Bitcoin's Coinbase Premium Stays Negative for 51 Straight Days

Bitcoin's Coinbase Premium Index has held below zero for 51 consecutive days, with the latest reading at −0.10% as of Nov. 12, according to CoinGlass data. The streak began on Sept. 23 and marks the longest sustained period in which Coinbase has priced BTC below Binance's BTC-USDT market within the dashboard's current reporting window.

The index compares Bitcoin's price on Coinbase's BTC-USD pair against Binance's BTC-USDT pair. CoinGlass positions the measure as a proxy for buying and selling pressure in the US market relative to global markets. At −0.10%, the current reading is 0.04 percentage points less negative than the 30-day average of −0.14%, but still below the annual average of −0.06%. The monthly average sits 0.08 percentage points below the annual figure, placing the recent period deeper into discount territory than the longer reference window.

The one-year Z-score stands at −0.95, which CoinGlass labels within its normal range. Practitioners should treat the two metrics as distinct signals: one counts consecutive negative days, the other measures the reading against its historical distribution. Neither figure identifies counterparties or provides a dollar total for institutional flows.

What does the discount coincide with on the ETF side?

US spot Bitcoin ETFs recorded five consecutive outflow sessions through Nov. 11, losing roughly $1.44 billion across that stretch, according to SoSoValue figures. Net withdrawals on Nov. 11 alone reached $299.9 million, with BlackRock's iShares Bitcoin Trust accounting for $269.73 million and Grayscale's Bitcoin Trust losing $39.13 million. Morgan Stanley's Bitcoin Trust attracted $8.96 million, partially offsetting the outflows; the remaining products saw no net movement.

Despite the recent drawdown, cumulative net inflows since the funds launched in January 2024 stood at $55.1 billion. Combined net assets totaled $93.7 billion, with BlackRock's fund holding $58.71 billion — roughly 63% of the segment's assets. ETF creations and redemptions measure activity in investment products; the Coinbase premium measures relative exchange pricing. Neither dataset specifies investor identity or motivation.

Where is leverage sitting while spot demand lags?

In a Nov. 11 assessment, Bitfinex analysts described weak spot buying alongside futures positions that kept growing while Bitcoin fell. Open interest stood at 701,900 BTC, up 3.3% between Nov. 8 and Nov. 11, while the price declined 2.6%. After the US inflation release, open interest slipped just 0.2% despite approximately $729 million in liquidations — evidence, in Bitfinex's reading, that traders replaced closed positions almost immediately.

The analysts identified $75,717 as the average purchase price of coins held for fewer than 155 days. They estimated that 1.6 million BTC bought between $75,000 and $80,000 now sits underwater, exposing recent buyers to losses. In their assessment, those holders may sell into rallies approaching their cost basis until fresh spot demand returns.

Are derivatives markets still paying for protection?

Earlier comments from Bitget Wallet Research tied a sustained recovery to positive ETF flows and more balanced derivatives positioning. The analysts said the selloff had removed some speculative excess but that fresh demand remained insufficient.

CoinShares managing director Marc des Ligneris, in comments published Nov. 10, pointed to one-month options skew as further evidence of defensive positioning. Under the convention he cited, positive readings indicate investors paying more for downside protection via puts than for upside exposure via calls.

"This time it hasn't held so far: skew has risen again, showing that investors are still paying up to hedge," des Ligneris said.

What does this change for traders? The combination of a persistent US exchange discount, sustained ETF redemptions and underwater short-term holders suggests recovery depends on spot demand returning — and until ETF flows flip positive, rallies toward the $75,000–$80,000 cost basis face a ready supply of sellers.
