The First Stock Trades On the Blockchain Just Happened

Credit Suisse and Nomura just did the first stock trades settled via blockchain technology:

This week Credit Suisse cut some US equities trades with the Nomura-owned broker Instinet, using blockchain. This technology has been used before to verify other kinds of transactions. But these trades were a “first” because settlement occurred in hours and not the two days needed with America’s Depository Trust and Clearing Corporation, the industry-owned utility that normally settles stock trades.

This long settlement period is inefficient and costly:

“This is an incredibly inefficient way to operate,” Charles Cascarilla, Paxos’s chief executive tells me, pointing out that $15bn to $30bn of industry capital and twice as much liquidity are tied up in DTCC systems.

The two day settlement period was the key factor behind Robinhood stopping buy orders for GameStop shares earlier this year. The price had become so volatile that it could move against Robinhood a great deal in those two days. Given that, brokers insisted Robinhood post a large amount of colatteral. That expense was too great, so instead, Robinhood blocked buy orders for the stock. In a world where trades settled in hours via the blockchain, this would be much less likely.

However, blockchain technology is incredibly energy hungry. If we moved the massive volume of stock trading onto it, I suspect the energy needed might be prohibitive. I think instant, or at the very least faster, trade settlement is likely. But I expect that to happen via more standard computer systems, rather than blockchain technology.
