Taiwan Sept exports -5.3% y/y vs +1.5% Reuters poll
Exports to China -13.3% y/y (previous month -9.9%)
TSMC reports Sept sales jump 36.4% y/y
Finance ministry expects Oct exports -3% to -6% y/y
Ministry warns of "deepening doubts" about world economy
TAIPEI, Oct 7 (Reuters) - Taiwan's exports fell in September for the first time in more than two years on weakness in demand in major market China and stagnant consumer spending even as chip demand held up, with the government predicting more turbulence ahead.
Exports fell 5.3% in September from a year earlier to $37.53 billion, the Ministry of Finance said on Friday, logging a contraction for the first time since June 2020.
That was compared to the 2% rise recorded in August, and well below a forecast for a 1.5% increase in a Reuters poll.
Ministry official Beatrice Tsai said exports were coming off a high base last year, when the COVID-19 pandemic boosted demand for work-from-home gear like tablets, but the "root case" was the effect of high inflation, monetary policy tightening, and stagnant consumer demand from the cooling of China's economy.
Exports to China, Taiwan's largest trading partner, fell an annual 13.3% to $15.17 billion in September, after a 9.9% contraction in August, in a sign of the continued economic problems there.
China will not release its trade data until Oct. 14, after the end of the weeklong National Day holiday which began on Oct. 1.
However, Taiwan's overall exports of electronics components in September rose 2.4% to $16.99 billion, with semiconductor exports up 3.5% from a year earlier.
Many companies expect global chip shortages to last at least for the rest of the year, which will continue to bolster Taiwanese semiconductor firms' order books even as demand for some consumer electronics weakens.
Firms such as TSMC, the world's largest contract chipmaker, are major suppliers to Apple Inc and other global tech giants, as well as providers of chips for auto companies and lower-end consumer goods.
Earlier on Friday, TSMC reported September sales leapt an on-year 36.4%, though slipped 4.5% compared to August, while on Thursday smaller competitor United Microelectronics Corp said sales last month rose 34.5% year-on-year.
The finance ministry warned of trouble ahead from monetary policy tightening in the United States and Europe with manufacturing in various countries slowing significantly, saying there were "deepening doubts" about the outlook.
These problems may "highly impede our export performance in the fourth quarter", it added.
September exports to the United States were down 2.1%, compared with the 2.3% rise recorded the previous month.
Taiwan's September imports fell 2.4% to $32.51 billion, worse than economists' expectations of a 7% rise and after an expansion of 3.5% in August.
Taiwan could see October exports contract in a range of 3% to 6% from a year earlier, the finance ministry said. (Reporting by Liang-sa Loh and Ben Blanchard; Editing by Simon Cameron-Moore)
