A former Royal Bank of Canada banking associate has been sentenced to 23 months in jail by the Sydney District Court after pleading guilty to revealing insider information.

John Kay Jin Khoo was sentenced to a minimum of 14 months in prison after pleading guilty to four charges of communicating inside information. Khoo was found to have divulged sensitive information to Jia Yao Matthew Tan of Waterloo, Sydney, who was sentenced in April 2013, and another person, while working at RBC in 2010 to mid-2011.

"Insider trading will not be tolerated. Regardless of whether it is buying and selling, communicating information, or any other form, ASIC has the people, the power and the systems in place to catch the individuals involved," said Cathie Armour, ASIC commissioner.

Khoo is to be released in his own recognisance in the sum of A$500 ($454) to be of good behaviour for the remaining nine months. 

Since 2009, the Australian Securities and Investments Commission has prosecuted 29 insider trading matters.
