Singapore's Monetary Authority (MAS), the country's central bank and financial regulator, has renewed its warning that cryptocurrency trading is unsuitable for the general public, following the reported hack of major exchange Binance in which approximately $6.3 billion in digital assets was transferred from wallets controlled by the platform. The authority urged consumers to avoid unregulated companies when dealing in digital assets.

The warning was issued on November 5 in response to questions from Lianhe Zaobao, a Singaporean newspaper. Alongside its renewed caution, MAS clarified that Binance is not authorized to provide regulated financial services in Singapore, and noted that even licensed crypto firms cannot eliminate losses stemming from the inherent risks of the market.

Reported $6.3 Billion Hack Renews Security Concerns

The regulator's latest statement follows reports that hackers transferred approximately $6.3 billion in digital assets from Binance-controlled wallets. The affected assets reportedly included Bitcoin, Ethereum, the stablecoins USDT and USDC, and several smaller tokens. The incident temporarily disrupted withdrawals and some trading services on the exchange.

The reported losses have renewed concerns about exchange security and about the risks of holding assets with centralized platforms, where customers rely on the operator's safeguards rather than on their own. The alternative, self-custody, shifts responsibility for safeguarding private keys directly to the holder, along with the risk of permanent loss if those keys are misplaced or compromised.

Binance's Regulatory Status in Singapore

MAS reiterated that Binance does not hold authorization to provide regulated financial services in the city-state. Crypto trading platforms operating there fall under the Payment Services Act, under which MAS licenses digital payment token service providers — a regime MAS has framed around anti-money-laundering and technology risk controls rather than protection from market losses. The exchange previously operated Binance.sg, a Singapore-specific platform, and applied for a local license in 2021, but later withdrew the application. Binance.sg stopped operating in 2022.

In September 2021, the authority placed Binance on its Investor Alert List, saying consumers might mistakenly believe the exchange held a Singapore license or regulatory approval. Companies on the list cannot conduct regulated financial services without the necessary licenses, and MAS publishes the list so consumers can check an entity's status before transacting. Binance.com, however, remained accessible to Singaporean investors after the local platform closed.

Why MAS Says Crypto Trading Carries Risks

The authority emphasized that regulatory approval does not guarantee protection against cryptocurrency losses. Licensed providers must comply with regulatory requirements, but those safeguards cannot eliminate every risk. Crypto markets carry risks from price volatility, cyberattacks and operational failures, and security breaches at exchanges can expose customer assets even when platforms have protective measures in place.

The Hong Kong Monetary Authority (HKMA) reinforced this position in its comments on digital asset providers. It said licensed digital payment token companies must establish strict controls for technological and cybersecurity risks. The HKMA also regularly issues technology risk guidance and cyber threat alerts to regulated financial institutions, updates designed to help providers identify emerging attacks and strengthen their security measures.

Taken together, the statements from the two regulators highlight an important distinction: licensing establishes regulatory oversight, but it does not make crypto platforms immune to security failures.

For investors, the latest MAS warning underscores the need to assess exchange risks before depositing funds, with regulatory status, asset custody arrangements and security practices all warranting attention. The central message is clear: regulatory oversight can reduce certain risks, but it cannot guarantee the safety of cryptocurrency investments. Singapore's warning also places renewed focus on the responsibility investors themselves carry when choosing digital asset platforms.
