Indonesia's Financial Services Authority (OJK) and the Indonesian Institute of Accountants (IAI) have published guidance intended to standardise the accounting treatment and financial reporting of crypto assets in Indonesia, covering both crypto assets held by entities and customers’ crypto assets held in custody. The guidance is set out in Implementation Bulletin Volume 8, “Crypto Assets Owned by an Entity and Customer Crypto Assets Entrusted to an Entity”, aligned with Indonesian Financial Accounting Standards (SAK). Developed by the IAI’s Financial Accounting Standards Board with OJK involvement, it references the IFRIC Agenda Decision “Holding of Cryptocurrencies” (June 2019) and adapts it to the national crypto-asset industry context, with the stated aim of reducing interpretive divergence and improving consistency, comparability and transparency in financial reporting. OJK cited industry growth to more than 18 million users and IDR 360.3 trillion in transactions year to date through September 2025. The bulletin was launched alongside a socialisation and technical guidance event on crypto-asset accounting in Jakarta.
