The exchange stablecoins ratio (ESR) and stablecoin supply ratio (SSR) provide important insight into Bitcoin’s liquidity and potential buying power. ESR measures the proportion of stablecoins relative to Bitcoin exchange reserves, serving as a gauge of spot liquidity.
A low ESR reflects limited immediate buying power, while a high ESR points to abundant capital waiting to move into Bitcoin. SSR compares Bitcoin’s market cap to the total stablecoin supply, showing the relative strength or weakness of stablecoin-driven demand. Together, these two metrics outline the strength of liquidity support behind Bitcoin’s price.
In 2025, ESR continued its decline, reinforcing a broader trend that began in 2023. At the beginning of April, the ESR stood around 0.000056, gradually falling to 0.000053 by month-end. This marks some of the lowest ESR levels seen to date, reflecting a shortage of stablecoins relative to Bitcoin reserves on exchanges. Historically, markets with a suppressed ESR are more vulnerable to downside shocks and less capable of supporting strong upside moves without external capital inflows.

Stablecoin supply ratio increased sharply throughout April. SSR climbed from 12.8 at the start of the month to 15.9 by the end, returning to levels last seen in February. This increase reflected a weakening in stablecoin purchasing power relative to Bitcoin’s market capitalization. A high SSR historically meant a reduced ability for stablecoin flows alone to sustain large rallies. The stagnant SSR in April confirmed that the rally above $90,000 was not built on strong stablecoin inflows or new speculative demand from sidelined cash.

Despite this backdrop, Bitcoin’s price remained stable between $91,000 and $95,000 across April, closing the month near $95,000. Price stability in the absence of strong stablecoin support points to underlying strength elsewhere in the market. Without significant material inflows of stablecoins, Bitcoin’s resilience likely stemmed from increased ETF inflows and long-term holders reducing their sell pressure.

The combined behavior of ESR, SSR, and Bitcoin’s spot price reveals a supply-constrained environment rather than one fueled by new demand. A falling ESR limited the capacity for stablecoins to drive prices to the upside.
A persistently high SSR showed that the broader stablecoin base was not expanding fast enough to lift Bitcoin’s price materially. However, BTC kept rallying, suggesting that the support structure shifted toward institutions, ETFs, and the withdrawal of sell-side liquidity rather than the arrival of new buyers.
No notable increase in stablecoin exchange inflows occurred during April. Similarly, the SSR did not break lower, which would have indicated expanding stablecoin-driven buying power. Retail demand through stablecoins remained absent. Bitcoin’s resilience was therefore supported by factors external to stablecoin liquidity, with ETF allocations and passive spot accumulation doing the heavy lifting.
The combination of low ESR and high SSR implies that Bitcoin’s price was mainly supported by existing spot demand, ETF inflows, or longer-term holders reducing selling, rather than an influx of new stablecoin liquidity typically seen in strong retail-driven rallies.
There were no signs of a substantial short-term inflow of new capital from stablecoins during April. If Bitcoin attempted to break higher from $95,000, the current structure would require either increased external buying, such as additional ETF flows or direct fiat inflows, or a sudden spike in stablecoin deposits to exchanges.
