The Monetary Authority of Singapore (MAS) published its summary of key enforcement actions taken in the second quarter of 2026 on 1 July, setting out a series of financial penalties, a custodial sentence and the revocation of a Major Payment Institution Licence. The round-up covers matters concluded between April and June and is intended, in the regulator's words, to demonstrate the range of misconduct addressed under its supervisory perimeter across fund management, capital markets and payments.
The publication brings together enforcement measures spanning the full breadth of the licensed community and reinforces the MAS message that both firms and individuals face consequences where breaches of the Securities and Futures Act and other rules are established. Each of the actions summarised had been announced individually before being collated in the quarterly release, offering the market a consolidated view of the authority's supervisory posture.
COMPOSITION FINES AND LICENCE ACTION
Among the headline items, Havenport Investments was issued with a composition fine of S$40,000 on 18 May 2026, alongside a reprimand of its senior management. The MAS statement grouped the firm-level penalty with the reprimand to underline supervisory expectations of accountability at the top of licensed institutions, a recurring theme in the authority's public enforcement work.
Two days later, on 20 May, the authority revoked the Major Payment Institution Licence held by Bsquared Technology Pte Ltd. The revocation removes the firm's ability to carry on regulated payment services in Singapore and stands as the most significant firm-level sanction disclosed in the quarter. Losing an MPI licence is a defining regulatory event for any payments operator, as it terminates the legal basis on which the firm can offer services such as domestic money transfer, cross-border transfer, merchant acquisition, e-money issuance and digital payment token services in the jurisdiction.
The MAS said the enforcement summary is part of its ongoing programme to publish enforcement outcomes so that market participants can better understand the standards required under Singapore's financial services legislation. Publication in a quarterly format is designed to reinforce transparency while providing regulated firms with practical guidance on the kinds of conduct that draw supervisory attention.
INDIVIDUAL PENALTIES AND CUSTODIAL SENTENCE
On the individual side, Xie Jianfeng was fined S$200,000 on 20 May 2026 for trading offences under the Securities and Futures Act. The penalty reflects the regulator's continued focus on market misconduct and false trading, which MAS has repeatedly identified as a priority area for enforcement in its capital-markets supervision programme.
Related conduct also produced a custodial outcome. Tan Chun Yong received a ten-week imprisonment sentence handed down on 19 to 20 May 2026 for connected trading offences, the summary said. The prison term underscores that criminal liability, and not only administrative sanctions, remains available where the courts find the evidence supports prosecution, and it demonstrates the willingness of Singapore's authorities to seek custodial outcomes for capital-markets abuse.
Taken together, the five actions highlighted in the summary illustrate the mix of tools MAS deploys across composition penalties, licence revocations, financial penalties on individuals and criminal referrals. The authority reiterated in the press release that further updates on its enforcement work will be published on its website in line with its usual half-yearly and quarterly disclosure practice, with the Q2 2026 round-up now available alongside earlier statements on the enforcement actions page.
