A recent letter by Interactive Brokers, reported by bitcoin.com, raises questions about the potential impact of bitcoin futures on the stability of the economic world at large.

Earlier this month, popular exchange CME announced plans to unveil bitcoin futures by the end of 2017. (See more: Could Bitcoin Futures Help Limit Volatility?) Bitcoin futures would allow investors to participate in the cryptocurrency market without having to buy into the tokens themselves.

There has been speculation that the new product may help ease volatility in the digital currency space. Cryptocurrency investors responded by promptly pushing bitcoin prices to new highs. (See also: Bitcoin Price Sets Another High By Crossing $8,200.)

And yet, there are others who are not so sure that introducing cryptocurrency futures is a great idea for the broader economy.

Desire to Keep Products Separate

Interactive Brokers is one of Wall Street's primary broker clearing service providers. On November 14, the organization's chairman, Thomas Peterffy, published a missive in the Wall Street Journal.

"This letter is to request the Commodity Futures Trading Commission [CFTC] require any clearing organization that wishes to clear any cryptocurrency or derivative do so in a separate clearing system isolated from other products," Peterffy wrote. He also suggested that isolating bitcoin futures would help reduce the risk of "[destabilizing] the real economy."

Peterffy explains that if CME "clears a cryptocurrency together with other products, then a large cryptocurrency price move that destabilizes members that clear cryptocurrencies will destabilize the clearing organization itself and its ability to satisfy its fundamental obligation to pay the winners and collect from the losers on the other products in the same clearing pool. Cryptocurrencies do not have a mature, regulated and tested underlying market."

Volatility Is the Concern

It seems Peterffy's primary concern is the volatility of the digital currencies space. As interest in cryptocurrencies have skyrocketed over the past year, so too have their price fluctuations become increasingly dramatic. (See more: Why Is Bitcoin's Value So Volatile?)

In the past two weeks, for example, bitcoin hit a new high price point of more than $7,700 per coin before tumbling by more than 25% in the span of roughly 24 hours.

Peterffy has pointed out that cryptocurrency "products and their markets have existed for fewer than 10 years and bear little, if any, relationship to any economic circumstance or reality in the world."

While Peterffy's letter makes his position clear, it appears the broader cryptocurrency world is not slowing down anytime soon. Digital currencies are occupying larger and larger market caps as time goes on, in spite of frequent warnings that the entire space could be a bubble about to collapse. Should bitcoin futures become a reality, this may only push the markets higher and higher.
