Manufacturers in New York appear to be responding by lowering labor costs. The average work week fell in December to its lowest level since early 2009, the New York Fed said.
Other recent manufacturing data has sent mixed signals. There are some signs that factory output has bottomed out, while other reports suggest manufacturers are still struggling. Either way, the strong dollar is likely to weigh on the sector for months.
That's partly because the Federal Reserve is expected to announce its first increase in short-term interest rates in nine years on Wednesday. Yet interest rates will likely remain low in Europe and Japan. Higher rates in the U.S., compared with other developed countries, will push up the dollar's value.
Still, U.S. factory production rose in October for the first time in three months, the U.S. Fed said last month, boosted by stronger output of cars and computers. The Fed will release updated data on the nation's manufacturing sector on Wednesday.
Yet a private survey of manufacturers released earlier this month found that factory activity shrank in November for the first time in three years. U.S. manufacturers said new orders fell that month compared with October, while production also declined.
