UPDATE 1-Turkish industrial output slides 4% in April on renewed lira weakness

(Adds analyst comment, details, background)

ISTANBUL, June 18 (Reuters) - Turkish industrial production fell a greater-than-expected 4.0% year-on-year in April, the Turkish Statistical Institute said on Tuesday, reflecting the impact of renewed lira weakness as the index declined for an eighth consecutive month.

Industrial production, regarded as a signal of growth data, declined in the wake of last year’s currency crisis, which caused the economy to contract annually in the last two quarters.

In a Reuters poll, the calendar-adjusted industrial output figure was forecast to fall 2.5% year-on-year. Month-on-month, industrial production was down 1.0% in April on a calendar and seasonally adjusted basis, the institute said.

Despite some signs of recovery in previous months, industrial output was hit by another bout of lira weakness in late March and April.

The currency has lost nearly 10 percent of its value this year, extending a 30 percent slide in 2018, fuelled mainly by Ankara’s strained ties with Washington as well as uncertainty over the outcome of Istanbul mayoral election.

The lira was slightly firmer on Tuesday, trading at 5.8690 by 0807 GMT against the dollar.

Confidence indices and the Purchasing Managers’ Index (PMI) data for March and April had signalled that the increased volatility in markets would be reflected on the real economy, said Muammer Komurcuoglu, research director at Is Investment.

“The industrial production data announced today shows the negative impact is being felt beginning in April,” he said, adding that the negative outlook is expected to continue in May.

“This situation points to the continuation of the contraction of growth in the second quarter,” he said.

Turkish manufacturing activity contracted in May, shrinking for the 14th month in a row due to slowing purchasing activity and moderation in new orders, a business survey showed earlier this month. Manufacturing PMI stood at 45.3, indicating contraction.

Economic confidence tumbled 8.5% in May, while consumer confidence dropped to its lowest level on record.
