SINGAPORE - Singapore is poised to tighten monetary policy at a review next week, with the Middle East war driving up energy prices, stoking inflation and darkening the growth outlook at home and abroad.

Out of 13 analysts polled by Reuters, 11 expect the Monetary Authority of Singapore (MAS) to tighten policy on April 14. MAS left settings unchanged in January this year, as well as in July and October last year after easing in January and April.
