Jens Sturzenegger, a former branch manager at Falcon Private Bank in Singapore, became the first foreigner convicted in the city's probes linked to a Malaysian state investment fund.
Sturzenegger, 42, pleaded guilty to six charges, including failing to report suspicious transactions, and was sentenced to 28 weeks in jail and fined S$128,000 ($89,000). Prosecutors had sought a jail term of as long as 32 weeks.
His lawyer Tan Hee Joek said in court that Sturzenegger is remorseful and didn't gain financially from the offences. Tan said after the hearing his client won't appeal the sentence.
The Swiss had been charged with 16 counts, including not reporting to the authorities that $1.27 billion of inflows into two bank accounts were suspicious and denying knowing Malaysian financier Low Taek Jho.
