According to authorities in Singapore, a city-state with one of the world's lowest crime rates, David Roach strolled into a Standard Chartered bank branch last July, handed the teller a scrap of paper and walked off with the cash.
The 28-year-old then fled to Bangkok where he was arrested a few days later in a hostel.
On Tuesday a Thai criminal court convicted Roach of violating money laundering and customs laws by bringing the loot into the country.
"The suspect confessed to all charges during the investigation process," the judge said.
Bank robberies are extremely rare in Singapore, whose zero-tolerance stance to crime has made it one of Asia's safest cities.
Singapore and Thailand do not have an extradition treaty but share close diplomatic ties.
