Gauge of future health of US economy jumps 0.7 per cent in May, second strong monthly gain

WASHINGTON - An index designed to predict the future health of the economy posted a second straight strong increase in May, indicating the economy should gain strength in the second half of this year.

The Conference Board said Thursday that its index of leading indicators rose 0.7 per cent in May, matching the gain in April. Both months represented the strongest increase since a 1 per cent rise last July.

Ataman Ozyildirim, director of business cycle research for the Conference Board, said the recent strength was "confirming the outlook for more economic expansion in the second half of the year after what looks to be a much weaker first half."

The economy actually shrank in the first three months with the gross domestic product contracting at an annual rate of 0.7 per cent.

But economists say growth rebounded to around 2 per cent in the current April-June quarter and will strengthen even further to around 3 per cent in the second half of the year.

The index of leading indicators is composed of 10 forward-pointing indicators. Nine of the 10 showed strength in May led by a big surge in applications for building permits. One indicator, average weekly hours worked in manufacturing, was unchanged in May.
