Recently, I've been watching the yen exchange rate and found that this yen depreciation is definitely not a short-term event. The USD/JPY is currently fluctuating between 152 and 160, and the effective exchange rate has even hit a nearly 53-year low, which is quite astonishing.

After taking a closer look at the reasons, it mainly comes down to the US-Japan interest rate differential acting up. U.S. interest rates have remained high, while the Bank of Japan's rate hike pace has been relatively slow, leading to a lot of arbitrage trading—everyone borrowing low-interest yen to invest in high-yield assets in the U.S., naturally increasing the selling pressure on the yen. Plus, Japan's government is engaging in fiscal expansion, increasing debt burdens, and market confidence in Japan's economy is also declining. Additionally, the Middle East situation is impacting the market; Japan relies heavily on imported crude oil, all of which is pushing the yen lower.

Interestingly, the Bank of Japan's April meeting still kept policy unchanged, maintaining the policy rate at 0.75%. The market initially expected a rate hike, but the Middle East conflict disrupted that rhythm. However, BOJ Governor Ueda Kazuo's comments suggest that June might become the next window for a rate increase, with the market's expectation for a June hike already rising to 76%. If a rate hike does happen, the US-Japan interest rate differential will narrow, which should be a positive for the yen.

In the short term, the yen's downward trend may continue, but the key depends on the subsequent policy measures of the Bank of Japan. If the Federal Reserve cuts rates faster than expected, causing the interest rate differential to shrink quickly, there will be room for the yen to rebound. JPMorgan is more pessimistic, predicting the yen could fall to 164 by the end of the year, but Société Générale expects it to stay around 160.

Long-term, for the yen to truly reverse its downward trend, Japan needs internal structural reforms. Economic growth momentum must significantly improve, and a healthy cycle of wages and prices needs to stabilize, so the yen's fundamentals can genuinely improve. Currently, Japan's economy still feels somewhat weak, with consumer spending not being strong enough, which is also why the BOJ remains cautious about raising rates.

For those looking to trade the yen, short-term volatility may still be endured, but logically, the yen should eventually return to a reasonable level. If you have travel needs, you can buy in installments; for investment, it depends on your risk tolerance.
