The current head of the financial stability unit is to take on his new role with the auditing firm in April 2011.
Mr Strachan, who has worked with the FSA for 12 years and the Bank of England (BoE) for 13, was also playing a key role in the administering the changes to the infrastructure of the regulatory body.
His experience extends to representing the UK and the FSA on the Basel Committee as well as working on the Turner report.
The executive is to join Deloitte in the capacity of co-head of their Centre for Regulatory Strategy.
Clifford Smout, co-head of the body, said Mr Strachan would bring a wealth of experience to Deloitte.
âHe has worked at the forefront of UK regulation for a long period, for instance in his current role overseeing the formation of the future UK regulatory set-up," he said.
"Having worked with David at the BoE, I look forward to joining him again as we lead the Deloitte Centre for Regulatory Strategy.â
Meanwhile, recent research from recruitment consultant Astbury Marsden revealed that the implementation of new regulation by the FSA is leading to an increase in the amount of staff hired to work on compliance in the financial services industry.
