The Bitcoin price continues its descent deep into red territory, as investors increasingly tread the capitulation path. Interestingly, a recent on-chain analysis has been carried out, which dives into the underlying factors that typically control Bitcoin’s December price action.

Coinbase Premium Suddenly Flips Into Negative Territory: Why This Is Important

In a QuickTake post on the CryptoQuant platform, crypto education institution XWIN Research Japan reported that the Coinbase Premium Index metric has recently seen a sharp nosedive. For context, this metric measures the price difference between Bitcoin on the Coinbase (USD) market and Bitcoin on other major global exchanges (such as Binance), or the USDT market. By doing so, it reflects the buying or selling biases of US investors and helps derive insights regarding their behavior.

According to the crypto research institute, the decline started around the late period of November, into early December. Because this decline correlates with an also sharp fall in the Bitcoin price, the apparent sentiment shift among investors from the US appears to be the source of the bearish pressure seen early in the month.

Interestingly, there are historical events that parallel the aforementioned scenario. Typically, December witnesses weaker readings from the Premium when compared to its performance throughout the year. The readings are often near or below zero “largely due to year-end rebalancing and tax-loss harvesting by US institutions and individuals,” XWIN Research highlights.

However, there have been slight deviations from this recurrent pattern. In 2018 and 2022, the Premium saw deep dives into negative zones, as the market was under significant stress in these periods. On another hand, 2020 and 2023 saw positive readings from the Premium, positively correlating with the ongoing bull-market momentum at the time.

XWIN Research Japan, however, made it worthy of note that this year’s scenario has its own “unique twist.” Notably, although the Coinbase Premium began in December with a negative, it has refused to maintain this state. Instead, the analytics platform reports that there was an almost immediate rebound not just into neutral levels, but back into positive territory. 

Because this sharp reversal took place within just a few days, it becomes apparent that the Bitcoin market may have seen the last strengths of extant bearish pressure. Interestingly, historical data reveal that such moves as the market has seen often precede price stabilization, or even short-term recoveries. Thus, if history is anything to go by, the Bitcoin price could be close to a local bottom, after which its recovery might follow.

Ultimately, XWIN Research points out that the stabilization, or sustained downturn, of the Bitcoin price depends mostly on “upcoming US capital flows, derivatives positioning, and premium trends.” At press time, Bitcoin holds a valuation of $89,321, with no significant movement since the past day.
