Manufacturing business monitor signals a downturnBy Crystal Hsu / Staff reporterThe business climate monitor for the manufacturing industry turned “blue” in March, from a revised “yellow-blue” in February, as demand, selling prices and operating conditions weakened, the Taiwan Institute of Economic Research (TIER, 台灣經濟研究院) said yesterday. The business composite index compiled by the Taipei-based think tank shed 0.56 points to 10.41, reflecting listless manufacturing activity, as global clients continued to adjust inventory amid poor sales. TIER uses a five-color spectrum to capture the industry’s movements, with “red” indicating a boom, “green” suggesting steady growth and “blue” signifying a downturn. Plastic and rubber product makers saw business shrinking by a similar amount, despite the peak season starting, the institute said. Vehicle sales picked up after chip shortages came to an end, enabling local suppliers of auto parts to report steady business growth, it said.
