Please correct me if I'm wrong but I don't think Binance has a license in Singapore.
Indeed they don't have a license at the moment, but as far as I know, from hundreds of crypto exchanges in Singapore, Binance which officially issued a license from a related party this year, it can be seen here:
https://www.reuters.com/markets/currencies/binance-affiliate-says-will-withdraw-singapore-licence-application-2021-12-13/Binance's Singapore unit was one of well over 100 cryptocurrency companies to apply for a license to operate in Singapore and had been allowed do business while its license request was being processed.
Singapore issued its first licences this year, including to a unit of southeast Asia's largest bank DBS (DBSM.SI), however dozens of others have been withdrawn or rejected.
Yeah, that's exactly what it is saying, specifically that Binance does not have a license to operate really. Binance, along with other companies, are operating because they are applying for a license and the government of Singapore is benevolent enough to allow them to operate while their license applications are still in the process. However, as the article says, dozens of license applications are already rejected or withdrawn possibly for failing to meet certain regulatory requirements.
For now, not sure exactly the motivation behind Binance's current shutdown there, maybe what is said by: @Husires, it could be, but it's not certain, for now my relatives there can only follow directions first, there is no clearer information as to why this happened.
Husires has a point. That's probably the reason why Binance is withdrawing its license application, because it cannot provide what the Monetary Authority of Singapore (MAS) is asking. That's precisely the same reason why Binance also withdrew its registration application with the UK's Financial Conduct Authority (FCA). They did not cooperate. They'd rather pull out their application than have themselves closely scrutinized by the authorities.
