A $270 Million Seat in a Market Where Stablecoins Cannot Pay: SBI's Ajaib Investment and the Boundary Between Jurisdictions

What $270 Million Means in This Market

The size of the investment stands out sharply against Indonesian conditions. Ajaib has described the round as the country's largest technology fundraising since 2022, bringing its cumulative total since founding in 2019 to more than $500 million. Bloomberg data indicate Indonesian startups raised just $340 million in total during 2025, down from $440 million in 2024 and far below the $9.44 billion peak in 2021. A single SBI investment therefore approaches 80% of the entire country's annual startup funding. In a severely contracted funding environment, a Japanese financial group has entered the market from an unusually strong negotiating position.

Why Indonesia

Jakarta-based Ajaib offers equities, bonds, mutual funds and ETFs alongside crypto assets, stablecoins and foreign exchange. It serves millions of retail investors and provides OTC stablecoin settlement services to corporate and institutional clients. Indonesia is among ASEAN's largest retail investment markets, with more than 20 million retail investors. Crypto users numbered 14.16 million as of April 2025 according to OJK, the financial services authority, and 2024 transaction volume reached IDR 650.61 trillion — roughly four times the prior year, or approximately $40 billion. Chairman and President Yoshitaka Kitao described Ajaib, which handles both traditional financial products and digital assets, as a perfect fit for SBI's APAC Digital Economic Zone strategy.

But Stablecoins Cannot Be Used for Payment in Indonesia

This is the point that most warrants management attention. On January 10, 2025 Indonesia transferred supervision of crypto assets from the commodity futures regulator to OJK. Law No. 4 of 2026, effective June 17, 2026, then established a statutory taxonomy for digital financial assets and drew a critical line: a stablecoin may be used as a means of transaction following exchange recommendation and OJK approval, but it cannot serve as a means of payment. Bank Indonesia's currency law establishes the rupiah as the sole legal tender.

In Japan, JPYSC is an electronic payment instrument under the Payment Services Act and can be used to pay. In Indonesia, the same token is a digital financial asset that cannot. The technical properties do not change at the border; the legal ones do. What SBI and Ajaib can pursue for now is circulating JPYSC as an object of investor trading, or within institutional OTC arrangements — not as a general means of payment inside Indonesia.

Why Commit Capital Now Regardless

The answer lies in the value of taking position before the rules settle. Indonesian industry bodies continue to lobby Bank Indonesia for recognition of stablecoins as payment instruments, and that evaluation remains open as of 2026. Should approval come, whoever already holds distribution channels and a customer base at that moment gains a decisive advantage. The 20% stake is itself telling. SBI consolidated Singapore's Coinhako as a subsidiary in July 2026 but kept Ajaib at equity-method level. Consolidation would tie local regulatory risk directly to SBI's financial statements and governance; equity-method treatment preserves distance. As an entry structure into a market whose rules remain unsettled, this is a rational choice.

The Shape of SBI's Asia Strategy

SBI Group already operates SBI VC Trade in Japan, Coinhako in Singapore and crypto market maker B2C2 in the UK, overlaid with JPYSC and Strium, its finance-focused Layer 1 blockchain. Ajaib connects Southeast Asia's largest retail investor base to that network. SBI has also led an investment round in Fasset, continuing to accumulate digital asset infrastructure across the region.

1. Overseas expansion of a yen stablecoin will begin as investment-product trading, not as payment. A product designed as an electronic payment instrument under Japanese law being treated as a crypto asset or investment product in a destination market is the standard case, not the exception. Any institution planning expansion should build in, from the outset, a three-stage verification for each jurisdiction: whether the instrument can be used for payment, whether it is limited to exchange trading, and whether prior approval to handle it is required at all.
2. Ownership percentage can be designed as a regulatory risk firewall. The choice between consolidation and equity-method treatment is not merely about control. In jurisdictions where rules remain unsettled, equity-method treatment prevents local regulatory changes and supervisory engagement from flowing directly into one's own governance, while preserving the option to increase the stake and consolidate once the framework stabilizes. Institutions evaluating overseas digital asset ventures should treat ownership percentage as a regulatory variable, not only a financial one.
3. There is value in queuing for regulatory approval by holding equity. Approval for stablecoin payment use in Indonesia may or may not arrive. But if it does, what will be needed immediately — licences, customer base, distribution channels — cannot be assembled quickly. This investment is most accurately read as purchasing an option contingent on that approval. For Japanese institutions weighing Asian expansion, "capital participation as an option" is a realistic approach to markets whose prospects remain uncertain.
