Malaysia Bonds Face Growing Risk of Japanese Capital Exodus

Malaysia's struggling bond market may see an outflow of Japanese capital as its yield premium shrinks. According to data compiled by Bloomberg, the premium that 10-year Malaysian bonds command over equivalent Japanese notes has shrunk to around 115 basis points, down about 70% from a 2022 peak.

The Southeast Asian country's bonds have been under pressure in recent months due to increased supply and a stronger-than-expected economy that raised the odds of monetary tightening. The weakness may extend if the Bank of Japan delivers a widely anticipated interest rate hike on Friday, which would intensify worries about the departure of Japanese investors holding a record amount of Malaysia debt.

A sell-off in US government debt has deepened in recent weeks, sending the 10-year Treasury yield to its highest level in almost two decades. Meanwhile, a sharp rebound in the value of yen has upended the once-popular carry trade that involves borrowing cheaply in the Japanese currency to seek higher returns elsewhere.

Japanese investors owned 1.1 trillion yen (US$7.1 billion) worth of Malaysian debt securities as of the end of 2025, according to BOJ's latest data. This was the largest amount since the data became available in 2014 and constituted 13% of Japan's total bond investment in Asia.
