Real Interest Rates & Stablecoin Markets
· Updated daily
As of Jun 2026, the US 10-year real interest rate stands at +2.14% — nominal Treasury yield (DGS10) of 4.45% minus 10-year breakeven inflation of 2.31%. The real rate is held as the constant macro signal on this page; the stablecoin indicator it is compared against is selectable from six choices (market cap, velocity, USDT and USDC dominance, Supply Shock Index, and Issuer Theil). Real rates are the structural opportunity cost of holding stablecoins over T-bills — when real rates rise, T-bills genuinely reward capital; when they fall or turn negative, on-chain dollar yield collapses the carry. The 2022–23 hike cycle drove the real rate from roughly −1% to +2.5% — the primary mechanism behind the stablecoin supply contraction from $180B to $130B (BIS Working Paper 1068, 2023). Switching the Compare-Against selector tests whether velocity, dominance, or concentration responded to the same shift.
Stablecoin Market Cap vs 10Y Real Rate
Total stablecoin market cap (left axis, green) overlaid with the 10Y real rate (right axis, blue dashed). The dashed red line marks zero — above it, T-bills genuinely compete with on-chain yield; below it, stablecoins have a structural advantage. Regime bands mark each Fed policy period. Use the Compare against selector above to swap the left-axis indicator.
What Drives the Real Rate — Nominal Yield vs Breakeven Inflation (Full History)
10Y nominal Treasury yield DGS10 (blue) vs 10Y breakeven inflation T10YIE (amber dashed), full history from Jan 2020. The shaded fill is the real rate: the gap between the two lines. When breakeven inflation rose above nominal yields in 2020–22, real rates turned negative — the structural driver of the stablecoin expansion phase.
The four regime boxes below describe how stablecoin market cap has moved through each real-rate regime — the most documented channel (BIS WP 1068, 2023). When you switch the Compare against selector, the chart updates and the underlying mechanism shifts: velocity tests whether real-rate cycles change settlement intensity; USDT vs USDC dominance separates offshore from institutional flows; the Supply Shock Index makes regime-by-regime issuance flux explicit; Issuer Theil reveals concentration regime shifts. Use the 4-box framework as the rate-cycle backbone and switch comparisons to test which stablecoin indicator the real-rate signal is moving on a given day.
With nominal yields near zero and inflation rising, real rates turned deeply negative. T-bills yielded nothing after inflation. DeFi protocols offering 5–12% APY were substantially more attractive relative to near-zero T-bill yields. Total stablecoin market cap grew from ~$6B to ~$180B during this period (BIS WP 1068, 2023).
For macro investors: Negative real rates are the structural tailwind for stablecoin DeFi yields. When real rates are deeply negative, the carry trade into on-chain yield is at its most compelling.
As the Fed raised rates from 0% to 5.25%, real rates surged from approximately −1% to +2.5%. Inflation-adjusted T-bill yields decisively exceeded DeFi yields for the first time since 2018. Institutional capital rotated to money market funds. Total stablecoin market cap contracted from ~$180B to ~$130B — a relationship documented in BIS Working Paper 1068 (2023).
For CFOs and treasury teams: Based on the 2022–23 cycle, a sustained real rate above approximately +1% has historically been the point at which inflation-adjusted T-bill yields exceeded Aave USDC APY on a risk-adjusted basis.
Despite real rates remaining near their hike-cycle highs, stablecoin supply stopped contracting and began recovering from its ~$130B trough. Markets were pricing in an eventual cut cycle ahead — consistent with allocation responding to rate expectations as much as current levels. Supply grew from ~$130B to ~$160B during this regime.
For macro analysts: The recovery of stablecoin supply while real rates were still elevated at +2%+ illustrates why forward SOFR expectations are as important as the current real rate reading. For CFOs: Even at high real rates, cut expectations can justify early re-entry to stablecoin allocation ahead of the institutional consensus.
As the Fed began cutting rates in September 2024, nominal yields have declined while compressing the real rate. The opportunity cost of holding stablecoins over T-bills is narrowing, consistent with renewed expansion of stablecoin supply since mid-2024 to well above $200B.
For DeFi risk teams: Declining real rates historically precede renewed inflows to DeFi — monitor collateral utilisation and redemption pressure as capital returns. For regulators: Supply expansion in a declining real rate environment is structurally driven, not speculative issuance.
Real rate computation: 10Y real rate = DGS10 (10-year nominal Treasury yield) minus T10YIE (10-year breakeven inflation rate). Both series are published daily by the Federal Reserve and fetched from FRED. Coverage: January 2020 – present. Both series are denominated in percent per annum.
Breakeven inflation rate: T10YIE is derived from the yield spread between nominal 10-year Treasuries and 10-year TIPS (Treasury Inflation-Protected Securities). It represents the market's implied forecast for average CPI inflation over the next 10 years, not a survey or model estimate.
Forward-filling: Both DGS10 and T10YIE are not published on weekends or US federal holidays. Missing values are forward-filled from the last available observation to produce a continuous daily series. Data gaps are not interpolated — the last known value is carried forward.
Regime bands: Set to actual FOMC meeting dates — the four regimes (zero-rate, hike cycle, high-rate pause, cutting cycle) correspond to documented FOMC policy decisions, not model estimates. When the FOMC acts, bands are updated manually within one business day and the page is rebuilt. The current regime (cutting cycle, Sep 2024–present) remains open-ended until the next policy change.
Comparison indicators (left axis):
- Market Cap — daily sum of all tracked stablecoin market caps from CoinGecko snapshots (322 coins) plus extended history from DefiLlama. The standard rate-transmission lens (BIS WP 1068).
- Velocity — sum of daily on-chain trading volume (24h) divided by total market cap on the same day. Dimensionless ratio. Higher = more transactional use.
- USDT Dominance — USDT market cap as percent of total. Captures the offshore / non-US share of dollar-stablecoin demand.
- USDC Dominance — USDC market cap as percent of total. Sensitive to real-rate cycles because Circle's reserves are T-bill heavy.
- Supply Shock Index (SSI) — rolling 30-day percent change in total stablecoin market cap. The flux signal.
- Issuer Theil — Theil entropy of issuer market shares. Rises when issuance concentrates in fewer issuers.
What this page does not prove: Co-movement between the real rate and any comparison series is not causation. Stablecoin indicators are influenced by many drivers beyond real rates (regulation, offshore demand, DeFi-specific yield, EM dollarization). Use this page to test the real-rate-transmission hypothesis under each lens, not to attribute single causes.
