Mizuho Financial Group (TYO:8411) is managing its securities portfolio with a highly conservative approach, strategically preparing for future investment opportunities, Bloomberg News reported Tuesday, citing CEO Masahiro Kihara.

Kihara indicated the bank will refrain from significantly expanding its bond holdings until greater clarity regarding the Bank of Japan's interest rate policy is provided, according to the report.

This prudent strategy has involved a substantial reduction in its Japanese government bond holdings over the past three years, alongside a more recent decrease in foreign bond positions after realizing some losses, added the news wire.
