Fraud in credit unions: Tackling the threat in 2026

Tips on credit union fraud strategy in 2026
Fraud in credit unions is becoming increasingly complex, costly, and challenging to contain. From synthetic identity fraud to real-time payment risks, today’s fraud challenges go beyond account takeovers and check scams.
Protecting members and reducing institutional risk
According to the Federal Trade Commission (FTC), financial institutions reported fraud losses of over $12.5 billion in 2024, a 25% increase over the previous year. Statistics show that even though the financial institution is not at fault, victims of fraud are 31% more likely to end their relationship with the institution.
Heading into 2026, credit unions face a growing list of threats that demand attention. Fortunately, with proactive planning and targeted investments in people, processes, and technology, institutions can continue to protect members while strengthening their culture of compliance.
Staying on top of fraud is a full-time job. Let our Advisory Services team help when you need it.
Connect with an expertFraud tactics are evolving
Credit unions are now seeing traditional fraud schemes, such as social engineering, identity theft, and account takeovers, reemerging in new forms, enhanced by increasingly accessible technology. While the methods may look different, the objectives of fraudsters remain unchanged: gain unauthorized access and move funds before detection.
To maintain a strong fraud program in 2026, it’s essential to recognize how these familiar schemes are evolving:
- Synthetic identity fraud is getting harder to spot as criminals use advanced tools to create fake profiles that look real and pass through normal verification checks.
- Voice cloning and AI-generated speech are being used in call center fraud, enabling impersonators to bypass authentication by mimicking members’ voices with alarming accuracy.
- Deepfake video scams have emerged with fraudsters using video messages authorizing transactions that appear to originate from executives or business owners.
- Mule account activity is accelerating, with fraudsters utilizing instant payment platforms to transfer money through multiple accounts at a faster rate than ever before.
Real-time payment scams
As credit unions expand their use of real-time payments in 2026, it’s essential to acknowledge that faster transactions can also lead to increased fraud. Transactions clear almost instantly, leaving little time to investigate or reverse unauthorized activity.
Two scams, in particular, continue to raise concern among financial institutions.
- Push payment fraud, also known as authorized payment fraud, occurs when a fraudster tricks a member into willingly sending money to an account the criminal controls. Often, the scam involves creating a sense of urgency, such as pretending to be a relative in distress or a company demanding immediate payment. Because the member “authorized” the transfer, recovering the funds is more difficult.
- Business email compromise (BEC) remains a critical evolving threat. In these cases, fraudsters impersonate senior executives or vendors, often using compromised or spoofed email addresses, to request urgent wire transfers or payments. These messages can appear legitimate and are usually timed during vacations or leadership absences, making them difficult to detect.
Using AI to strengthen fraud detection
Programs that utilize artificial intelligence (AI) are changing how credit unions detect and prevent fraud. When used responsibly, AI can analyze account behavior in real time, flagging out-of-pattern activity and high-risk transactions before losses occur. AI is beneficial for detecting altered check amounts, elder fraud, or fraud schemes tied to organized regional groups.
However, with this innovation comes added responsibility. Regulators are closely monitoring the use of AI tools in financial services to ensure they are ethical, explainable, and free from bias. Members, too, want reassurance that their data is protected and that automation isn’t replacing human judgment. For credit unions, the goal should be to use AI to enhance, not replace, member service. Institutions that successfully balance automation with a human-in-the-loop approach will be better equipped to serve and protect their communities.
Strengthening internal controls
To address today’s evolving fraud schemes, credit unions don’t need to start from scratch. However, they do need to take a hard look at their existing controls and determine where updates are required. Strengthening foundational practices while adapting to new risks can significantly reduce the likelihood of loss and maintain member trust.
- Strengthen authentication processes: Traditional knowledge-based authentication is often insufficient in many cases. For high-risk or unusual interactions, consider adding layered verification, such as voice recognition or a second contact method, before approving changes or transactions.
- Invest in staff training: Your front-line teams are a critical part of your fraud prevention program. Ensure they understand how newer schemes can be used during routine member interactions. Regular training and scenario-based exercises can keep your team prepared.
- Collaborate with peer institutions: Fraudsters don’t target just one institution. Collaboration with other financial institutions is essential, such as 314(b) information sharing. Sharing information about scam trends, suspicious account activity, and known fraud patterns can help improve response times and better protect members.
Staffing gaps pose a hidden risk
While fraud tactics have evolved, many credit unions still face an internal challenge: staffing. Institutions continue to struggle with hiring and retaining experienced fraud professionals, particularly those who can manage complex investigations or handle alerts tied to instant payments. As workloads increase and expectations rise, this staffing gap can quickly become a liability.
Conducting a formal staffing assessment is a necessary step for credit unions in 2026. Institutions should examine not only their current team capacity but also opportunities for cross-training, succession plans, and contingency coverage. Some may benefit from partnering with third-party advisory teams to fill short-term gaps or offer specialized support during high-risk periods.
Member education is essential
Technology and staffing are only part of the solution. Fraudsters are increasingly bypassing institutions altogether and targeting members directly through phishing emails, spoofed texts, and fake payment requests. Proactive member education is essential.
Credit unions should regularly remind members to be cautious with unsolicited requests, especially those involving urgency or changes to payment information. Encouraging the use of strong passwords, multi-factor authentication, and transaction alerts can help members quickly identify unauthorized activity. Just as importantly, members need clear guidance on how to report suspicious behavior, and reassurance that their credit union is there to support them if something goes wrong.
Internally, institutions should continue to build layered defenses that include behavior-based transaction monitoring, account watchlists, and limits for new or unusual activity. Combined with external education, these steps form a stronger line of defense against fraud.
Looking forward: Build a resilient fraud response
The future of fraud in credit unions brings both challenges and opportunities. New payment rails, growing digital adoption, and evolving scams demand action, but they also present a chance to modernize programs and deepen member trust.
Credit unions that take a comprehensive approach, one that includes real-time detection, thoughtful AI adoption, strong staffing, and member education, will be best positioned to protect both their institutions and the communities they serve. Fraud prevention isn’t just about technology or rules. It’s about creating a program that evolves alongside the threats, without losing sight of what makes credit unions unique: their relationships.
