The US economy contracted at a much steeper pace than previously estimated in the first quarter to record its worst performance in five years, but there are indications that growth has since rebounded strongly.

The Commerce Department said on Wednesday gross domestic product fell at a 2.9 per cent annual rate, instead of the 1.0 per cent pace it had reported last month.

While the economy’s woes have been largely blamed on an unusually cold winter, the magnitude of the revision suggests other factors at play beyond the weather.

Growth has now been lowered by a total of 3.0 percentage points since the government’s first estimate was published in April, which had the economy expanding at a 0.1 per cent rate.

The difference between the second and third estimates was the largest on records going back to 1976. Revisions to GDP numbers are not unusual as the government does not have complete data when it makes its initial and preliminary estimates.

Economists had expected growth to be revised to show it contracting at a 1.7 per cent rate.

US stock index futures fell on the data, while prices for US government debt rose. The dollar fell against a basket of currencies.

The latest revisions reflect a weaker pace of healthcare spending than previously assumed, which caused a downgrading of the consumer spending estimate. Trade was also a bigger drag on the economy than previously thought.

The economy grew at a 2.6 per cent pace in the final three months of 2013. Data on employment, manufacturing and services sectors point to a sharp acceleration in growth early in the second quarter.

However, the pace of expansion could fall short of expectations, which range as high as a 3.6 per cent rate.

In a second report, the department said orders for long-lasting US manufactured goods fell 1.0 per cent last month.

Orders for these items, which range from toasters to aircraft that are meant to last three years or more, fell for the first time in three months.

They were dragged down by weak demand for transportation, machinery, computers and electronic products; electrical equipment, appliances and components; as well as a 31.4 per cent plunge in defense capital goods orders.

Economists estimate severe weather could have slashed as much as 1.5 percentage points from GDP growth in the first quarter. The government, however, gave no details on the impact of the weather.
