SBI Shinsei Bank will let depositors convert up to 20% of their earned interest into Bitcoin (BTC), Ethereum (ETH), or XRP. The trial starts June 10 and ranks among Japan’s boldest crypto banking experiments yet.
The deposits stay in yen and keep their deposit insurance. Only the interest portion gains crypto exposure, and customers need a linked SBI VC Trade account to redeem the vouchers.
How Japan’s Crypto Banking Pilot Works
Based on the report, the bank converts each payout at the asset’s market price on the day interest is paid.
The base is small. Even SBI Shinsei’s headline Hyper Deposit pays about 0.42% a year, so a fifth of that interest buys only a token amount of crypto. The appeal is exposure, not returns for savers.

The design leans on SBI’s own plumbing. SBI VC Trade is the group’s licensed exchange, and its parent, SBI Holdings, is a longtime Ripple backer, which helps explain XRP’s place alongside Bitcoin and Ethereum.
The pilot also fits a wider push. SBI has been expanding its XRP strategy, testing crypto credit card rewards, and building a tokenized yen deposit network linked to JPMorgan.
Japan regulates crypto under its Payment Services Act, and the financial regulator licenses exchanges directly.
That framework lets a bank plug its affiliated exchange into ordinary deposits. SBI Shinsei plans a permanent rollout later this year if demand holds.
Why US Banks Cannot Copy the Model
The United States has moved in the opposite direction. The GENIUS Act, signed in July 2025, bars stablecoin issuers from paying any yield to holders.
Banks pressed for that line. A Treasury Borrowing Advisory Committee assessment flagged roughly $6.6 trillion in US transactional deposits as exposed if crypto products began paying a competitive yield.
A stablecoin yield loophole still lets some exchanges pass returns through, which lenders want shut.
The pending Clarity Act would shut it. A Senate Banking draft dated May 12 prohibits service providers and their affiliates from paying deposit-like yield on stablecoins, while allowing rewards tied to genuine activity.
The Clarity Act standoff remains unresolved.
Not every official shares the alarm. A White House analysis in April 2026 modeled the ban and found it would shift bank lending by only about $2 billion, far below the trillions that critics cite.
The contrast is the story. Japan folds crypto into insured deposits through a licensed exchange, while Washington writes law to keep the two apart.
Savers embracing tiny crypto payouts will shape the permanent launch. For now, Japan is testing a model US lawmakers have chosen to fence off.
