For the 19th time in the past 20 months, Creighton University’s Rural Mainstreet Index sank below the 50.0 growth reading in April, according to the monthly survey of bank CEOs in rural areas of a 10-state region dependent on agriculture and energy. The region’s overall reading for April fell to 40.0 from March’s 41.1. The survey also revealed that three-fourths of rural bankers support President Trump’s increase in tariffs on imports from China.
