Bitcoin futures open interest jumps by $1B: Manipulation or hedge?

Bitcoin News

Bitcoin’s (BTC) open interest on derivatives exchanges experienced a sudden surge of $1 billion on Sep. 18, prompting investors to question whether whales were accumulating in anticipation of the unsealing of Binance’s court filings.

However, a closer look at derivatives metrics suggests a more nuanced picture, as the funding rate did not exhibit clear signs of excessive buying demand.

The decision to unseal these documents was granted to the U.S. Securities and Exchange Commission (SEC), which had accused Binance of non-cooperation despite previously agreeing to a consent order related to unregistered securities operations and other allegations.

The open interest spiked to $12.1 billion while Bitcoin’s price concurrently increased by 3.4%, the highest point in over two weeks at $27,430.

However, investors soon realized that, aside from a comment by the Binance.US auditor regarding the challenges of ensuring full collateralization, there was little concrete information revealed in the unsealed documents.

Later in the day, Federal Judge Zia Faruqui rejected the SEC’s request to inspect Binance.US’s technical infrastructure and share additional information. Nevertheless, the judge stipulated that Binance.US must furnish more details about its custody solution, casting doubt on whether Binance International ultimately controls these assets.

By the end of Sep. 18, Bitcoin’s open interest had receded to $11.3 billion as its price dropped by 2.4% to $26,770. This decline indicated that the entities behind the open interest surge were no longer inclined to maintain their positions.

These whales were likely disappointed with the court’s outcomes, or the price action may not have unfolded as expected. In any case, 80% of the open interest increase disappeared in less than 24 hours.

Futures’ buyers and sellers are matched at all times

It can be assumed that most of the demand for leverage was driven by bullish sentiment, as Bitcoin’s price climbed alongside the increase in open interest and subsequently plummeted as 80% of the contracts were closed. However, attributing cause and effect solely to Binance’s court rulings seems unwarranted for several reasons.

Firstly, no one anticipated that the unsealed documents would favor Binance or its CEO, Changpeng “CZ” Zhao, given that it was the SEC that had originally requested their release. Additionally, the Bitcoin futures contract funding rate, which gauges imbalances between long and short positions, remained largely stable throughout this period.

If there had indeed been an unforeseen demand surge of $1 billion in open interest, primarily driven by desperate buyers, it’s reasonable to assume that the funding rate would have spiked above 0.01%. However, quite the opposite unfolded on Sept. 19, as Bitcoin’s open interest expanded to $11.7 billion while the funding rate plunged to zero.

With Bitcoin’s price rallying above $27,200 during this second phase of open interest growth, it becomes increasingly evident that, regardless of the underlying motives, the price pressure tends to be upward. While the exact rationale may remain elusive, certain trading patterns could shed light on this movement.

Market makers’ hedge could explain OI spike

One plausible explanation could be the involvement of market makers executing buy orders on behalf of substantial clients. This would account for the initial enthusiasm in both the spot market and BTC futures, propelling the price higher. After the initial surge, the market maker becomes fully hedged, eliminating the need for further buying and leading to a price correction.

During the second phase of the trade, there is no impact on Bitcoi price, as the market maker must offload the BTC futures contracts and purchase spot Bitcoin. This results in a reduction in open interest and may disappoint some participants who were anticipating additional buying fervor.

Rather than hastily labeling every “Bart” formation as manipulation, it is advisable to delve into the operations of arbitrage desks and carefully analyze the BTC futures funding rate before jumping to conclusions. Thus, when there is no excessive demand for leveraged long positions, an increase in open interest does not necessarily signify a buying spree, as was the case on Sep. 18.
