Yen Weakness Linked to Surging Japanese Stocks, Citi Says

The Japanese yen's ongoing weakness is being fueled by the country's historically strong equity market, as investors sell the currency to hedge their stock holdings, according to new analysis from Citi.

Hedging Pressure Mounts on Yen

Analysts at the bank note that as Japanese stock indexes climb to record levels, both domestic and overseas investors are engaging in yen-selling transactions. This activity is primarily related to currency hedging and portfolio rebalancing.

When the value of Japanese equities rises, investors holding those assets often sell the yen to mitigate the risk of currency fluctuations eroding their gains. Citi states that as long as Japanese stocks continue their strong rally, this dynamic will maintain downward pressure on the yen.

Policy Options and Key Levels

According to Citi, there are two primary ways to control the yen's decline under these conditions: the Bank of Japan (BoJ) could bring forward its monetary policy normalization, or the Ministry of Finance (MoF) could intervene directly in the currency market by buying yen.

The bank has identified ¥165 per dollar as a critical level for the currency pair in the near term. The yen's weakness has been exacerbated by the BoJ's ultra-loose monetary policy, which stands in stark contrast to the tightening cycles pursued by other major central banks.

Market Outlook

Looking ahead, the pace of the stock market's ascent will be crucial. If Japanese equities continue to rise but at a slower rate, the downward pressure on the yen should ease, Citi's analysis suggests. This is because the need for investors to execute aggressive yen-sale hedges would be reduced.

Despite the near-term headwinds, Citi said its long-term bullish scenario for the yen remains largely unaffected, even if the equity rally continues.
