South Korean Business Manufacturing Survey (Sep) 99.5 (Prev. 103.8)

A move from above to below the 100 neutral line carries more weight than the size of the drop alone, since the level signals whether the manufacturing cohort is in expansionary or contractionary mood rather than merely its degree. The established pattern is that a single soft survey moves the won and Kospi only modestly; sustained repricing comes when the survey direction is confirmed by the hard trade data, which Korea releases earlier than most peers. The distinction worth drawing is between domestic-demand softness and export-order weakness, since the sub-indices separate the two and only the latter transmits cleanly to regional peers and global chip-cycle proxies. The follow-ons are the monthly trade figures, the export-heavy components of subsequent surveys, and whether the central bank's growth language shifts at its next meeting. As a survey rather than a hard print, the signal is directional and easily revised by the next month's reading.
