The Battle to Rewire Stock Trading the Crypto Way Is On

The stock market as we know it is on the brink of a transformation. The crypto industry has long touted the potential for the underlying blockchain technology to make trading more efficient, more liquid and 24X7. Now, firms including Robinhood Markets Inc. and Coinbase Global Inc. are pushing for “a speedy regulatory pathway” to begin that experiment, according to The Information. But at what cost?

There’s strong opposition to the idea from traditional financial firms such as Ken Griffin’s Citadel Securities, one of the top US market makers. Whoever wins this round, expect many more turf wars as the 20th-century financial system struggles to co-exist with 21st-century technology.

The crypto dream is to erase the boundaries between investors, customers, suppliers and employees — distinctions that are fundamental to financial regulation and incumbents’ business models — replacing them with fluid, multilateral, peer-to-peer cryptographic algorithms, embedding game theory incentives.

This is only an opening skirmish in that war. No one is talking about a transition to a distributed public ledger as the authoritative source of stock ownership — making stocks into cryptocurrency tokens. That may never happen, and in any case, it will not happen soon.

What Robinhood and Coinbase are suggesting is more like an exchange-traded fund. One proposal is for special-purpose entities — sponsored by these companies and others — to buy the stock in the current system and sell interests in those shares to individuals, and trade those interests on a blockchain. The legal proof of stock ownership would remain with the complex existing system.

This is similar to an ETF, except that the tokenized stock would trade on a cryptographically managed exchange rather than on existing exchanges. There are other potential structures but all of them involve individual investors trading on a blockchain for tokens that represent indirect ownership interests in the underlying stocks.
