How will Japan’s rate increase affect capital flow in global financial markets? - South China Morning Post

Japan's shift toward higher interest rates marks a notable change for global capital flows, since the country has spent years as a source of inexpensive funding. When Japanese rates rise, the appeal of borrowing in yen to invest in higher-yielding assets abroad can diminish. That dynamic, often linked to the yen carry trade, may influence demand for assets in markets that have benefited from Japanese investment, though the scale and speed of any shift depend on how far and how fast rates move.

For global markets, the key transmission channel is the yen itself. A stronger yen can make overseas investments less attractive for Japanese institutions, potentially encouraging capital to return home. Equity, bond, and currency markets outside Japan could feel this through changing flows, but the effect is rarely uniform and depends on relative rate differentials elsewhere.

What to watch: the pace of further rate moves, guidance from the Bank of Japan, and whether other major central banks are cutting or holding rates. The interest-rate gap between Japan and other economies will shape whether capital actually rotates, rather than simply repricing expectations.
