South Korea's factory activity contracts for 13 straight months

South Korea's factory activity contracted for a 13th straight month, according to private surveys from S&P Global.

The manufacturing purchasing managers index came in at 49.4 in July, which is its softest contraction in a year.

S&P Global wrote that this was due to a slower reduction in output levels in July, in part due to a renewed expansion in exports.

This is also in addition to positive indications for demand conditions in July, which led manufacturers to increase staffing levels for the third month in a row. Input costs also fell for the first time in just over three years and at the fastest pace since July 2017.
