+## At a Glance
+
+Regulatory authority over crypto assets moved from the commodity futures regulator, Bappebti, to the financial services authority, OJK, with effect from 10 January 2025 under Government Regulation 49/2024. The reclassification is the substantive change: crypto is no longer a tradable commodity but a "digital financial asset" inside the financial services perimeter, governed by POJK 27/2024 as amended by POJK 23/2025, which closed the transition phase in January 2026. Law No. 4 of 2026, effective 17 June 2026, raises that taxonomy to primary law. The point that matters for privacy engineering is a listing criterion: POJK 27/2024 requires traded assets to be traceable and bars assets whose features conceal ownership or transaction information. Indonesia is therefore permissive toward tokenised finance and explicitly restrictive toward on-chain confidentiality. Crypto also remains prohibited as a payment instrument, because the Currency Law makes the rupiah sole legal tender.
+
+## What to Watch
+
+- A draft OJK regulation on digital financial asset offerings would establish a primary market and issuance regime.
+- How the anti-concealment listing criterion is read against privacy-preserving L2s and shielded pools, as distinct from privacy coins, remains unsettled.
+- Industry pressure to recognise stablecoins for payments runs against the Currency Law restriction.
+- Derivatives, segregated accounts, and licensing thresholds were all touched by the POJK 23/2025 amendments.

+
+## At a Glance
+
+Singapore is permissive toward digital asset activity and heavily licensed in how it permits it. Digital payment token services fall under the Payment Services Act 2019, and since 30 June 2025 a separate Digital Token Service Provider regime under the Financial Services and Markets Act 2022 has captured Singapore-incorporated firms serving customers wholly outside Singapore. That regime commenced without a transition window, and MAS indicated it would rarely license firms whose substantive activity sits entirely abroad, because it cannot supervise them. The stablecoin position is easy to overstate: MAS finalised the policy features of its single-currency stablecoin framework in August 2023, covering tokens pegged to the Singapore dollar or a G10 currency, but the implementing legislation has not yet been introduced in Parliament, so the "MAS-regulated stablecoin" label has no statutory basis yet. Tokenisation pilots run in parallel, including tokenised MAS bills settled in wholesale central bank digital currency.
+
+## What to Watch
+
+- The stablecoin bill and an expected public consultation, which determine when the single-currency framework acquires legal force.
+- Treatment of tokens that fall outside the single-currency scope, including foreign-issued and multi-currency stablecoins, which stay under the general digital payment token rules.
+- Travel rule application to transfers involving unhosted wallets.
+- Whether wholesale central bank digital currency settlement pilots produce durable market infrastructure.
