Money at the Speed of Thought: How ‘Fast Money’ Will Shape the Future

In This Article:

Around 2008, an ambitious startup decided to dig a tunnel from Chicago to New York. It would be an arduous and expensive task, with a final price tag of $300 million. But the tunnel would move spectacularly valuable payloads at unprecedented speeds, and customers would pay handsomely for the privilege.

The tunnel was not, however, for a new highway, or a high-speed rail line, or a gas pipe. It would not move goods or people or raw materials. In fact, a tall person would have a hard time standing up in it.

Instead, the tunnel was intended to move just one thing: money.

Completed in 2010, Spread Networks’ new tunnel was home to a fiber-optic cable that sent trading orders from Chicago to New York a whole 3 milliseconds ahead of the next-fastest pathway. Marginal as it might seem, those 3 milliseconds would give the new cable’s users a crucial edge against their competition. The customers were then-trendy “high-frequency trading” investment firms, whose algorithmic strategies often reacted to the same set of signals. A 3 millisecond advantage meant getting better price tags on trading positions, again and again and again. At least in theory, it was a license to print money.

Ten years later, we’re entering a different era of monetary speed. By leveraging the internet and innovative blockchain technology, cryptocurrencies can move money around the world faster than legacy banking and payments systems, while also giving control directly to users instead of middlemen. That will have a huge number of implications for commerce, for globalization – and most of all, for investment.

What We Talk About When We Talk About Speed

You may have noticed a slight inaccuracy above: Spread Networks’ fiber-optic cable wasn’t really “moving money” between Chicago and New York. Instead, it was transmitting orders, and the traders using it presumably had trusted relationships, credit lines or other means to guarantee that they had the money to back those orders up.

This two-tier system is how the vast majority of money transmission works now. Think about the act of handing someone a paper check (for those outside of the retrograde U.S.A., let me Google that for you. Are you handing them “money”? Not at all. You’re handing them a promise to deliver money from your bank account. When they deposit it, their bank and your bank trade a fairly complex series of messages to confirm the money is available.

The money doesn’t actually move from one bank’s ledger to the other’s until that back-and-forth resolves to everyone’s satisfaction. That can be a good while after the check is deposited, much less after you gave it to your friend. An international transfer involves a still higher level of negotiation and confirmation before a transaction is well and truly “settled.”
