The Monetary Authority Singapore may reel back retail access to cryptocurrencies as part of current considerations for potential additional curbs.

The MAS is considering tightening crypto rules for retail investors by «adding friction» to mass access, according to managing director Ravi Menon in a speech published online. This includes the possible addition of suitability tests as well as restrictions on the use of leverage and credit.

Market volatility this year has led a number of crypto players in the city-state to suffer including exchange Zipmex and lender Hodlnaut. In the latest, fallen Singapore hedge fund Three Arrows’ co-founder Su Zhu reemerged in public to deliver an affidavit defending himself against liquidator claims.

Bans Won’t Work

Despite its concerns, Menon notes that a regulatory ban is not a viable option as it is «not likely to work». 

«The cryptocurrency world is borderless. With just a mobile phone, Singaporeans have access to any number of crypto exchanges in the world and can buy or sell any number of cryptocurrencies,» Menon said in the opening address of a seminar held today.

Singapore continues to rethink mass access to cryptocurrencies following guidelines issued in January to limit trading services providers from public promotion.
