Anonymous loan applications: A simple tech solution to reduce racial disparities in consumer credit

Can removing names from loan applications help to reduce racial discrimination in lending? Our recent research suggests that it can. Analyzing a unique experiment at a leading fintech platform in Singapore, we find that anonymizing loan applications substantially reduced racial disparities in both loan approvals and terms. After anonymization, high-income minorities benefited more than low-income minorities, suggesting increased lender reliance on objective credit risk measures.
 

The Problem: Persistent Racial Gaps in Credit Access

Access to credit remains unequal across racial groups globally. Minority borrowers often face lower approval rates and worse loan terms compared to majority applicants with similar financial profiles. Although various solutions have been proposed—from algorithmic lending to diversity in loan officers—many require significant infrastructure changes or face implementation challenges. A solution that has received considerable attention from policy makers is the removal of applicant names as a source of racially identifying information. While anonymizing applications by humans can be time-consuming and error-prone, the growing use of information technology in lending can achieve scalable and cost-effective anonymization. Fintech platforms can serve as intermediaries between lenders and applicants, verify applicants, and withhold applicants’ racial identities from lenders.
 

A Simple Solution: Anonymous Applications

We study the removal of applicant names from loan applications. When a leading online consumer loan platform in Singapore implemented this change in September 2021, it provided a unique opportunity to examine how anonymization affects lending decisions.

The platform connects borrowers with multiple licensed lenders simultaneously, allowing borrowers to compare offers. Initially, lenders could see the applicant names. After the change, the applications were anonymized during the initial screening phase, although lenders still verified identity in person before final loan approval.
 

Key Findings

The analysis revealed several important findings:

1. Large preexisting disparities. Before anonymization, minority applicants were 10% less likely to receive loan offers than otherwise identical majority (Chinese) applicants. Minority applicants also received smaller loans, shorter maturities, and higher interest rates.
2. Substantial impact. After anonymization, these disparities largely disappeared. The racial gap in offer probability was eliminated, and differences in loan terms were significantly reduced.

Figure 1 shows graphical evidence of findings 1 and 2. Before anonymization (to the left of month 0), minority applicants were less likely to receive loan offers. After anonymization (to the right of month 0), the racial gap in loan offers disappeared.

Figure 1: Impact of Anonymous Applications on the Racial Gap in Loan Offer Probability

^{Note: The figure shows how racial disparities in loan offer probability changed before and after implementing anonymous applications. Before anonymization (left side of month 0), minority applicants were less likely to receive loan offers compared to Chinese applicants with similar characteristics. After anonymization was implemented (right side of month 0), this gap disappeared, with minorities becoming marginally equally likely to receive offers. The shaded area represents the 95% confidence interval around the estimates. This striking change suggests that removing names from applications can effectively reduce racial disparities in lending.}

3. Benefits for high-income minorities. Although both low- and high-income minority applicants benefited from anonymization, the gains were larger for high-income minorities. This suggests that lenders began relying more on objective measures, like income, rather than demographic factors.
4. Persistent effects. Although lenders eventually learned applicants’ race during in-person verification, most of the benefits of initial anonymization persisted through final loan origination.

Why It Works

The effectiveness of anonymization likely stems from several factors:

• Reduced initial bias. By removing race-identifying information at the crucial first screening stage, anonymization helps to ensure that initial decisions are based on economic factors rather than demographic characteristics.
• Increased focus on fundamentals. When they are unable to see applicant names, lenders appear to put more weight on objective measures, like income.
• Scalable implementation. Unlike more complex interventions, name removal is straightforward to implement, especially on digital platforms.

Practical Implications

Our findings have important implications for policy makers and financial institutions:

1. For digital platforms. Fintech platforms can easily implement anonymization as a default feature. The growing shift toward digital lending makes this increasingly relevant.
2. For regulators. Policy makers might consider encouraging or requiring anonymous applications as a complement to existing fair lending regulations.
    

Looking Forward

The growth of digital lending creates new opportunities to implement anti-discrimination measures, such as anonymous applications. Although this is not a complete solution to lending disparities, our research suggests that simple technological changes can contribute toward meaningful progress in more equitable credit access.

As financial services increasingly move online, testing and implementing such straightforward interventions should be a priority for both private institutions and policy makers. The benefits of reducing discriminatory lending practices extend beyond individual borrowers to support broader economic inclusion and growth.
