Aug 27 (Reuters) - G20 policymakers meeting in London next week will likely pledge to maintain accommodative policies for as long as is needed, a G7 source told Reuters on Thursday.
The source, who did not want to be identified, said language contained in the G20 leaders' communique in April on economic stimulus was not likely to change in any substantive way when finance ministers and central bankers make a new statement on Sept 5.
In April, the G20 said: "Central banks have pledged to maintain expansionary policies for as long as needed and to use the full range of monetary policy instruments including unconventional instruments, consistent with price stability."
Similarly, the G20 would stick to its existing formulation on exit strategies, trying to assure markets that credible plans were in place but not indicating any imminent move to tighten.
"Anything else would make people think something was about to happen," the source said.
