The yen strengthened more than 1% to hit 156.34 yen per dollar, its strongest level in a month, amid expectations that Japan may intervene in the market again and as investors increased bets that the Bank of Japan (BOJ) will raise interest rates at its September meeting. Data from LSEG showed the yen strengthened more than 1% against the dollar, at one point touching 156.34 yen per dollar, the strongest level since August 3, following a joint U.S.-Japan intervention to support the yen on July 31. Japan's Ministry of Finance revealed it spent a record 15.4 trillion yen, or about 98 billion dollars, to support the yen between July 30 and August 26. The United States confirmed it participated in coordinated operations to buy yen in late July, using its foreign currency holdings, though it has not officially disclosed the amount used. Some analysts believe the yen's strength may not be due to Japanese government intervention but rather to investors increasing bets that the BOJ will raise interest rates at its September 18 meeting. BOJ board member Hajime Takata said on Wednesday that the central bank should gradually raise interest rates in response to rising inflation. Meanwhile, BOJ Governor Kazuo Ueda has previously signaled that the BOJ remains open to further rate hikes. ING noted there are doubts about whether Wednesday's yen strength was actually due to intervention, as no clear anomalies were found in the foreign exchange trading system during that period. The yen's movement is also significant for the U.S. bond market, as Japanese investors are the largest foreign holders of U.S. Treasury bonds. According to U.S. Treasury data, as of June, Japanese investors held approximately 1.1 trillion dollars in U.S. Treasuries. Analysts warn that if the yen continues to weaken for an extended period, Japanese investors might reduce their holdings of U.S. Treasuries, which could add further pressure on the bond market. Chris Turner, head of global markets at ING, believes that for the yen to strengthen sustainably, it may be necessary to see clearer signals from the BOJ on monetary policy tightening, as well as new measures to encourage Japanese investors to bring funds back for domestic investment. However, expectations that the U.S. Federal Reserve (Fed) may cut interest rates in September are likely to support the dollar against the yen, making the future direction of the currency dependent on both BOJ and Fed policies.
BOJ rate hike expectations and yen strength may reduce demand for JGBs, pushing yields up.
