A Bank for International Settlements working paper has examined the relationship between bank deposit rates and stablecoin supply growth, finding that USDC exhibits a meaningfully stronger response to deposit rate movements than other major stablecoins, a result with implications for how analysts and policy watchers model stablecoin demand across interest rate cycles.
The BIS working paper centers on a straightforward research question: when bank deposit rates rise or fall, does the supply of dollar-pegged stablecoins expand or contract in response? The study's framing treats deposit rates as a competing yield benchmark, examining whether shifts in that benchmark correlate with observable changes in stablecoin market size. Because the paper is a working paper rather than a final publication, its findings carry the standard caveat that methodology and conclusions may be revised before formal publication.

The BIS, as the central bank for central banks, has published a growing body of research on crypto-asset markets; this paper extends that line of inquiry into the specific mechanics of stablecoin supply dynamics, distinguishing between the behavior of different issuers rather than treating the stablecoin sector as a single homogeneous asset class.

Bank deposit rates represent the yield a saver earns by holding cash in a traditional financial institution. When those rates are high, the opportunity cost of holding a non-yield-bearing stablecoin rises, as the holder forgoes interest income available in the conventional banking system. Conversely, when deposit rates compress, the relative attractiveness of stablecoins for payments, remittances, or DeFi activity is less penalized by foregone yield.

The BIS paper operationalizes this tension by measuring stablecoin supply growth as the dependent variable against changes in deposit rates, a framework that tests whether stablecoin holders behave in a manner consistent with rational yield-seeking, migrating toward or away from stablecoins as traditional banking alternatives become more or less competitive. Readers tracking stablecoin flows and foreign exchange market spillover effects will recognize this rate-sensitivity question as a recurring structural issue in cross-border capital allocation.
The paper's most notable reported finding is that USDC demonstrates a stronger response to deposit rate changes than the comparison group of stablecoins examined. The paper does not, based on the available summary, specify the exact coefficient size, the full comparison cohort, or the precise measurement period, so the magnitude and direction of the USDC differential should be understood as reported at the working paper stage pending peer review.
The finding invites structural hypotheses, though the paper's summary does not confirm a single explanation. USDC's user base skews toward regulated, institutional, and U.S.-domiciled activity, a composition that may amplify sensitivity to domestic deposit rate benchmarks relative to stablecoins more commonly used in emerging-market remittance corridors or on networks where the primary driver of demand is transaction throughput rather than yield arbitrage.
For analysts and institutional participants, the paper adds quantitative texture to a relationship that has been discussed qualitatively since the Federal Reserve's 2022-2023 rate hiking cycle, during which aggregate stablecoin supply contracted even as on-chain activity remained active. The BIS framing suggests deposit rates deserve explicit inclusion in any supply model rather than being treated as background noise. Researchers following enterprise stablecoin adoption may find the USDC-specific result particularly relevant as institutional card and payments infrastructure continues to expand.
The paper's status as a working paper is the primary caveat: conclusions have not been subjected to final peer review, sample periods and econometric specifications may shift, and the BIS itself notes that working papers reflect the views of individual researchers rather than official BIS policy positions. Any use of the findings for market positioning or regulatory modeling should be conditioned on reading the full methodology section, which will specify the deposit rate series, stablecoin supply aggregation method, and lag structure used.
The next concrete milestone to watch is formal publication or an updated working paper version, which would either confirm or revise the USDC-differential result and potentially extend the analysis to newer stablecoins that have gained significant share since the study's apparent data window closed.
The paper analyzes whether changes in bank deposit rates are associated with changes in stablecoin supply growth, treating the deposit rate as a competing yield benchmark that may attract or repel capital from the stablecoin market depending on its level.
According to the paper's reported findings, USDC exhibited a stronger response to deposit rate movements than other stablecoins in the comparison group. The specific magnitude and the full list of comparison stablecoins have not been confirmed in the available summary.
No. The paper is a working paper subject to revision, and a documented correlation between deposit rates and past stablecoin supply changes does not constitute a predictive rule for future market behavior. Rate sensitivity can shift as issuer composition, user demographics, and DeFi yield alternatives evolve.
The paper does not confirm a causal mechanism in the available summary. Analysts have hypothesized that USDC's concentration among U.S.-regulated and institutional holders may make its supply more sensitive to domestic banking rate benchmarks, but this remains an inference rather than a stated finding of the paper.
