Indonesia’s banking sector has undergone a significant transformation in recent years. The framework that governs how businesses interact with banks, from accessing credit to managing accounts and conducting cross-border transactions, has grown more structured, more comprehensive, and at times, more complex. For any business operating in or entering the Indonesian market, understanding the basics of banking regulations is no longer optional. It is a practical necessity.
This guide breaks down the essentials: who the regulators are, what the key laws require, and what businesses should keep in mind when navigating Indonesia’s financial landscape.
The Two Pillars of Banking Regulation in Indonesia
Banking in Indonesia operates under a dual-authority model. The two primary regulatory bodies are Bank Indonesia (BI) and the Otoritas Jasa Keuangan, or OJK (Financial Services Authority).
Bank Indonesia functions as the country’s central bank, responsible for monetary policy, payment system oversight, and macroprudential regulation. It also regulates foreign exchange activities and money market transactions.
OJK is the independent supervisory authority that oversees the financial services sector, including all banking activities. According to Law No. 21 of 2011 on the Financial Services Authority, as amended by Law No. 4 of 2023, banking activities in Indonesia are supervised and regulated by OJK. OJK’s mandate has expanded significantly since the enactment of that amendment, commonly known as the P2SK Law.
Together, BI and OJK form the foundation of banking regulation in Indonesia. Businesses need to understand both when assessing their compliance obligations.

The P2SK Law: A Landmark Shift in the Regulatory Landscape
The most consequential development in Indonesian banking regulation in recent years is the passage of Law No. 4 of 2023 on the Development and Strengthening of the Financial Sector, commonly referred to as the P2SK Law. This omnibus law fundamentally restructured the regulatory architecture of the financial services sector.
Under the P2SK Law, OJK’s regulatory and supervisory duties were expanded beyond its previous scope to include banking, capital markets, insurance, pension funds, and financing institutions. The authority now extends to sectors including financial derivatives, carbon exchanges, technological innovation in the financial sector, digital financial assets, crypto assets, the conduct of financial services business actors, and integrated management of the financial sector.
For businesses, this is a significant development. It means that activities once considered outside the reach of banking regulation, such as certain digital transactions or fintech-facilitated financing, are now part of a unified regulatory framework under OJK’s oversight.
The P2SK Law also introduced new concepts that affect how financial instruments are structured, including the formal recognition of special purpose vehicles (SPVs) for asset securitization and the establishment of a trustee framework, both of which are supervised by OJK. These changes create new avenues for businesses seeking more sophisticated financing structures.
Key Banking Regulations Businesses Should Know
Capital Adequacy and Risk Management
In Indonesia, banks are required to hold a minimum amount of capital depending on their risk profile grade. For example, banks with a Grade 1 risk profile must maintain a minimum of 8% of their risk-weighted assets, while those with higher risk grades face progressively higher requirements.
While these capital rules apply directly to banks, they affect businesses indirectly. A bank’s capital position determines how much credit it can extend and at what terms. Understanding this dynamic helps businesses better anticipate how their banking partners assess risk and make lending decisions.
Banks are also subject to liquidity requirements under OJK Regulation No. 19 of 2024 (covering the Liquidity Coverage Ratio) and OJK Regulation No. 20 of 2024 (covering the Net Stable Funding Ratio). These rules ensure that banks maintain adequate liquid assets to meet short-term and long-term obligations, which in turn supports the reliability of banking services that businesses depend on.
Banking Regulations on Expanded Business Activities
One of the more business-relevant recent developments is OJK Regulation No. 26 of 2024 on the Expansion of Banking Business Activities (POJK 26/2024), which took effect on 13 December 2024. This regulation introduced several key provisions, including rules on capital participation activities by commercial banks, electronic signatures (e-signatures), and electronic agreements (e-agreements).
POJK 26 allows Indonesian banks to explore more opportunities for collaboration through investments with non-financial institutions. This is expected to generate more efficient and synergized financial products and services. The regulation also clarifies practices around the assignment of receivables.
For businesses, this translates into greater potential for customized financial products and easier access to banking services that were previously unavailable. Companies in sectors that were historically underserved by traditional banking may find new opportunities for financing and collaboration.
Digital Banking Regulations
To accommodate digital banking, OJK has issued guidelines allowing banks to open digital branches where customers can perform self-service banking activities. To open these branches, banks must add them to their submitted business plans to OJK, meet required capital thresholds, obtain OJK approval, and ensure the security of their electronic systems.
For businesses, this shift means banking relationships are increasingly conducted digitally. Whether it is opening accounts, accessing credit facilities, or executing transactions, companies should assess whether their internal processes and digital infrastructure are aligned with these newer delivery channels.
Governance and Compliance Obligations
Good governance is a cornerstone of Indonesia’s banking regulatory framework. OJK has issued several regulations requiring banks to implement good governance, including OJK Regulation No. 2 of 2024 on the Implementation of Governance for Sharia Commercial Banks and Sharia Business Units, and OJK Regulation No. 9 of 2024 on Good Governance Implementation for Rural Banks and Sharia Rural Banks.
While these obligations sit with the banks themselves, they shape what banks expect from the businesses they serve. Businesses applying for credit or seeking banking partnerships will find that banks now apply more rigorous due diligence, particularly around corporate governance, risk management systems, and documentation.
Anti-Money Laundering and Know Your Customer Requirements
A critical area of banking regulations that directly affects businesses is the Anti-Money Laundering (AML) and Know Your Customer (KYC) framework. Banks in Indonesia are required to verify the identity of their clients, understand the nature of their business, and monitor transactions for suspicious activity.
Businesses should be prepared to provide comprehensive documentation when opening accounts or applying for financial products. This includes corporate registration documents, proof of beneficial ownership, and in some cases, information about the nature of counterparties in transactions. The Financial Transaction Reports and Analysis Center (PPATK) oversees the reporting of suspicious financial transactions, and businesses operating in sectors with higher exposure to cross-border transactions should be particularly attentive to these requirements.
Under current regulations, mandatory AML and KYC compliance applies broadly across financial service providers, including those in the digital finance space. Entities are also required to report suspicious transactions to PPATK.
What This Means for Foreign Investors and Foreign-Owned Businesses
Businesses with foreign ownership have additional considerations under Indonesia’s banking regulations. Foreign ownership in financial service companies, including fintech entities, is subject to specific restrictions set by OJK. For commercial banks, ownership is also regulated, including rules around sole ownership, which limit any single party to being a majority shareholder in one commercial bank.
Pursuant to OJK Regulation No. 39/POJK.03/2017 on Sole Ownership in Indonesian Banking, each party may only become a sole shareholder in one commercial bank.
Foreign investors entering the Indonesian market through the acquisition of banking stakes or by establishing financial service entities should seek legal counsel to navigate ownership restrictions, licensing requirements, and mandatory regulatory filings with OJK.
Additionally, foreign businesses operating in Indonesia may have reporting and documentation obligations when transferring funds internationally. Bank Indonesia governs foreign exchange activity and imposes reporting requirements on cross-border transactions above certain thresholds.
Sharia Banking: A Parallel Regulatory Framework
Indonesia has one of the largest Islamic finance markets in the world. Sharia commercial banks and sharia business units operate under a distinct set of banking regulations, running parallel to the conventional banking framework but with their own governance, product, and compliance requirements.
OJK has issued dedicated regulations for sharia institutions, including OJK Regulation No. 2 of 2024 on governance for sharia commercial banks and OJK Regulation No. 25 of 2024 on sharia governance for sharia rural banks. Businesses that prefer or are required to operate under sharia-compliant structures should be aware that the regulatory framework is well-established and actively supervised.
Regulatory Compliance: A Practical Approach for Businesses
For most businesses, banking regulations do not require day-to-day legal oversight. However, several practical steps help ensure compliance without friction.
Understand your documentation obligations. Banks operating under OJK’s framework are required to conduct thorough customer due diligence. Having organized corporate documentation, including articles of incorporation, shareholder registers, beneficial ownership disclosures, and current business licenses, simplifies account opening and credit applications considerably.
Stay informed on regulatory changes. OJK issued 23 banking regulations in 2024 alone, comprising 18 OJK Regulations and five OJK Circular Letters. The pace of regulatory development is significant. Businesses, especially those in finance-adjacent industries or with complex banking needs, benefit from monitoring OJK’s official announcements or working with legal advisors who track these changes.
Review agreements carefully. POJK 26/2024 introduced clarity around the rules on electronic signatures and electronic agreements by commercial banks. As banking increasingly moves to digital channels, reviewing the enforceability and compliance of digital agreements is an area worth attention.
Consider sector-specific rules. Companies in fintech, digital assets, online lending, or investment management operate under sector-specific regulations that layer on top of general banking requirements. These include OJK Regulation No. 3 of 2024 on financial sector technology innovation and OJK Regulation No. 27 of 2024 on digital financial assets, including crypto assets.
How Legal Counsel Adds Value in Navigating Banking Regulations
Banking regulation in Indonesia is both detailed and dynamic. The framework includes national laws, OJK regulations, OJK circular letters, and Bank Indonesia policies, each with different scopes, timelines, and compliance requirements. For businesses dealing with cross-border financing, investment transactions, mergers and acquisitions, or entry into the Indonesian market, having experienced legal guidance is not a luxury; it is a safeguard.
A law firm with corporate and regulatory experience can assist with structuring transactions to align with regulatory requirements, conducting due diligence on financial counterparties, reviewing banking agreements, and advising on ongoing compliance obligations. This is particularly relevant for businesses navigating the implications of the P2SK Law, which reshaped the boundary between banking, fintech, and capital markets in Indonesia.
Staying Ahead of Indonesia’s Evolving Banking Framework
Indonesia’s banking sector continues to grow. Credit performance through mid-2025 has shown a positive trend, with loan growth reaching 7.77% year-on-year in June 2025. The banking sector’s capital adequacy ratio stood at 25.81%, reflecting a strong risk mitigation buffer.
This growth is supported by a regulatory framework that is actively developing, adapting to digital transformation, aligning with international standards such as Basel III, and expanding oversight into new financial domains. For businesses that understand the framework, these changes represent opportunity. For those who do not, they can become obstacles.
The most effective approach is a proactive one: stay informed, maintain strong documentation practices, and work with advisors who understand not just the letter of the regulations, but how they are applied in practice. Indonesia’s banking regulations exist to protect the integrity of the financial system, and businesses that align with that purpose are better positioned to build lasting, productive banking relationships in one of Southeast Asia’s most dynamic markets.
