Banks
Japan's banking sector within the Nikkei 225 includes the three major banking groups—the 'megabanks'—which are among the world's largest financial institutions by total assets. These institutions operate universal banking models spanning retail banking, corporate lending, investment banking, asset management, and global financial services across dozens of countries.
The Bank of Japan's gradual policy normalization—ending negative interest rates and signaling further increases—is directly expanding net interest income. Even modest rate increases translate into substantial earnings uplifts given the megabanks' enormous deposit and loan books. Foreign investors have materially increased their allocations to Japanese banks in anticipation of this earnings recovery.

Japanese megabanks operate at extraordinary scale. For decades, the Bank of Japan's ultra-low interest rate policy compressed net interest margins and profitability—but the sector is undergoing a fundamental repricing of earnings power as Japan's long era of zero rates comes to an end, representing the most significant structural positive shift in a generation.
