Funding Rate Dispersion — Z-Score
Z-score of the cross-exchange funding rate dispersion. High dispersion flags venue-specific stress or arbitrage windows; near-zero dispersion indicates a converged consensus across markets.
What is it?
Cross-exchange Bitcoin perpetual funding rate dispersion measure, normalised as z-score over a 90-day rolling window. Dispersion is defined as the standard deviation of simultaneous funding rates across the 10 largest perpetual pairs (Top 7 exchanges plus Bitget, MEXC, Gate.io). Formula: dispersion_t = std(funding_rate_i,t for i in the 10 exchanges), then z-score is computed over previous 90 days: z_t = (dispersion_t − mean_90d) / std_90d. When dispersion is high relative to its 90-day baseline (z > +2σ), it indicates exchanges diverge strongly from each other (typically arbitrage opportunity or extreme regime indication). When low (z < -2σ), it indicates abnormal convergence (potentially 'calm before storm'). Coinalyze source, 24h Postgres cache.
How to read
Y-axis: z-score value, typically bounded between -3 and +3 standard deviations. X-axis: daily time. The main curve traces the z-score evolution. The horizontal zero reference line marks the 90-day average dispersion level. Coloured threshold bands delimit regimes: normal zone (-1σ < z < +1σ) in transparent grey, notable zone (1σ < |z| < 2σ) tinted green or red depending on the sign, extreme zone (|z| > 2σ) tinted more strongly. Vertical markers highlight major historical regime shifts (FTX, halving, spot ETF). The BTC price overlay (right Y-axis, toggleable from the toolbar) enables crossing dispersion with price movement.
Key zones
A dispersion z-score > +2σ has historically marked significant arbitrage opportunity phases (funding diverges enough between exchanges for a delta-neutral cross-venue long/short strategy to generate non-trivial return after fees). Conversely, a dispersion z-score < -2σ (abnormal convergence) has frequently preceded macro regime-shifts (exchanges 'agree' on the eve of a disruptive event). The -1σ to +1σ zone corresponds to the normal regime of post-2024 mature perpetual market. Historically extreme readings (z > +3σ) are rare and have often coincided with technical incidents (exchange downtime, oracle issue, temporary dislocation).
What to observe
Priority patterns to watch: (1) z-score crossing +2σ for ≥3 consecutive days — durable cross-venue funding arbitrage indication (user-configurable Performance alert); (2) z-score plunging < -2σ for ≥3 days — abnormal convergence, watch for potential regime-shift in 7-14 days; (3) divergence with Layer B TFPI composite — if TFPI is in neutral zone but dispersion in extreme zone, it suggests directional pressure is weak but market is fragmented between venues (different quality indication than directional consensus); (4) correlation with BTC movement — dispersion tends to explode around extreme macro events (FOMC surprise, record ETF flows, geopolitical event).
Historical context
Notable documented episodes: April 2021 (dispersion z-score reaches +2.5σ for several days before May Elon Musk correction, exchanges strongly diverged on long leverage cost), 19 May 2021 capitulation (dispersion z-score plunges to -2σ then brutally rises to +3σ during cascade, temporary dislocation signature), November 2022 FTX collapse (dispersion z-score at +3σ+ for several days, some exchanges remained extreme while FTX became inoperative), January 2024 post-spot-ETF (moderate dispersion +1σ to +1.5σ for several weeks, reflecting arbitrages between US regulated and offshore venues), August 2024 Yen carry unwind (dispersion z-score at +2σ during cascade, divergence between Asian exchanges in panic and calmer US exchanges).
Expert notes
The 90d z-score is deliberately shorter than TFPI's (adaptive) because dispersion is more volatile and adaptive to recent regimes — 'normal' dispersion in 2024 bull market is not the same as 2022 bear market (market structure effects). For exhaustive cross-layer Trinity reading, systematically cross-reference with: (1) TFPI Trinity Funding Pressure Index (Layer B z-score adaptive composite) for aggregated directional context; (2) MVRV NUPL on-chain for cycle macro regime; (3) 4Y cycle position. This Performance tier metric carries user-configurable Discord/email alert: z-score threshold > +2σ over ≥3 consecutive days triggers notification. The alert is complementary to TLOI Performance which carries liquidation cascade alerts.
Common mistakes to avoid
Common mistake: interpreting high dispersion as an automatic price reversal indication. NO — dispersion measures cross-venue market fragmentation, not BTC price direction. High dispersion can accompany either bullish trend (Tier 1 exchanges maintain high funding while Tier 2 regionals capitulate) or bearish trend. Always cross-reference with TFPI to qualify direction. Another trap: confusing dispersion (this metric) with average funding amplitude (directional pressure indication). High dispersion does not imply extreme average funding — one can have +3σ dispersion with average funding close to zero if exchanges diverge strongly symmetrically (+0.05% Binance vs -0.05% Hyperliquid = average 0 but high dispersion).
