Bloomberg reports:

Treasury Secretary Timothy F. Geithner has signaled to White House officials that he’s considering leaving the administration after President Barack Obama reaches an agreement with Congress to raise the national debt limit, according to three people familiar with the matter.
Geithner hasn’t made a final decision and won’t do so until the debt ceiling issue has been resolved, according to one of the people. All spoke on condition of anonymity to discuss private discussions.
The Treasury secretary has said the U.S. risks defaulting on its obligations if Congress doesn’t raise the $14.3 trillion debt ceiling by Aug. 2. The administration and congressional Republicans are at an impasse in negotiations to raise the limit, which also is tied to efforts to cut the nation’s long- term deficit.

Geithner’s exit would round out the wholesale departure of Obama’s economic “brain trust,” with Austan Goolsbee, chairman of the Council of Economic Advisors, set to leave his post in early August.

UPDATE: According to The Hill, reports that Geithner will leave after a debt deal is completed could be premature.
