Core private-sector machinery orders increased a seasonally adjusted 10.8 pct in April from March, the Cabinet Office said, far better than market estimates. The market was looking for a rise of 3.7 pct based on a poll by the Nihon Keizai Shimbun. Core private-sector machinery orders, which exclude volatile orders from electric utilities and for ships, are viewed as a leading indicator of corporate capital spending. Year-on-year, core machinery orders were up 12.2 pct in April.
