Stablecoin Flows - Buying Power on Standby

2026-01-287 min read read

What are Stablecoins

Stablecoins are cryptocurrencies pegged 1:1 to fiat currencies like the US Dollar (USD). With virtually no price volatility, they serve as "cash" within the cryptocurrency market.

Major stablecoins include:

StablecoinSymbolIssuerCollateral TypeMarket Cap Rank
TetherUSDTTether LimitedFiat/Treasury bonds1st (among stables)
USD CoinUSDCCircleCash/Short-term treasuries2nd
DAIDAIMakerDAOOver-collateralized crypto3rd
First Digital USDFDUSDFD121Fiat collateral4th

Analyzing stablecoin flows allows you to gauge the scale of buying power waiting in the market. This is why stablecoins are important in on-chain analysis.


Why Stablecoin Flows Matter

Stablecoins = Crypto's Cash

Just as traditional finance investors sell stocks and hold cash, cryptocurrency investors sell Bitcoin or Ethereum and convert to stablecoins. Therefore, stablecoins' total supply and location are crucial data revealing market participants' positions.

Meaning of Exchange Stablecoin Balances

ChangeMeaningMarket Impact
Exchange stablecoin increaseBuying power inflowBullish signal
Exchange stablecoin decreaseBuying power outflowBearish or already deployed
Total supply increaseNew capital entering marketMedium-long term bullish signal
Total supply decreaseCapital leaving marketMedium-long term bearish signal

When an investor purchases USDT with fiat and deposits it to an exchange, it's like "loading ammunition." Having lots of stablecoins on exchanges means they're ready to buy Bitcoin at any moment.


Stablecoin Dominance

Stablecoin Dominance represents the proportion of stablecoins within total cryptocurrency market cap.

Interpretation Principles

Dominance LevelMeaningMarket State
High (>10%)Investors maintaining high cash allocationWait-and-see / Bearish
Medium (5-10%)Appropriate cash holdingsNeutral
Low (<5%)Most capital deployed in risk assets (BTC, ETH, etc.)Bullish / Potentially overheated

Contrarian Perspective

High stablecoin dominance paradoxically means abundant buying power. When everyone holds cash and watches, this capital can flow in rapidly if the market rebounds. Conversely, extremely low dominance means most capital is already deployed and additional buying power is limited.

Stablecoin dominance has similar contrarian logic to the Fear & Greed Index. When high, it may actually be an opportunity; when low, it may actually be risky.


Stablecoin Supply Ratio (SSR)

SSR (Stablecoin Supply Ratio) is Bitcoin's market cap divided by total stablecoin market cap.

SSR = BTC Market Cap / Stablecoin Market Cap

SSR Interpretation

SSR LevelMeaningMarket Impact
HighLow stablecoin relative to BTC market capLimited buying power. BTC upside may be constrained
LowHigh stablecoin relative to BTC market capAbundant buying power. Strong BTC upside potential
Declining TrendStablecoins growing faster than BTCBullish signal. Capital flowing in
Rising TrendBTC growing faster than stablecoinsPossible overheating. Capital inflow rate < price increase rate

When SSR is near historical lows, it means abundant standby capital in the market, interpreted as having further upside potential.


Stablecoins' Total Supply is a macro indicator showing the overall scale of capital flowing into the cryptocurrency market.

PeriodTotal Stablecoin SupplyMarket Situation
Early 2020~$5 billionPre-COVID, early market
Late 2021~$160 billionBull market peak, massive capital inflow
Late 2022~$130 billionBear market, some capital outflow
2024~$150+ billionRecovery phase, capital re-entering
2025~$200+ billionContinued growth

When total supply is continuously increasing, it means new capital keeps entering the market, suggesting a medium-long term bullish environment.


USDT vs USDC vs DAI: Each One's Characteristics

USDT (Tether)

  • Largest scale: Commands about 65-70% of stablecoin market
  • Asia-centric: Primarily used on Asian exchanges like Binance
  • Supply increase = Global capital inflow signal: When USDT supply surges, interpreted as Asia-centric new capital flowing in

USDC (Circle)

  • US regulation-friendly: Primarily used on US exchanges, DeFi
  • Institutional preference: Compliance advantage makes it preferred by institutional investors
  • USDC increase = Institutional capital inflow signal: Suggests expanding institutional market participation

DAI (MakerDAO)

  • Decentralized stablecoin: Operated by smart contracts, no central issuer
  • DeFi activity indicator: DAI supply reflects DeFi ecosystem activity
  • Over-collateralized structure: DAI minted by depositing excess ETH etc. as collateral
StablecoinPrimary MarketWhen IncreasingWhen Decreasing
USDTAsia, GlobalGlobal retail capital inflowRetail exit
USDCUS, InstitutionalInstitutional capital inflow, positive regulatory environmentDeclining institutional interest
DAIDeFiIncreased DeFi activity, leverage expansionDecreased DeFi activity, deleveraging

Practical Application Strategies

Strategy 1: Confirm Buying Power on Standby

When exchange stablecoin balances increase while exchange BTC holdings decrease, the conditions of supply decrease + demand waiting are met. This is a bullish signal that upward price pressure is forming.

Strategy 2: SSR-Based Buy Timing

When SSR is near historical lows and the Fear & Greed Index shows extreme fear, abundant buying power exists while the market is depressed, suggesting a strong rally when it rebounds.

Track monthly changes in total stablecoin supply. Three consecutive months of increase confirms a capital inflow trend; if it turns to decrease, be cautious as this is an early capital outflow signal.

Combining with Other Indicators

CombinationInterpretation
Exchange stablecoin surge + Exchange BTC reserves decreaseSupply decrease + demand waiting. Bullish signal
SSR at low + MVRV < 1.5Undervalued + abundant buying power. Strong buy case
Stablecoin supply decrease + Active addresses decreaseOverall market contraction. Wait-and-see recommended
USDT surge + USDC surgeRetail + institutional simultaneous inflow. Strong capital flow
Stablecoin dominance at all-time high + Moving average supportMaximum cash allocation + technical bottom. Rebound possible

Cautions

Stablecoin Transfer ≠ Immediate Buying

Just because stablecoins flow into an exchange doesn't mean buying happens immediately. Standby capital may sit for days to weeks before being deployed to buy, or may be withdrawn again.

De-pegging Risk

De-pegging events where stablecoin price deviates from $1 can shock the entire market. The temporary USDC de-peg during the Silicon Valley Bank crisis in 2023 is a notable example. Always monitor the health of stablecoins themselves.

Regulatory Impact

If stablecoin regulations tighten in various countries, supply may contract. Be aware that regulatory environment changes can affect supply data.


Summary

Stablecoins are the "cash" of the cryptocurrency market, and analyzing their flows reveals the scale and location of buying power on standby. Exchange inflows signal buying preparation, total supply increases signal market capital inflow, and stablecoin dominance and SSR show the market's buying capacity. Understanding the different characteristics of USDT (global retail), USDC (institutional), and DAI (DeFi), and combining analysis with exchange reserves, MVRV, Fear & Greed Index and others enables more accurate reading of market supply and demand dynamics.
