The National Association of Insurance Commissioners (NAIC) has suspended its use of investment risk designations following a cyber attack that compromised parts of its systems, the organization confirmed on Monday. The designations are a cornerstone of state insurance solvency regulation, directly influencing how much capital insurers must hold to meet obligations to policyholders.
What the suspension means for insurers and regulators
The investment risk designations — ranging from Class 1 (lowest risk) to Class 6 (highest risk) — are applied to insurers’ bond portfolios and other fixed-income assets. State insurance departments rely on these designations to apply risk-based capital (RBC) standards, which determine the minimum capital an insurer must hold. Without updated designations, regulators may need to rely on previous classifications or alternative methods to assess solvency, creating potential inconsistency across states.

The NAIC said in a statement that it detected the attack on its systems and immediately took steps to contain the breach, including suspending access to affected databases. The organization did not disclose the nature of the attack, whether any sensitive data was exfiltrated, or when full operations would resume.
Background on NAIC and the designation system
The NAIC is not a federal regulator but a standard-setting body composed of insurance commissioners from all 50 states, the District of Columbia, and U.S. territories. Its investment risk designations are published annually and are used by state regulators, rating agencies, and insurers themselves to gauge portfolio risk. The NAIC describes the designations as a “critical element” of the solvency monitoring framework.

The suspension comes at a time when cyber attacks on financial regulatory infrastructure are increasing. In 2023, the U.S. Securities and Exchange Commission faced a breach of its EDGAR filing system, and several state insurance departments have reported attempted intrusions. The NAIC incident underscores the vulnerability of the interconnected systems that underpin U.S. financial regulation.
Industry reaction and next steps
Insurance industry groups have expressed concern about the suspension’s impact on capital planning and regulatory filings. The American Council of Life Insurers (ACLI) said it is in contact with the NAIC to understand the scope of the disruption and the expected timeline for recovery. “Our members rely on timely and accurate risk designations for their capital management and reporting,” an ACLI spokesperson said.
The NAIC said it is working with cybersecurity experts and law enforcement to investigate the breach and restore affected systems. It advised state regulators to use the most recent available designations as a temporary measure. The organization plans to issue further guidance as the situation develops.
Frequently Asked Questions
What is the NAIC’s role in insurance regulation?
The NAIC is a standard-setting organization that helps coordinate insurance regulation across U.S. states. It develops model laws, conducts financial analysis, and provides tools like investment risk designations that state regulators use to oversee insurer solvency.
How do investment risk designations affect policyholders?
These designations help ensure insurers hold enough capital to pay claims even if their investments lose value. A disruption in the designation system could temporarily reduce the precision of solvency monitoring, but policyholder payouts are not immediately at risk.
Could this cyber attack lead to changes in how the NAIC operates?
It is likely. The incident may prompt the NAIC to accelerate cybersecurity upgrades, adopt more resilient data systems, and review its incident response protocols. Similar breaches at other financial regulators have led to system overhauls and increased investment in threat detection.
Are there alternatives to NAIC designations that regulators can use?
Yes. Some states and insurers use internal risk models or third-party ratings from agencies like Moody’s or S&P as supplementary tools. However, NAIC designations are the standardized benchmark used for regulatory capital calculations, so alternatives may not be directly interchangeable.
