Japanese Households Shift Savings to Retail Government Bonds

Japanese households are increasingly shifting savings from bank deposits into retail government bonds (JGBs) following the Bank of Japan's decision to end its long era of near-zero interest rates. Retail JGB sales nearly doubled to 6 trillion yen between April and October 2026, driven by yields exceeding 2 per cent, which significantly outperform commercial bank deposit rates that remain mostly below 1 per cent.

Satsuki Katayama, the Finance Minister, and the Ministry of Finance are exploring new retail bond products and preferential tax treatments to encourage this trend. The government aims to establish a stable domestic buyer base for government debt as the Bank of Japan reduces its own bond purchases. Lawmaker Kenji Nakanishi has advocated for this expansion to ensure long-term stability in bond ownership.

Commercial banks have expressed concern over the rapid migration of funds. Masahiko Kato, head of Mizuho Bank, warned that a sudden drain of deposits could weaken the banking sector's credit-creation function and limit its ability to supply growth capital to the broader economy.
