Confidence among U.S. consumers jumped in May by the most in six years, fueling speculation the economy will recover later this year.

The U.S. Consumer Confidence Index (CCI) is an indicator designed to measure consumer confidence, which is defined as the degree of optimism on the state of the economy that consumers are expressing through their activities of savings and spending. Global consumer confidence is not measured. Country by country analysis indicates huge variance around the globe. In an interconnected global economy, tracking international consumer confidence is a lead indicator of economic trends.

The Conference Board Consumer Confidence Index™, which had improved considerably in April, posted another large gain in May. The Index now stands at 54.9 (1985=100), up from 40.8 in April. The Present Situation Index increased to 28.9 from 25.5 last month. The Expectations Index rose to 72.3 from 51.0
