MetaPlanet's BTC reserves face a dual-edged sword challenge in exchange rates after the Bank of Japan raised interest rates. OSL Group, in collaboration with the Hong Kong Polytechnic University, released a report stating that corporate cross-border tr...

According to BBX data, yesterday's interest rate hike in Japan coincided with the Federal Reserve's decision window, creating the most intense macroeconomic shock point of the week. The latest results of institutional stablecoin research were released on the same day, with the core dynamics as follows:

• Metaplanet Inc. (TSE: 3350), as the largest corporate BTC reserve holder in Asia and the third largest publicly traded company holding Bitcoin globally (holding 40,177 BTC at an average price of about $104,000, with a target of 100,000 BTC by the end of 2026), faced a dual-edged sword pressure from the exchange rate yesterday: after the Bank of Japan announced a 25 basis point increase in the policy interest rate to 1.0%, the yen strengthened, superficially lowering the book value of BTC denominated in yen, but Bitcoin subsequently rose against the trend (CoinDesk's headline on the same day: "Bitcoin rallies after Japan rate increase"), with actual improvements in USD-denominated holdings. The company's current holdings are approximately $2.64 billion (estimated at $65,750/BTC), with the latest capital move being the issuance of 8 billion yen (about $55 million) for the 20th bond (EVO FUND) on April 24 for additional BTC purchases. Analysts warn that if the BOJ's interest rate hike triggers large-scale unwinding of "Yen Carry Trade," global risk assets including BTC may suffer systemic deleveraging shocks—however, Metaplanet holds physical BTC rather than leveraged positions, with its main risk being the exchange rate conversion effect rather than forced liquidation.

• OSL Group (Hong Kong Stock Exchange: 0863.HK) and the School of Business at the Hong Kong Polytechnic University jointly released a white paper on June 16 (The Block included it on the same day at 9:01 am EDT), titled "Cross-Border Trade Payments Will Drive the Adoption of Regulated Corporate Stablecoins." The core conclusion is that the demand for corporate-level cross-border trade payments is the main path to drive the large-scale adoption of regulated stablecoins, with importance surpassing retail consumption scenarios. OSL Group holds the Hong Kong Securities and Futures Commission licenses 7 (automated trading services) and 1 (securities trading), making it one of the few compliant exchanges globally with both institutional custody and practical experience in stablecoin settlement. Previously, it provided institutional clients with approximately $130 million in USDGO stablecoin settlement services in April 2026. This white paper provides an industrial basis for the stablecoin policy framework of Hong Kong's financial regulatory authorities, and, together with Visa's stablecoin settlement of $7 billion annualized scale, SoFi SoFiUSD's launch, and Western Union's USDPT layout, constitutes multiple points of evidence accelerating the global adoption of corporate stablecoins.
