In the 100th anniversary of it release, industrial production rose a greater-than-expected 0.3% (3.9% year-on-year) during December following a downwardly revised 0.4% gain in November (was 0.6%). October's output was revised up to +0.2% from -0.2%. The Action Economics Survey forecast 0.2% growth in December. During the last 100 years, U.S. industrial production has risen 2,094% or an annualized 3.1%.

Manufacturing activity jumped 1.1% (3.3% y/y) during December, with November's reading revised a touch higher. Utilities output fell 6.3% (-4.3% y/y), as a result of unseasonably warm weather in December. US Population-Weighted Heating Days were substantially below normal (89 days). Meanwhile mining activity fired up 1.5% (13.4% y/y).

Manufacturing production was bolstered by both durable goods (1.3%; 5.3% y/y) and nondurables (0.9%; 1.6% y/y). Motor vehicle output accelerated 4.7% (7.8% y/y) and aerospace and computers were up 1.7% (6.2% y/y) and 1.3% (6.5% y/y) respectively. These gains more than offset the 0.6% decline in machinery (+4.9% y/y). In the nondurable sector, chemical production rose 0.5% (3.6% y/y), food grew 0.9% (1.1% y/y), and petroleum & coal sizzled 3.5% (0.7% y/y).

By market group, consumer goods output was unchanged in December (1.0% y/y). Business equipment continued its healthy trend, up 0.5% (5.0% y/y). Construction supplies nailed 1.6% (2.1% y/y) growth. Materials gained 0.5% (6.1% y/y), though energy materials production edged down 0.1 (+9.5% y/y).

In the special aggregate groupings, production of high technology products sparked 1.0% (5.6% y/y). This was the result of strong gains in semiconductor & electronic components (1.5%; 7.5% y/y) and computer & office equipment (0.8%; 1.5 y/y). Factory sector production excluding the motor vehicle and high tech sectors rose 0.7% (2.6% y/y).

Capacity utilization increased to 78.7% in December, above the 78.5% expectations from Action Economics Survey. Factory sector use rebounded to 76.5% close to the business cycle high of 76.6% seen in November 2014. Mining jumped to a cycle high of 94.8%. Growth in capacity in the manufacturing sector continues to accelerate, up a cyclical high 1.4% y/y in December.

Industrial production and capacity data and US Population-Weighted Heating and Cooling Days are included in Haver's USECON database. Additional detail on production and capacity can be found in the IP database. The expectations figures come from the AS1REPNA database.
