Japanese Bonds See ¥3.6 Trillion Weekly Swing as Foreign Investors Cut Holdings

Japanese bonds see a ¥3.6 trillion weekly flow swing as foreign investors sell ¥1.34 trillion amid rising 10-year yields.

Foreign investors sharply reduced their exposure to Japanese bonds last week, reversing a ¥2.24 trillion the previous week, according to data from Japan’s Ministry of Finance cited by Coin Bureau.

The shift amounted to a ¥3.6 trillion weekly swing in foreign flows. Foreign investors sold ¥1.34 trillion of Japanese bonds during the latest week after purchasing ¥2.24 trillion worth in the prior period.

Foreign Investors Reverse Japanese Bond Flows

The figures show a notable change in overseas demand for Japanese debt over a two-week period. After the ¥2.24 trillion inflow, foreign investors became net sellers, withdrawing ¥1.34 trillion from Japanese bonds in the following week.

At the same time, Japanese investors also reduced their exposure to overseas fixed-income assets. They sold ¥684.5 billion of foreign bonds during the same week, according to the data cited by Coin Bureau.

The contrasting flows come as Japanese bond yields have moved higher. Japan’s 10-year government bond yield is near its highest level since 1996, according to the Coin Bureau post.

Higher domestic yields can alter the relative attractiveness of Japanese debt compared with overseas bonds, although the cited data does not establish the specific reasons behind the latest weekly flows.

Japan Remains a Major Holder of US Treasuries

The developments are also relevant to US government debt markets because Japan is the largest foreign holder of US Treasuries, with about $1.2 trillion in holdings.

The latest Japanese bond-flow figures come after US Treasuries recorded their worst month in four years, according to Coin Bureau.

Changes in Japanese demand for foreign bonds are closely watched because of the scale of Japan’s overseas fixed-income holdings. However, the data cited in the post does not indicate that the latest Japanese selling of foreign bonds was specifically directed toward US Treasuries.

The figures instead show broader weekly activity involving Japanese investors and foreign bonds.

Yen Trades Near 157 per Dollar

Currency markets are another part of the backdrop. The Japanese yen was trading near 157 per US dollar at the time referenced by the Coin Bureau post.

The combination of higher Japanese government bond yields, changes in domestic and foreign bond flows, and a weak yen places Japan’s fixed-income and currency markets in focus.

The reported figures cover a single week and should therefore be distinguished from longer-term changes in foreign holdings or Japan’s overall capital flows. The next set of Ministry of Finance data will provide further information on whether the latest reversal represents a broader change in the direction of Japanese and foreign financial bond flows.
