The International Monetary Fund on Monday boosted its estimates for US growth on expected stimulus spending by the incoming Trump administration, but kept the forecast for global growth unchanged. The IMF›s quarterly World Economic Outlook (WEO) however said the forecasts for 2017 and 2018 are beset by uncertainty and risk, including signs of rising protectionism. It sees world growth of 3.4 percent this year and 3.6 percent in 2018, unchanged from the October report, as concerns about slowing in major developing economies were offset by the recovery in advanced economies and China. The US growth estimate was raised a tenth of a point this year to 2.3 percent, and for next year by four-tenths to 2.5 percent. The IMF said it used the most likely of many possible scenarios for the United States under President-elect Donald Trump, one that includes higher spending and other steps to boost the economy. This is in contrast to the World Bank report released last week, which did not change the US forecasts because it said Trump›s policy plans were too uncertain. Both organizations agree the forecasts are clouded by unknowns. There is «a wide dispersion of possible outcomes around the projections, given uncertainty surrounding the policy stance of the incoming US administration and its global ramifications,» the IMF said. However, the forecasts should become more certain by the release of the next World Economic Outlook in April «as more clarity emerges on US policies and their implications for the global economy,» it said. Among the uncertainty to the outlook, the IMF noted that increased spending to stimulate the economy, as Trump has proposed, means «stronger future demand implying more inflationary pressure,» which in turn means the US central bank may have to raise interest rates faster than currently expected. The Federal Reserve increased the benchmark lending rate in December, and policymakers indicated they may need to implement three more increases this year but they too stress the uncertainty about policies to be implemented by the Republican Trump, who takes office Friday. Trump has repeatedly threatened to slap import tariffs on goods from Mexico and China, and to restrict immigration, part of a growing protectionist political sentiment in many countries. But the IMF warned that executing those policies could backfire on the US economy and create ripple effects abroad. Recent political developments highlight a fraying consensus about the benefits of cross-border economic integration, the IMF said, noting the anti-globalization sentiment could get worse if trade deficits expand further. But, it warned, increased restrictions on global trade and migration would hurt productivity and incomes, and take an immediate toll on market sentiment. If growth in the US and China increases more than expected as a result of the higher spending, that would have «positive spillovers to their trading partners, unless protectionist measures counteract that. While major developing economies like India, Brazil and Mexico are facing slowdowns, the IMF raised its estimate for China given increased government spending to boost growth. The IMF revised the 2017 China growth forecast to 6.5 percent, 0.3 point higher than in October, while the 2018 estimate is unchanged at 6.0 percent. However, the fund cautioned that the spending that is fueling growth in China will be difficult to sustain and raises the risk of a sharper slowdown or a disruptive adjustment. The IMF cut the 2017 forecast for India by 0.4 percentage points to 7.2 percent, while the 2018 forecast was unchanged at 7.7 percent. Mexico saw its growth estimate slashed six-tenths of a point in each year to 1.7 percent this year and 2.0 percent in 2018. For Brazil, the estimate was trimmed 0.3 point to just 0.2 percent this year, rising to 1.5 percent in 2018, unchanged from the October forecast. But advanced economies generally are doing better, with Japan›s economy seen expanding 0.8 percent this year, 0.2 point better than the last forecast, and 0.5 percent in 2018. The outlook for the euro area is picking up, with growth of 1.6 percent expected this year and next, an upward revision of 0.1 point in the 2017 forecast. This WEO forecast also incorporates a firming of oil prices «following the agreement among OPEC members and several other major producers to limit supply,» the IMF said. That will help commodity exporters, including Russia, although the growth estimates for Moscow were unchanged at 1.1 and 1.2 percent for 2017 and 2018, respectively.
