The Monetary Authority of Singapore "may impose fines and sanctions against ANZ" as well as its Malaysian associate AMBank, according to a blog post by independent Malaysian journalist Ganesh Sahathevan over the weekend.Speculation that financial regulators in the UK, US and Singapore, UK and US could impose fines and other sanctions against Malaysia's AmBank, "as a means of punishing Malaysia's leadership" in connection with the consequences of the 1MDB scandal have circulated for some time.Sahathevan (a past contributor to Banking Day) wrote that he was "now aware that this option is being seriously considered, and [by] Singapore's MAS in particular." State sponsored financier 1Malaysia Development Berhad has, since 2015, featured in a local and ongoing political scandal enveloping Malaysia's prime minister, Najib Tun Razak. Exposés by The Sarawak Report, The Sunday Times and The Wall Street Journal cast the spotlight on alleged financial irregularities around key 1MDB accounts and a corresponding flow of funds into accounts under Najib's name at AmBank and one other bank.Financial regulators in Singapore have been among those to take the most decisive action in connection with financiers with connections to the 1MDB affair. In May, the Monetary Authority of Singapore ordered Swiss private bank BSI, which acted as banker to 1MDB and related parties, to shut its local branch.At the same time, Switzerland's Financial Market Supervisory Authority FINMA declared that BSI was "in breach of money laundering regulations".
