Justin Yek is taking over as Binance’s chief financial officer. He replaces Kaiser Ng, who is leaving the cryptocurrency exchange to pursue a new venture.
Yek previously worked at fintech company Airwallex and investment bank Morgan Stanley, where he held senior finance and banking roles.
Binance announced the change on November 7. The news came just days after the exchange disclosed a security breach involving approximately $6.3 billion in cryptocurrency. The timing attracted attention, but Binance said the CFO transition had been in the works for about six months.
Co-CEO Yi He said Ng had decided to pursue a new venture after more than five years at the exchange.
Who is Binance’s new CFO Justin Yek?
Yek is a finance executive and software engineer based in Singapore. At Airwallex, he served as vice president of finance. The fintech provides payment services for businesses operating across borders.
He later joined Morgan Stanley, where he led the technology investment banking business in Southeast Asia. His work involved advising companies on investments, deals and plans to go public.
Earlier, from 2009 to 2014, he worked for Citigroup in Hong Kong. He then co-founded Altitude Labs, a company that develops software for web and mobile platforms. The company was later sold.
He studied financial engineering at Columbia University and holds an ACCA qualification. His background also includes software development and fintech, alongside his work in banking and finance.
Yek joined Binance in May 2026, so he is already familiar with the company’s finance operations. In a LinkedIn post, he thanked Ng for helping with the handover and said he was ready to take on the CFO role.
CFO change comes after a major security breach
Ng had served as Binance’s CFO since 2022. Before joining the exchange, he held the same position at Kraken.
His departure comes shortly after the October 29 security incident, in which approximately $6.3 billion in cryptocurrency was affected. Binance said the attack involved malware hidden in software downloads and fake recruitment efforts targeting engineers. Several employees’ computers were compromised.
Binance has said it will cover the losses suffered by affected customers. The FBI has linked the attack to TraderTraitor, a hacking group associated with North Korea.
The exchange says Ng’s departure and Yek’s appointment are part of a transition planned months before the security incident.
