What is SBI Hyper Deposit?

It is a campaign deposit from SBI Shinsei Bank, available via SBI Securities, that offers up to 5.0% equivalent before tax. Balances exceeded ¥900 billion as of January 1, and the bank says entry acceptance continues even after ¥1 trillion is reached. Check the official page for current terms and eligibility.

Is the 5.0% rate fixed for everyone?

No. The offer is described as up to 5.0% equivalent and is subject to campaign terms. The after‑tax figure is 3.9842% when the headline rate applies. Availability, amounts, and timing can vary, so review the latest conditions before applying through your SBI Securities account.

How does tax affect my return?

Interest is generally taxed, so the take‑home yield is lower than the headline figure. For example, a 5.0% equivalent gross becomes 3.9842% after tax. When comparing Japan deposit rates with funds or bonds, use after‑tax numbers to judge the real income you can spend or reinvest.

How does the KEPCO corporate bond compare to a deposit?

A deposit offers cash‑like stability and easy access, while a KEPCO corporate bond adds issuer and duration risk but provides a fixed coupon over several years. Many investors hold both: near‑term cash in deposits and medium‑term income in investment‑grade bonds for a balanced approach.
