Bitcoin keeps losing ground when Wall Street opens as Coinbase discount deepens

The downward pressure on Bitcoin during US trading hours is intensifying, with BTC prices on Coinbase trading at a $64 discount compared to Binance, the largest global cryptocurrency exchange.

According to a CryptoSlate analysis of Binance BTC/USDT trading, Bitcoin has experienced a compounded loss of 3.24% during US stock-market hours since September 21. Meanwhile, prices outside of that trading window climbed by 6.07%.

During this timeframe, CryptoQuant’s Coinbase Premium Gap dropped to -$64, signaling either softer demand or heavier selling pressure on the US-centric exchange.

This trend aligns with observations from Glassnode, which notes that the American trading session has emerged as a driver of market pressure. However, because the losses were heavily concentrated during just two specific sessions—while exchange-traded fund (ETF) flows moved in opposite directions on those exact dates—claims of continuous institutional selling remain complicated.

Two sessions drove most of the decline

Out of 13 Wall Street cash sessions spanning from September 21 through October 7, Bitcoin declined during eight of them. Binance data analyzed by CryptoSlate indicates that the most severe drops happened on September 30 and October 2, when prices fell by 1.86% and 2.65% respectively throughout the 9:30 a.m. to 4:00 p.m. New York window.

When those two specific dates are excluded, the remaining 11 sessions actually yield a compounded 1.28% gain.

This distinction is crucial because the headline 3.24% loss can falsely imply a steady market deterioration rather than localized volatility. While the US session frequently showed weakness, the bulk of the cumulative negative impact originated from two sharp price drops instead of a consistent pattern of sell-offs.

The data also demonstrates that shifting the trading window alters the outcome entirely.

If the US session is measured from 9:00 a.m. instead of 9:30 a.m., it results in a compounded 4.94% loss through 4:00 p.m. across the same period. Beginning the window at 0 a.m. leads to a 5.41% decline.

Even after stripping away September 30 and October 2, these alternative timeframes still reflect losses of 0.16% and 1.68% respectively. Consequently, the positive 1.28% remainder relies heavily on the strict 9:30 a.m. opening boundary.

Price information from Coinbase highlights a similar overarching trend. Over the same timeframe, Bitcoin dropped roughly 4.85% between 9:00 a.m. and 4:00 p.m., and 5.36% from 10:00 a.m. to 4:00 p.m.

While the agreement between Binance and Coinbase reinforces the timing signal, it leaves the identity of the market participants unidentified.

Because Binance pairs Bitcoin with USDT while Coinbase measures it against the US dollar, neither platform discloses whether the sellers are American institutions, retail traders, market makers, or international investors operating during US business hours.

Glassnode reported that Bitcoin’s net gains since September 21 have primarily taken place outside of US hours, marking a reversal from an earlier period when American trading times played a major role in driving the asset upward.

ETF flows fail to identify the seller

Fund flows present the most significant obstacle to a straightforward institutional-selling hypothesis.

US spot Bitcoin ETFs registered $148.7 million in net outflows on September 30, which coincided with the initial major drop during the US session. However, just two days later, these funds drew in $189.9 million even though Bitcoin dropped by 2.65% during Wall Street trading hours.

This discrepancy indicates that ETF investors by themselves cannot account for the weakness seen during these sessions.

Outflows intensified on October 7, with the financial products logging $484.9 million in net withdrawals. This demonstrates that fund demand has occasionally softened, yet daily volume figures still fail to reveal precisely when the underlying Bitcoin was liquidated or which cohort of investors drove prices down.

The operational mechanics of redemptions introduce another variable. Following regulatory approval for in-kind creations and redemptions for crypto ETFs in 2025, withdrawals can entail transferring Bitcoin directly rather than forcing an immediate cash sale on the open market.

Therefore, the Coinbase discount functions more as a supportive indicator rather than definitive proof of widespread institutional selling. Although a sustained negative premium points to softer pricing on a platform heavily utilized by US investors, it cannot pinpoint the beneficial owners behind specific transactions.

Upcoming trading sessions will test whether this market behavior is becoming permanent.

Should Bitcoin continue losing value throughout Wall Street hours while the Coinbase discount stays deeply negative alongside expanding ETF outflows, the argument for a prolonged decline in US demand will gain traction.

Conversely, a recovery in US-session returns unaccompanied by a rebound in ETF flows would suggest alternative drivers, pointing potentially toward market makers, derivatives positioning, or other entities supplying Bitcoin during the American business day.

?Frequently Asked Questions

01Why does Bitcoin often drop when Wall Street opens?

Bitcoin frequently faces pressure during US market hours due to shifting liquidity dynamics, institutional trading behavior, and localized selling on US-focused exchanges like Coinbase.

02What is the Coinbase Premium Gap?

The Coinbase Premium Gap measures the price difference between Bitcoin trading on Coinbase (denominated in US dollars) and global exchanges like Binance (denominated in USDT). A negative gap indicates weaker demand or heavier selling pressure on Coinbase.

03Do ETF flows completely explain US session weakness?

No. While spot Bitcoin ETFs experience notable inflows and outflows, their daily activity does not always align directly with intraday price drops, suggesting other market participants or factors are involved.
