World Economic Prospects.

Overview: Dollar surge brings mixed consequences The strengthening dollar is now becoming a significant factor for global growth and our forecasts. The tradeweighted dollar is up 2.5% over the last month and over 12% on a year ago., Driving the latest rise are growing expectations of US rate hikes while monetary policy in many other major economies is headed in the opposite direction., The beginning of ECB QE has prompted a further slide in bond yields and the euro - which at 1.06/US$ is on course to fulfill our forecast of near-parity by year-end. Weak data in Japan also raises the chance of a further expansion of QE there later this year., We remain relatively positive about the advanced economies: we forecast G7 GDP growth at 2.2% for 2015 and 2.3% next. This month we have revised up German growth for 2015 to 2.4% - a four-year high., Robust US growth and a strong dollar are good news for the advanced economies. US import volume growth firmed to over 5% on the year in January, while the dollar surge potentially boosts the share of other advanced countries in this growing market., But for the emerging economies the picture is mixed. A stronger US may boost exports, but rising US rates are pulling capital away: there has been a slump in portfolio inflows into emergers in recent months. Emerging growth may also suffer from higher costs of dollar funding and a rising burden of dollar debt as currencies soften - the more so if US rates rise faster than markets expect., Moreover, emergers are also under pressure from a slowing China. Chinese import growth has been weak of late and commodity prices remain under downward pressure. A notable casualty has been Brazil, which we have downgraded again this month - GDP is expected to slump 1.1% this year., Emerging GDP growth overall is expected to slip to 3.7% this year, the lowest since 2009. And excluding China, emerging growth will be only 2.2% - the same as the G7 and the worst performance relative to the advanced economies since 1999. [ABSTRACT FROM AUTHOR]
