The Japanese yen falls, Japanese bonds rebound significantly.

On May 27,World's largest foreign exchange market the Japanese yen plummeted against the US dollar, with the USD/JPY exchange rate rising over 1% during the day, attracting widespread market attention. At the same time, Japanese long-term government bond yields fell sharply, indicating a short-term shift in market sentiment.

As of the time of reporting on May 28, the USD/JPY exchange rate had risen to 144.76, hitting a new high for the week. The yield on 20-year Japanese government bonds fell more than 15 basis points in a single day, dropping to 2.33%, with the 30-year and 40-year bond yields also declining significantly, leading to a "violent rebound" in the bond market.

Policy Signals Drive Market Volatility

The catalyst for the rapid market changes was a survey issued by the Japanese Ministry of Finance to the market. The questionnaire hinted at the possibility of reducing the issuance of long-term government bonds to address the current weak demand in the bond market. This was interpreted as an indication that the Japanese government is closely monitoring the liquidity risk in the long-term bond market and may consider intervention measures.

Previously, due to continued inflation and multiple weak bond auctions, Japanese long-term bond yields hit record highs, sparking investor concerns about the stability of the bond market. It is worth noting that bond prices and yields have an inverse relationship; rising yields typically signify falling prices and weakened demand.

Interaction Between US-Japan Interest Rate Differentials and Exchange Rates

The sharp changes in Japanese bond yields also directly affect the interest rate differential structure between the US and Japan. When Japanese long-term bond yields rise too quickly, it may prompt investors to reassess the attractiveness of US dollar assets, thereby putting pressure on the USD/JPY exchange rate. Nevertheless, the yen has appreciated by more than 8% against the US dollar so far this year, indicating a continued trend of safe-haven capital returning to Japan.

Is the Japanese Bond Crisis Resolved?

Although the market has shown a clear short-term rebound, analysts warn that structural supply and demand imbalances remain unresolved, and the fundamental risks in the Japanese bond market persist. On one hand, an aging population and declining domestic savings weaken the intrinsic buying power of long-term funds; on the other hand, persistent inflation restricts the Bank of Japan from unlimited bond purchases.

Experts note that if upcoming bond auctions can return to stability or if the Bank of Japan clarifies an increased bond-buying effort, market confidence may truly stabilize. Otherwise, the current rebound might only be a technical correction, and bond market volatility is likely to continue.
