Facebook Inc’s move in 2019 to introduce its own stablecoin Diem, then known as Libra, raised concerns among governments and central banks that a major payments competitor could emerge overnight.
“We need to manage risks to competition,” John Glen told a City & Financial conference.
“There is the potential for some firms to swiftly achieve dominance and crowd out other players, due to their ability to scale and plug into existing online services,” Glen said.
“We believe the case for intervention in the wider cryptocurrency markets is less immediately pressing.”
Stablecoins such as the planned Diem, which is now run by an association that includes Facebook and currently seeking approval in Switzerland, are designed to avoid the volatility typical of cryptocurrencies like bitcoin.
Several countries, including France, have suspended flights to and from Brazil due to fears over the more contagious coronavirus variant spreading there.
