The Federal Home Loan Bank of Des Moines exceeded regulatory requirements during a test of its ability to withstand a severe downturn in the economy, according to a release. The stress tests are part of the Dodd Frank Consumer Protection and Wall Street Reform Act that was passed in the wake of the recession that ended in 2009. The current test was based on the Federal Home Loan Bank of Des Moines’ ability to withstand an economic calamity lasting from the first quarter of 2017 through first quarter of 2019 in which residential real estate prices dropped 25 percent, commercial real estate prices fell 35 percent, unemployment reached a peak of 10 percent and growth in gross domestic product ranged upward to 0.2 percent from negative 5.8 percent, among other drags on the economy. The Federal Home Loan Bank of Des Moines said its regulatory capital ratio — permanent capital divided by total assets — as of March 31, 2019, would stand at 5.68 percent, above the minimum requirement of 4 percent. The bank’s leverage capital ratio at that date would be 8.52 percent, above the minimum of 5 percent, with regulatory capital dropping over the test period to $4.6 billion from $8.1 billion.
