The Obama administration looks poised to adopt a private-public partnership model for dealing with toxic assets as part of the financial rescue plan to be announced on Tuesday by Tim Geithner, Treasury secretary.

The approach will build on the experience of other nations in using government-run “bad banks” to clean up after banking crises but do so in a way that leverages private capital and expertise. US officials hope to use a combination of guarantees and government financing to “crowd” in the private sector.
