What’s next for Charles E. Haldeman, who resigned yesterday as chief of the Boston-based fund company Putnam Investments? According to today’s Wall Street Journal, he may be in line to be named the next chief executive officer of Freddie Mac.

Haldeman, 60, resigned yesterday as chairman of Putnam Investment Management, president of the Putnam Funds and member of the Board of Trustees of the funds.

Citing “people familiar with the situation,” the Journal reported that Haldeman is a prime candidate for the CEO position at the government-backed mortgage provider Freddie Mac, because “he is believed to have improved morale, regulatory compliance and financial controls at Putnam Investments.” Like its sister agency, Fannie Mae, Freddie Mac is under conservatorship, so he would have to be approved for the role by the Federal Housing Finance Agency and the U.S. Treasury.

Putnam Investments did not return a call seeking comment. A spokeswoman for Freddie Mac said the agency could not comment about the report, because the CEO nomination process is not complete.
