Stablecoin and central bank digital currency may offer the benefits of buying and selling with cryptocurrencies without the worrisome price swings.
Blockchain-driven transactions could benefit the ecommerce industry. Transaction fees should be low if they exist at all. Fraudsters would be flustered. Even consumers without bank accounts and credit cards could shop online.
But absent fluctuations in value, crypto payments are not feasible for most merchants.
Stablecoin is a cryptocurrency. But unlike Bitcoin or Ethereum, stablecoin has a fixed exchange rate tied to an external reference, such as the U.S. dollar, the euro, or a commodity, say gold or silver.
Stablecoins are issued by private companies but work like governments, expanding or contracting the money supply to maintain fixed exchange rates.
In the case of a stablecoin pegged to the U.S. dollar, the issuing company or organization would hopefully hold at least as many U.S. dollars as there are units of the stablecoin in circulation. If there was a run on the stablecoin, the issuer could therefore exchange them for dollars.
Central bank digital currencies are a public sector alternative to stablecoins.
China, Sweden, The Bahamas, Marshall Islands, and the Eastern Caribbean Currency Union have all released CBDCs for retail transactions.
In each case, the ledger or blockchain used to record and verify transactions is government-controlled, involving a central bank.
Thus a CBDC should be just as stable and safe as that government’s fiat currency, and a merchant or shopper could exchange a CBDC in confidence.
Several other nations are reportedly considering a retail CBDC. Again, these digital currencies could have the benefits of cryptocurrencies and the stability of, say, U.S. dollars.
Stability is important. Consider this example. In May 2010, a programmer named Laszlo Hanyecz paid 10,000 Bitcoin for a pair of Papa John’s large pizzas. At the time, Hanyecz was getting a real deal. The 10,000 Bitcoin had a street value of about $10. The pair of pizzas were worth double that.
Fast forward to October 12, 2021, and 10,000 Bitcoin are worth more than $562 million. That is insane volatility.
It is little wonder merchants are concerned. Sell a widget for a tiny percentage of a Bitcoin, exchange it for a handful of dollars, and tomorrow you could miss out on a fortune — or vice versa.
Tether is arguably the most popular stablecoin in the world. In October 2021, it had a market capitalization of almost $70 billion. And Tether is pegged to the U.S. dollar.
If Tether or similar stablecoins are to be used in ecommerce, merchants and shoppers must feel comfortable holding it so that its value and the U.S. dollar are in lockstep.
Critics have questioned Tether’s asset base. They argue that Tether’s holdings are not sufficient or visible enough to make it trustworthy.
Tether has responded by opening up its books.
Ironically, the controversy around Tether might hasten its use in online transactions.
Concerned about what would happen to a reference currency if a stablecoin failed, some governments, including the U.S., have started to consider regulating stablecoin, similar to controlling the domestic money supply.
That regulation could remove some of the advantages of using a stablecoin for online transactions. But it could also build consumer confidence.
