Japanese manufacturers' confidence index turned negative to the central bank's forecast in December. A short-term survey in Reuters, Japan, found that Japanese manufacturers' business confidence deteriorated further in December due to concerns about US protectionist policies. The survey of 505 large Japanese non-financial enterprises showed that manufacturers' confidence index fell from 5 in November to -1 in December, which was the first time since last February, and the number of pessimists exceeded optimists for the first time in 10 months. The loss of business confidence may cast a shadow over the Bank of Japan's forecast. The Bank of Japan had previously predicted that a steady recovery driven by rising wages and consumption would help inflation reach the 2% target in a sustainable way and justify further interest rate hikes. Many manufacturing industries have reported that business confidence has declined. Among electronic machinery manufacturers, steel and non-ferrous metal manufacturers, pessimists far exceed optimists.Navigation warning!
