IBIT NAV Premium Deviation vs 90-Day Baseline
Deviation of BlackRock IBIT's estimated premium to NAV from its own 90-day rolling mean, smoothed over 21 days and clipped at ±1.5%. The premium is computed against a NAV proxy built from the issuer-published NAV per share and the BTC spot price. A positive reading is not a premium in the strict sense: it only means the estimated premium sits above its own recent baseline.
What is it?
This metric tracks how far BlackRock IBIT's estimated premium to its net asset value (NAV) sits from its own recent baseline. The estimate compares IBIT's market close with a NAV proxy built from the issuer-published NAV per share and the BTC spot price. The raw premium is then expressed as a deviation from its own 90-day rolling mean, smoothed over 21 days and clipped at ±1.5%. The displayed series covers IBIT alone and no average across issuers enters the calculation. A positive value is not a premium in the strict sense: it says the estimated premium is above its own baseline, not that the fund trades above NAV.
How to read
The horizontal axis is time. The vertical axis is the deviation of IBIT's estimated premium from its own 90-day rolling mean, in percentage points. Zero is IBIT's own recent baseline, not a NAV alignment: a positive value means the estimated premium is above that baseline, a negative value below it. The series is smoothed over 21 days and clipped at ±1.5%, so the visible ceiling and floor are bounds, not observed extremes. The ±0.3% band is a reading reference. The BTC overlay can be toggled to compare these deviations with price volatility regimes.
Key zones
• Above +0.5%: estimated premium well above IBIT's own baseline • +0.1% to +0.5%: moderate positive deviation from the baseline • ±0.1%: deviation close to the baseline • -0.5% to -0.1%: moderate negative deviation from the baseline • Below -0.5%: deviation well below the baseline • ±1.5%: clipping bounds of the published series; values do not exceed them
What to observe
• Persistence of a deviation above or below the baseline rather than a single daily move • Transitions through zero as the estimated premium crosses its own baseline • Approach of the ±1.5% clipping bounds, which marks the limit of the published series • Confluence with daily flow metrics, read as context rather than as proof of a premium • Divergence with BTC price direction, which can move the NAV proxy and the market close differently
Historical context
Before 2024, Grayscale GBTC traded at persistent discounts of 30-40% from 2022 through early 2024 because its closed-end structure lacked a redemption mechanism. The conversion of GBTC to a spot ETF on January 11, 2024 closed that legacy discount in one trading session. Since then, creation and redemption arbitrage has generally kept major US spot ETFs close to NAV. This chart does not plot those absolute premiums: for IBIT alone it plots the deviation of the estimated premium from its own 90-day rolling mean, smoothed over 21 days and clipped at ±1.5%. The historical GBTC episode explains the mechanism, not the level of the plotted series.
Expert notes
The series measures IBIT against its own 90-day baseline, which removes the persistent proxy bias between the issuer NAV and the Trinity spot reference. Premiums of other issuers are not part of this chart. The 21-day smoothing suppresses timing noise between the 4pm ET reference rate and the on-chain spot close; the ±1.5% clip bounds the published values. Couple with the TEHS health score and the net flow Z-score for context. A positive reading must not be reported as a premium to NAV: it is a deviation above the baseline, and the true premium can remain negative.
Common mistakes to avoid
• Do not read a positive value as a premium to NAV: it only means the estimated premium is above its own 90-day baseline, and the true premium can be negative. • Do not read a negative value as a discount to NAV for the same reason. • Do not treat the ±1.5% bounds as observed extremes: they are clipping bounds of the published series. • Do not interpret a single daily move as an event: the series is smoothed over 21 days and measured against a moving baseline. • Do not extrapolate the legacy GBTC discount era to current spot ETFs: the structural mechanism is different. • Do not confuse this series with realized versus spot premium, a distinct metric.
