U.S. Attorney General Eric Holder is planning to bring more mortgage fraud cases against banks in 2014, according to Reuters. The cases would follow a similar method that led to the massive $13 million settlement with JPMorgan last month.

While he would not state specifics, such as how many cases were planned or even the companies investigated, Holder did tell the news agency, ""We have a number of investigations that are coming to a head at the same time. It is my hope that the next round of these cases will be filed soon after the new year."

Spokespeople for some of the biggest banks, including Bank of America, Citigroup, Goldman Sachs and Credit Suisse, did not give any indication of how far investigations had proceeded other than the boilerplate response that they continue to cooperate with government authorities.
