The United States Government Accountability Office (GAO) has issued a fresh warning to financial regulators, urging the Federal Deposit Insurance Corporation (FDIC) to strengthen coordination with other federal agencies as blockchain-based financial products continue to expand across the U.S. economy.

The recommendation highlights growing concerns in Washington that the rapid evolution of cryptocurrencies, stablecoins, and blockchain finance is outpacing the ability of regulators to effectively monitor systemic risks.

GAO Warns Regulators Are Not Coordinating Enough

In a letter addressed to FDIC Chairman Travis Hill and publicly released this week, the GAO reiterated concerns first raised in 2024 regarding the lack of a formal, ongoing framework for monitoring blockchain-related financial risks.

According to the watchdog agency, while digital asset adoption has accelerated dramatically, federal regulators still lack a permanent coordination mechanism to collectively identify threats and develop timely responses.

“Blockchain-related financial products and services have grown substantially, yet regulators continue to lack an ongoing coordination mechanism for addressing blockchain risks,” the GAO stated.

The agency warned that fragmented oversight could leave financial institutions vulnerable as digital assets become increasingly integrated into traditional banking systems.

Blockchain Remains on GAO’s High-Risk List

The GAO has continued to classify blockchain technology and crypto-related financial activities as a High-Risk Area, a designation reserved for sectors where management challenges or inadequate oversight could expose the U.S. financial system to significant vulnerabilities.

The agency noted that regulators have struggled to keep pace with innovations including:

• Stablecoins
• Blockchain-based payment systems
• Tokenized financial assets
• Decentralized finance (DeFi)
• Digital asset custody services
• Cross-border crypto settlements

As these technologies become more mainstream, the need for coordinated supervision has become increasingly urgent.

FDIC’s Expanding Role in Crypto Regulation

The warning comes at a crucial time for the FDIC.

Following the passage of the GENIUS Act, the FDIC now serves as the primary regulator for stablecoin issuers that operate as subsidiaries of federally supervised banks.

Meanwhile, lawmakers in the U.S. Senate continue to debate broader cryptocurrency legislation that could significantly expand the responsibilities of banking regulators across the digital asset industry.

The GAO believes this expanding role makes inter-agency cooperation even more important.

“Establishing a formal coordination mechanism would help regulators collectively identify risks and develop effective regulatory responses in a timely manner.”

Calls for Stronger Supervision of Banks

Beyond blockchain oversight, the GAO also recommended reforms to the FDIC’s internal supervisory practices.

The agency urged the FDIC to introduce mandatory rotation of case managers and bank supervisors.

According to the report, allowing regulators to oversee the same financial institutions for extended periods may compromise their independence and weaken the effectiveness of supervision.

The watchdog argued that regular rotation would:

• Strengthen regulatory independence
• Reduce conflicts of interest
• Improve supervisory objectivity
• Enhance oversight of high-risk institutions

Lessons From the 2023 Banking Crisis

The GAO’s recommendations are heavily influenced by the banking turmoil that shook both traditional finance and the crypto industry in 2023.

The rapid collapse of three major U.S. banks with significant exposure to the digital asset sector raised serious questions about the effectiveness of regulatory oversight.

Banks That Collapsed

Silicon Valley Bank (SVB)

• Major technology and venture capital banking partner.
• Failed after a sudden depositor run.

Silvergate Bank

• One of the largest banking institutions serving crypto companies.
• Entered voluntary liquidation amid mounting losses.

Signature Bank

• A key banking partner for digital asset firms.
• Seized by regulators following a liquidity crisis.

All three institutions collapsed within days of one another in March 2023, following the fallout from the bankruptcy of cryptocurrency exchange FTX.

The failures triggered widespread market volatility and intensified calls for stronger supervision of both banks and digital asset markets.

Stablecoins and Tokenization Increase Regulatory Pressure

The GAO also noted that the crypto ecosystem has evolved significantly since the 2023 crisis.

Stablecoins have become increasingly important in global payments and trading, while tokenization of traditional assets is rapidly gaining traction among banks and financial institutions.

This convergence between traditional finance and blockchain technology means that risks are no longer confined to the crypto sector alone.

Instead, regulators are increasingly concerned about:

• Contagion risks between banks and crypto firms
• Stablecoin reserve management
• Operational risks from blockchain infrastructure
• Cybersecurity vulnerabilities
• Cross-border regulatory gaps

A New Era of Crypto Regulation

The GAO’s latest warning reflects a broader shift in Washington’s approach toward digital assets.

Rather than treating cryptocurrencies as an isolated industry, policymakers are increasingly viewing blockchain technology as a core component of the future financial system—one that requires the same level of oversight and coordination as traditional banking.

With stablecoin legislation advancing, tokenized assets expanding, and banks deepening their involvement in blockchain-based finance, the pressure on regulators to modernize their oversight frameworks is only expected to grow.

The message from the GAO is clear:

As blockchain transforms finance, regulators must evolve just as quickly—or risk falling behind the technologies they are tasked with overseeing.
