Key updates
Japan factory output falls as US tariffs bite
Japan’s factory output dropped 1.1% in March, exceeding forecasts, as Trump’s steep US tariffs disrupted motor vehicle exports and supply chains. Auto production slumped 5.9%, with small vehicle output plunging over 23%. As Japan braces for further negotiations, concerns grow over a broader global slowdown. Komatsu expects a $650 million profit hit from the tariffs and a strong JPY.
China factory activity slumps amid tariff shock
China’s factory activity fell to a 16-month low in April, with the PMI dropping to 49 as US tariffs under Trump’s “Liberation Day” package hit exports. Weak domestic demand and global uncertainty intensify pressure on Beijing to boost stimulus. Analysts expect further fiscal and monetary measures, as China navigates deflation and waning external demand.
Oil prices down d-o-d
Oil prices dipped as investor sentiment turned bearish amid escalating trade tensions and weak economic signals. China’s factory slowdown and falling US consumer confidence added to recession fears. Market participants remain cautious ahead of the OPEC+ meeting, with concerns that earlier economic strength was driven by temporary pre-tariff stockpiling.
