The G20 finance ministers and central bank governors convened in Fukuoka, Japan, on June 8–9, ahead of the main G20 summit in Osaka. Among the key topics on the agenda was the growing influence of cryptocurrencies and blockchain technology. With global financial innovation accelerating, international regulatory bodies are working closely with G20 nations to develop frameworks that ensure financial stability, consumer protection, and compliance with anti-money laundering (AML) standards.
This high-level meeting brought together representatives not only from G20 countries but also from major international organizations such as the International Monetary Fund (IMF), World Bank, Organisation for Economic Co-operation and Development (OECD), and Financial Stability Board (FSB). Their collective insights highlight both the opportunities and risks associated with digital assets.
Key Highlights from the G20 Financial Innovation Summit
Christine Lagarde, then Managing Director of the IMF, emphasized the importance of international coordination in regulating emerging financial technologies. In her speech on June 8, she stressed that managing crypto assets and non-bank financial intermediaries requires a unified approach focused on financial stability and investor protection.
“Continuing international dialogue is crucial — though it’s not as easy as it might seem,” Lagarde remarked.
Meanwhile, Adam Back, CEO of Blockstream, participated in a panel discussion on financial innovation. He highlighted how blockchain technology differs fundamentally from traditional financial infrastructure. Back advocated for the tokenization of securities and the use of blockchain in cross-border remittances. A critical point he raised was the need to issue digital versions of fiat currencies — such as a yen-pegged stablecoin — that could be securely stored in hardware wallets, reducing exposure to online threats.
Taro Aso, Japan’s Finance Minister at the time, echoed this sentiment by stating Japan’s commitment to harnessing innovations like distributed ledger technology (DLT), while simultaneously mitigating risks tied to cryptocurrencies, exchange platforms, and cybersecurity vulnerabilities.

Global Regulatory Standards for Crypto Assets
Several international regulatory bodies have been actively developing policy tools to guide national regulators. These include:
- Financial Stability Board (FSB)
- Basel Committee on Banking Supervision (BCBS)
- Committee on Payments and Market Infrastructures (CPMI)
- International Organization of Securities Commissions (IOSCO)
- Financial Action Task Force (FATF)
- OECD
These institutions are collaborating to address core concerns such as money laundering, market integrity, investor protection, and systemic risk. The FSB has taken a leading role, submitting multiple reports to the G20 outlining current regulatory approaches and identifying potential gaps.
In its report titled “Crypto-assets: Ongoing Work, Regulatory Approaches, and Potential Gaps,” the FSB reaffirmed its earlier assessment:
“To date, crypto-assets do not pose a significant threat to global financial stability. However, they raise important policy issues beyond financial stability.”
This view is shared by the European Central Bank, which concluded in a May report that crypto assets have only limited or manageable impacts on monetary policy, payment systems, and financial infrastructure in the eurozone.
Establishing a Global Cryptocurrency Exchange Registry
One of the most concrete proposals discussed was the creation of an international cryptocurrency exchange registry aimed at combating money laundering and illicit transactions.
Japan offered its national framework as a model. Under Japanese law, all cryptocurrency exchanges must register with the Financial Services Agency (FSA). As of the meeting, 19 exchanges had completed registration and were operating under strict compliance rules. Despite these measures, high-profile hacks — such as the 2018 CoinCheck breach and Zaif attack — underscored the need for tighter oversight.
Interestingly, over 140 companies expressed interest in becoming licensed exchange operators in Japan, signaling strong market demand and the need for scalable regulatory processes.

Are Cryptocurrencies a Threat to Financial Stability?
While concerns persist, leading institutions agree that current levels of crypto adoption do not jeopardize global financial systems. The FSB maintains that due to relatively small market size and limited integration with traditional finance, crypto assets remain peripheral to core banking and capital markets.
However, this could change rapidly with innovations like stablecoins and tokenized assets. Recognizing this shift, the FSB plans to release an updated report in September focusing specifically on these developments. Similarly, the OECD is evaluating how asset tokenization might affect financial markets, including its implications for liquidity, transparency, and systemic risk.
Regulatory Challenges and Jurisdictional Differences
The FSB warned that fast-moving technological advancements often outpace regulation. Without harmonized international standards, there’s a real risk of regulatory arbitrage — where firms exploit loopholes by operating in less-regulated jurisdictions.
Crypto wallets, decentralized exchanges, and peer-to-peer trading platforms fall outside traditional regulatory scopes in many countries. This fragmentation creates blind spots that could be exploited for illicit activities.
“A forward-looking regulatory approach is essential to identify gaps and prioritize oversight efforts,” the FSB noted.
To address this, G20 members are encouraged to strengthen cross-border cooperation and continuously assess whether additional coordination is needed.
How Banks Are Engaging with Crypto
The Basel Committee on Banking Supervision is actively reviewing how banks interact with crypto assets. While current Basel III capital frameworks don’t explicitly cover crypto exposures, they do set minimum requirements for other risky assets.
The committee is now considering whether to introduce specific prudential treatments for crypto-related risks — including capital buffers for banks holding or facilitating crypto transactions. This would mark a significant step toward integrating digital assets into mainstream banking supervision.
Central Bank Digital Currencies (CBDCs): Innovation vs. Caution
The CPMI conducted a comprehensive study on central bank digital currencies (CBDCs), recognizing their potential to modernize payment systems. While many central banks are exploring CBDCs, challenges remain — particularly around cost-effectiveness, cybersecurity, and legal frameworks.
There’s no consensus yet on whether CBDCs offer clear advantages over existing payment infrastructures. As such, the CPMI advises caution and recommends continued monitoring of both public and private digital tokens. Collaboration among regulators and policymakers will be key to navigating legal uncertainties.
Oversight of Crypto Investment Funds and Trading Platforms
IOSCO has made regulating crypto investment vehicles and trading platforms a top priority. By year-end, it plans to publish a final report offering guidance on managing risks related to crypto funds and exchanges.
Additionally, IOSCO launched a dedicated portal for members to share enforcement data on digital asset violations. It also established an ICO advisory network to help regulators manage initial coin offering risks across borders.
Last week, IOSCO released a consultation paper titled “Issues, Risks, and Regulatory Considerations Related to Crypto-Asset Trading Platforms,” inviting feedback from members by July 29.
