Japan’s Asset Shift Hits Australian Bonds as JGB Yields Spike

4/23/2026

Summary

Japan Rotates Assets

Japan remains a top creditor after Germany overtook it, with ¥1,659 trillion in assets and ¥337.4 trillion in foreign debt at end-2024.
In March 2026 Japanese investors sold ¥3.76 trillion of foreign debt, bought ¥2.22 trillion of equities, and saw the 10-year JGB hit 2.49 % on April 13, its highest since 1997.
Japan, the largest foreign holder of Australian government bonds, keeps overseas-bond exposure via the GPIF and insurers, so its asset rotations can affect Australia.

Summary

Japan Hedge Costs

Hedging costs from short-term FX swaps dominate Japanese investors’ returns on foreign sovereign bonds.
Institutions hedge foreign positions with three- or six-month FX swaps that must be rolled.
The widening U.S.–Japan short-term rate gap compresses the effective yield after hedging.
Analysts say hedge costs, a narrower spread, or wider credit spreads could revive demand.
BOJ normalization makes domestic bonds attractive, raising the hurdle for bonds and prompting banks to shorten duration.

History

Historical Context

Japan's asset price bubble burst in 1991, leading to a prolonged economic stagnation known as the "Lost Decade." By 1995, public debt reached 100% of GDP, prompting the Bank of Japan to adopt aggressive monetary policies. Today, Japan's ¥1,659 trillion in assets and foreign debt reflect ongoing challenges in economic recovery, influencing global markets, including Australia.
