The U.S. Conference Board said Monday its index of leading economic indicators declined by 0.2% in March to 110.6, pushed down by worries over oil prices, the war and potential terrorism. The result was in line with analyst expectations.

Although the index was down for a second consecutive month after a 0.5% drop in February, the Conference Board said information available so far in April suggests the declines will not continue.

Still, it warned of a threat from consumers’ lower expectations, raising “the spectre of a fall-off in consumption growth.”

“This is significant because without much investment or export growth, only consumption has been fuelling the economy,” said Conference Board economist Ken Goldstein.

The index of leading economic indicators is intended to measure where the overall U.S. economy is headed in the next three to six months.
