PayPay Bank is offering 2% interest on both dollar and yen deposits, many times the rates advertised by competing banks, as financial institutions in Japan scramble to attract funds in an environment where monetary policy is tightening and savers are starting to shop around.

The rate applies to yen deposits of up to ¥5 million, with no limit for dollar deposits. It is effective immediately, the internet-only financial institution announced Wednesday.

PayPay Bank’s standard rates are 0.1% for yen deposits and 0.05% for dollar deposits.
