The BIS paper links the appeal of holding stablecoins to the opportunity cost of keeping funds in conventional bank accounts.
A paper from the Bank for International Settlements finds that higher bank deposit rates are associated with slower stablecoin growth, identifying traditional savings returns as a competitive force against dollar-pegged digital assets such as USDC and USDT.
What the BIS Finding Shows
The BIS paper links the appeal of holding stablecoins to the opportunity cost of keeping funds in conventional bank accounts. When deposit rates rise, the return available from traditional banking increases, making non-yielding stablecoins comparatively less attractive for users who might otherwise park dollar-denominated value on-chain.

Stablecoins and bank deposits serve overlapping functions as stores of dollar value, but they are not identical instruments. Bank deposits sit within regulated, insured systems and now offer meaningful yield in higher-rate environments. Stablecoins, by contrast, typically pass no yield directly to holders, though they remain accessible around the clock and move across borders without intermediaries.

The finding is relevant to regulators and market observers tracking stablecoin supply trends. As interest-rate conditions shift, changes in deposit yields become a variable worth monitoring alongside stablecoin issuance data. The European Banking Authority’s classification of Circle’s USDC as a significant e-money token under MiCA reflects growing regulatory attention to stablecoin issuers as near-bank entities, a framing that aligns with the BIS research treating deposit rates and stablecoin demand as linked variables.

Why Deposit Yields Affect Marginal Stablecoin Demand
The economic mechanism is straightforward: a user deciding where to hold idle dollar-equivalent balances faces a choice between a yielding deposit account and a stablecoin wallet. When deposit rates are low, the cost of choosing a stablecoin is minimal. When deposit rates climb, that calculation changes for users whose primary goal is preserving and growing dollar value rather than transacting on-chain.
Stablecoins retain utility that deposit accounts cannot replicate. They function as liquidity within decentralized finance protocols, settle transactions on blockchains such as Tron, and enable cross-border transfers without correspondent banking delays. These use cases persist regardless of deposit rate levels, which means the BIS finding applies most directly to marginal demand, specifically users holding stablecoins primarily as a savings substitute rather than for active on-chain activity.
Jurisdiction matters as well. In markets where access to formal banking is limited or deposit rates are low regardless of central bank policy, stablecoins may face less direct competition from traditional savings products. The BIS research frames deposit rates as one input into stablecoin demand, not the sole determinant.
What This Means for Stablecoin Adoption Trends
For anyone tracking stablecoin supply and usage data, the BIS paper adds interest-rate conditions to the list of macro variables worth monitoring. Rising deposit rates during tightening cycles could temper stablecoin growth even when on-chain activity remains healthy, while rate cuts could remove that friction and support renewed expansion in stablecoin supply.
The research should be read as analytical context, not a forecast. The BIS paper identifies a relationship between deposit rates and stablecoin growth; it does not predict which issuers will gain or lose market share, nor does it address protocol-level dynamics such as staking yields or lending markets that can offset the competition from bank deposits for on-chain participants.
The broader competition between traditional financial returns and digital-dollar demand is a theme that extends beyond stablecoins. Inflation and interest-rate dynamics shape capital allocation across asset classes, and the BIS finding positions stablecoins squarely within that broader macro framework rather than treating them as isolated from conventional monetary conditions.
Bitcoin’s fixed monetary policy, with its programmatic issuance schedule and halving-driven supply reductions, stands in deliberate contrast to this rate-sensitive environment. Stablecoins, by design pegged to fiat, inherit the same sensitivity to central bank policy that affects all dollar-denominated instruments, a structural distinction the BIS paper implicitly highlights by treating deposit rates as a meaningful lever in stablecoin adoption.
