Most major economies grow with great synchronicity several years after the global financial crisis. These economies experience high stock market valuation, healthy fundamental recalibration, job creation, high productivity, and artificial-intelligence automation. For instance, the U.S. economy operates near full employment with 1.5%-2% moderate inflation, $2.5 trillion mandatory government expenditures, and $1.5 trillion tax cuts. Also, Europe now feels the benign effects of easy money that arises from the European Central Bank's (ECB) quantitative-easing and negative-interest-rate monetary policies. Asian economies such as Hong Kong, Singapore, South Korea, and Taiwan experience economic revival due to the global upstream prosperity of Apple-and-Samsung-driven mobile device production.

Key recent oil price increases boost economic gains for Russia, Saudi Arabia, and other middle-east producers. Meanwhile, Brazil still suffers the ripple effects of a veritable depression and now flashes tentative signs of macroeconomic recovery with high population dividends.

However, several other economies exhibit weak macro momentum with chaotic bouts of economic policy uncertainty. England now has to confront high unstable exchange rates, wide stock market gyrations, and trade barriers in the post-Brexit investment horizon. China may land hard with sub-6% real GDP economic growth due to the potential Sino-American trade war. Mexico may fail to transcend fears and doubts that the Trump team menaces its recent economic convalescence with hefty tariffs and border taxes.

The International Monetary Fund (IMF) predicts 2.7%-3% U.S. real GDP economic growth and 3.7%-3.9% economic growth worldwide. IMF research now warns of economic inequality, cybersecurity, extreme weather, and political confrontations such as U.S.-Korean nuclear threats and fair trade barriers.
