Singapore on Monday predicted sharply lower economic growth of 1.0-3.0 percent in 2012 from an estimated 5.0 percent this year amid an export slowdown, and warned the situation could worsen. \"This does not factor in downside risks to growth, such as a worsening debt situation or a full-blown financial crisis in the advanced economies,\" the Ministry of Trade and Industry said in a statement. \"Should these risks materialise, growth in the Singapore economy in 2012 could come in lower than expected,\" it added.
