The author argues that a resumed US-China trade war would likely prompt Beijing to weaken the renminbi, as it did in the past 18 months. The PBoC's daily fixing sets the midpoint of a band around spot, and the central bank intervenes when spot reaches either edge of the band.
A deliberately weaker renminbi would make Chinese exports more competitive and raise the cost of dollar-priced commodity imports. That combination could reduce China's demand for US farm goods while supporting its export sectors.
