Treasury Secretary Timothy F. Geithner said he doesn’t expect President Barack Obama to ask him to stay in office if he’s re-elected, and he dismissed Wall Street’s concerns about financial regulations.

“He’s not going to ask me to stay on, I’m pretty confident,” Geithner said in an interview with Bloomberg Television today. “I’m confident he’ll be president. But I’m also confident he’s going to have the privilege of having another secretary of the Treasury.” He said he would do “something else.”
