands at 99.115, near three-month lows after the Treasury's surprise move to at least double the maximum size of its long-end buyback operations to $4 billion — a step Deutsche Bank compared to "operation twist."
The divergence between a weakening yen and resilient Japanese equities matters because a stronger yen typically boosts Japanese equity valuations for foreign investors and can improve domestic consumption. If the currency firms further, the Japan Opportunities ETF could see additional upside; if intervention effects fully fade, the export-heavy Nikkei faces renewed headwinds.
The intervention, launched in early August as the yen touched a 40-year low, marked a rare joint effort by the U.S. Treasury under Secretary Scott Bessent and the Bank of Japan. The move rattled global markets, with the dollar index sliding nearly 1 percent in a single week. But within a month, Bloomberg reported, the gains had faded as fundamentals reasserted themselves.
The U.S.-Japan "currency alliance" has drawn attention from strategists, with analysts at ING questioning whether Bessent's intervention marks a turning point for the yen. The bank's fair-value model suggests the currency remains significantly undervalued, implying room for appreciation if policy conditions shift. BCA Research has similarly recommended selling the dollar against the yen, along with the South Korean won, Taiwan dollar, and Singapore dollar.
For Japanese equities, the picture is more nuanced. The Japan Opportunities ETF has drawn investor interest as currency weakness has made Japanese assets cheaper for foreign buyers in dollar terms. A stronger yen, should it materialize, would boost the local-currency value of foreign investments and could support domestic consumption — a key driver for Japan's consumer-facing companies.
The broader macro backdrop remains supportive. Japan's 10-year yield at 2.926 percent reflects the Bank of Japan's gradual normalization, while the U.S. 10-year at 4.682 percent keeps the rate differential wide. That differential has been the primary driver of yen weakness, and it is unlikely to narrow significantly until the Fed signals a more aggressive easing path.
At Jackson Hole this week, Federal Reserve Chair Kevin Warsh's debut speech is being watched closely for signals on the rate path. Citi does not expect Warsh's remarks to reverse the dollar's selling trend, according to a note cited by Investing.com. The dollar's slide to a three-month low against the euro on Treasury buyback worries has already priced in a softer U.S. rate outlook.
For the Japan Opportunities ETF, the key question is whether the yen's undervaluation eventually corrects. ING's model suggests it should, but timing remains uncertain. If the yen firms, Japanese equities could benefit from both currency translation gains and improved domestic sentiment. If it doesn't, the ETF's exposure to export-oriented companies may continue to benefit from a weaker currency.
