Japanese Equity Boom Fueling Yen Selling, Citi Says

The historic rally in Japanese equities is a primary driver of the yen's ongoing weakness, as investors sell the currency to hedge their stock market gains, according to an analysis by Citi. The bank argues that as long as Japanese stocks continue their strong performance, downward pressure on the yen is likely to persist.

The Hedging Connection

Citi's analysis points to both domestic and overseas investors contributing to the trend. As the value of their Japanese equity holdings climbs to record levels, these investors engage in transactions that involve selling the yen.

This activity is often related to:

• Currency Hedging: Investors sell the yen to protect their stock market profits from being eroded by adverse currency movements.
• Portfolio Rebalancing: As the value of Japanese stocks grows, investors may sell some assets (which involves selling yen) to maintain their desired portfolio allocations.

Policy and Intervention Scenarios

According to the bank, there are two primary ways to counter this equity-driven yen weakness. The first would be for the Bank of Japan to bring forward its plans for monetary policy normalization, moving away from its ultra-loose stance. The second would be direct intervention in the currency market by Japan's Ministry of Finance to buy yen.

In the near term, Citi identifies the ¥165 per dollar level as a critical threshold to watch. The divergence between the Bank of Japan's policy and the tighter stances of other major central banks, such as the U.S. Federal Reserve, has been a significant factor contributing to the yen's decline.

Market Outlook

Should the rally in Japanese stocks continue but at a slower pace, the downward pressure on the yen could ease, Citi suggests. A more moderate rate of appreciation would reduce the immediate need for investors to execute large yen-selling hedges.

Despite the current pressures, Citi states that its long-term bullish scenario for the yen remains largely unaffected by the equity market's performance. The firm's long-view anticipates other factors will eventually support a recovery for the Japanese currency.
