While creating the largest Federal Home Loan Bank in the system, both geographically and membership wise, about 75 percent of the Federal Home Loan Bank of Seattle workforce will be laid off due to a merger with the Federal Home Loan Bank of Des Moines. The merger, approved in December by the Federal Housing Finance Agency, officially goes into effect in June, trimming the Seattle bank’s workforce to just 35 employees in the regional office. About 109 employees will be laid off before 2015 ends. Both banks unanimously approved the merger and said it will result in a cooperative that is stronger than either bank on an individual basis. Once combined, the bank will be headquartered in Des Moines.
