The company said that opening a Sydney office is in response to the regulatory reforms being implemented in the $600 trillion global OTC derivatives market, particularly with the introduction of the Dodd Frank Act in the US and the European Union's European Market Infrastructure Regulation, both of which are expected to have a global impact.

GreySpark was founded in London in 2009 and advises investment banks, hedge funds and asset management firms. It has over 70 consultants worldwide. Sydney is its third office in the Asia-Pacific region, the first being Hong Kong in 2011 and then Singapore in 2012.
