Points of Focus

  • Japanese depositors can now convert 20% of earned interest into BTC, ETH, or XRP while keeping deposits fully insured.
  • With deposit rates near 0.32%, the crypto option could boost returns.
  • A full rollout is planned for autumn 2026 across 4.33 million accounts.

 

SBI Shinsei Bank launched a three-month crypto rewards pilot on Wednesday, June 9, 2026, targeting deposit customers across ordinary savings accounts and time deposits ranging from three months to five years.

Depositors receive crypto exchange vouchers equivalent to 20% of their Japanese yen deposit interest payments, redeemable for Bitcoin (BTC), Ether (ETH), or XRP through SBI VC Trade, the group’s licensed crypto exchange. The program does not replace yen interest with crypto. The crypto component sits on top of normal interest, with the principal remaining fully in yen and retaining deposit insurance protection.

 

 

The macro context behind the product design is direct. The Bank of Japan (BOJ) holds its benchmark policy rate at 0.75%, with Japanese retail deposit rates sitting at approximately 0.32% as of March 2026. However, the BOJ is planning on raising interest rates to 1% during the bank’s June 15-16 policy board meeting. This will be the highest rate in 30 years.

At the current rate, a depositor holding 1 million yen earns roughly 3,200 yen annually in interest. Under the SBI Shinsei structure, that same depositor receives the full 3,200 yen in cash plus a crypto voucher worth approximately 640 yen, redeemable at live market prices on the day of conversion. The absolute sums are small, but the relative uplift against a near-zero cash yield is the product’s actual pitch.

Why a 0.75% policy rate makes crypto top-ups structurally appealing

Japan’s rate environment is central to understanding why this product exists and why it is likely to find genuine demand. The Bank of Japan held its policy rate steady at its April 2026 meeting while simultaneously cutting its growth forecast for fiscal 2026 to 0.5% and sharply raising its core inflation outlook to 2.8%, flagging that Middle East tensions and oil price pressures are crimping corporate profits and real household incomes.

The gap between a 2.8% inflation rate and a 0.32% deposit rate means Japanese savers are experiencing negative real returns on cash in real terms. This dynamic creates a structural demand pool for any product that delivers incremental yield without requiring the depositor to move money out of an insured bank account. SBI Shinsei is targeting precisely that population.

The deposits remain in insured yen accounts throughout. Only the interest portion gains crypto exposure, and customers need a linked SBI VC Trade account to redeem the vouchers. The bank converts each payout at the asset’s market price on the day interest is paid.

 

4.33 million accounts and a permanent rollout planned for autumn

The program covers approximately 4.33 million eligible deposit accounts, making it one of the largest potential retail crypto on-ramp exercises attempted through a traditional bank anywhere in the world. SBI Shinsei intends to make the service permanent if pilot demand justifies it, with the full rollout targeting autumn 2026.

The structure routes depositors directly into SBI’s own crypto ecosystem via SBI VC Trade, creating a cross-promotional channel between its banking and digital asset businesses without requiring customers to make any direct crypto purchases. The program is designed to target newcomers to digital assets rather than existing crypto investors.

 

Part of a wider SBI crypto infrastructure build

The pilot does not sit in isolation. SBI Holdings Chairman Yoshitaka Kitao revealed last month that SBI Holdings had entered preliminary discussions to acquire a stake in Bitbank, one of Japan’s largest crypto exchanges. Earlier this year, SBI partnered with Startale Group to develop a blockchain designed for tokenized stocks and introduced JPYSC, a Japanese yen-backed stablecoin.

SBI VC Trade also acquired rival exchange Bitpoint Japan in April 2026 and launched a retail USDC (USDC) lending product in March structured as a fixed-term loan to the exchange. SBI Holdings is a longtime investor in Ripple through their joint venture SBI Ripple Asia and has a history of distributing XRP as shareholder dividends, which explains XRP’s presence alongside Bitcoin and Ether in the rewards menu.

US stablecoin rules currently ban deposit-style crypto yield products, blocking American banks from offering comparable products. Japan’s regulatory framework permits what US law presently blocks, giving SBI Shinsei a structural first-mover window that no US bank currently has the legal clearance to replicate.
