Can Rising Bank Interest Rates Impact Stablecoins' Growth?

Understanding Stablecoins and Bank Rates

Stablecoins, a type of cryptocurrency designed to maintain a stable value, are often pegged to traditional currencies. Recent research by the Bank for International Settlements (BIS) indicates that slight increases in interest rates offered by banks could slow the growth of these digital assets.

The study conducted by Rashad Ahmed and Iñaki Aldasoro utilized data from American markets spanning from January 2019 to June 2025. They explored factors such as policy rates, bond yields, and stock market volatility in relation to stablecoin performance.

How Interest Rates Affect Growth

According to the findings, an increase of just one basis point (0.01 percentage point) in bank deposit rates can lead to a significant reduction in stablecoin growth. Over a ten-week period, growth rates may dip from approximately 15% to 12% on average, and even lower to 6% under different assumptions.

This decline is attributed to how bank rates respond to market changes. While deposit rates may remain steady during low-interest periods, they can adjust notably when these rates surpass certain thresholds. This responsiveness allows researchers to gauge how higher rates correlate with stablecoin growth.

Differential Responses Between Stablecoins

Interestingly, the study reveals a variance in how different stablecoins react to these interest rates. Circle’s USDC appears to be more affected compared to Tether’s USDT. The researchers believe this difference is largely due to USDC's stronger connection to American users.

Moreover, the trends observed do not suggest a simple correlation across the entire cryptocurrency market. Additional analyses did not find similar links between stablecoins and the growth of other digital currencies.

Notably, a brief from the Federal Reserve mentions that funds flowing into stablecoins can eventually find their way back as deposits held by stablecoin issuers. Consequently, while the distribution of deposits may change, it does not necessarily mean that bank funds are dwindling.

Limitations of the Study

However, it is essential to interpret these findings cautiously. The study does not provide clear evidence of actual decreases in bank deposits or confirm a contraction in credit. Additionally, it focuses on a specific period characterized by high rates. Factors such as yield-bearing stablecoins and tokenized money market funds could further complicate the competitive landscape.

Regulatory discussions are also ongoing. The Federal Reserve recently proposed a timeline to address stablecoin reimbursements, indicating a growing scrutiny over these digital assets. In the meantime, bank representatives have warned of the potential for substantial sums migrating away from traditional bank deposits to stablecoin alternatives.

Conclusion: The Competitive Edge of Banks

Ultimately, banks have a clear strategy to remain competitive: enhancing the returns on savings. The competition between stablecoins and traditional banking focuses not just on technological advancements but also on the overall yield they can provide to those holding liquid assets.

As the financial landscape continues to evolve, the interplay between stablecoins and traditional banking will require ongoing observation and analysis to fully understand the implications for both sectors.
