European markets are set for a busy day on Tuesday with preliminary growth numbers for the euro zone, inflation in Italy, jobless data for Britain, and the German economic sentiment ZEW survey all being released. Analysts predict no surprises in euro zone GDP data, but the German ZEW survey for May is expected to be in the spotlight. The weakness in the euro zone's largest economy is a concern for market bulls, especially given Asia's largest economy is still struggling to get demand going. The U.S. debt ceiling debate is also ongoing, with President Joe Biden and Republican House of Representatives Speaker Kevin McCarthy meeting on Tuesday to find common ground on spending levels and an increase in the nation's debt limit.
