Overview: A world with higher inflation Our world GDP growth forecasts are unchanged this month, at 2.6% for 2017 and 2.9% in 2018. But we expect a sizeable increase in inflation, to 3.3% in 2017 from an estimated 2.8% in 2016, as the effect of higher oil prices feeds through., Global indicators continue to point to a pick-up in activity towards the end of last year, driven by stronger manufacturing activity. The global manufacturing PMI rose to the highest level in almost three years in December, while the composite index - which includes services - was at a 13-month high., World trade should be underpinned by stronger growth in the US (2.3% in 2017 and 2.5% in 2018), bolstered by the anticipated effects of President Trump's expansive fiscal policies. That said, uncertainties around our central forecast are unusually high given the high level of uncertainty surrounding the Trump administration. Encouragingly, there are increasing signs that the tighter labour market is leading to a pick-up in wage inflation in the US, which will support consumers., Given these reflationary trends, we expect two increases in the Federal funds rate this year and US bond yields are likely to continue to rise. The widening of interest rate differentials between the US and the Eurozone will drive the euro down to parity with the US dollar by end-2017 for the first time since 2002., We have revised our Brexit assumptions this month. We now assume that the two-year period of exit negotiations is followed by a transitional arrangement lasting 2-3 years. This would provide breathing space to negotiate a free trade agreement with the EU., Emerging market growth on the whole will improve in 2017 but performance will differ across countries: Russia and Brazil will exit recession, but countries with weak balance of payments positions, high dollar debt and exposure to possible US protectionist actions will be at risk. In China, policymakers are moving to greater emphasis on reducing financial risks and less focus on the 6.5% GDP growth target for 2017. Continued action is also likely to dampen further depreciation of the CNY. [ABSTRACT FROM AUTHOR]
