This month marks the 10th anniversary of Lehman Brothers’ bankruptcy, a collapse synonymous with the 2008 financial crisis. The U.S. emerged from the Great Recession in 2009, entering what may be one of the country’s longest periods of economic expansion. But if all good things must end, it’s natural to wonder when to expect the next downturn and how to prepare. There’s chatter that a recession is on the horizon, and while no one knows exactly when, some economists think the U.S. economy could enter a downturn in 2020. The Federal Reserve also signals that gross domestic product — the value of all goods and services produced across the economy — will slump in 2020. Echoing fellow economists, Tendayi Kapfidze, chief economist at LendingTree, MagnifyMoney’s parent company, said he expected the economy to slow the second half of 2019.
