TRADE WORRIES: With finance ministers and central bankers from the Group of 20 leading industrial and developing nations meeting in Buenos Aires Monday and Tuesday, there is mounting concern that a global trade war may be looming following the decision of U.S. President Donald Trump to slap tariffs on imported steel and aluminum. The European Union, for example, has already published a list of American products it plans to tax if it is not exempted from the tariffs announced by Trump. They are worth around 2.8 billion euros ($3.4 billion) in trade annually, but the list could grow to the equivalent of 6.4 billion euros once the full extent of the impact of U.S. tariffs is known.
ANALYST TAKE: "It's been a rocky start to trading at the start of the week, as the prospect of a trade war becomes ever more real," said Craig Erlam, senior market analyst at OANDA. "Despite what he says, I'm not sure that a trade war is what Trump actually wants from these tariffs or that he'll find much support for one within his party."
FED WATCH: Investors will also be closely monitoring this week's first meeting of the U.S. Federal Reserve's rate-setting committee under newly appointed Fed chairman Jerome Powell. Another quarter-point increase in the Fed's benchmark rate is anticipated. More important for investors is what the Fed says about the U.S. economic outlook and in particular its forecasts for inflation. "Jay Powell's first meeting as chairman will end with a rate hike, but the accompanying statement's tone and forecast update will be key for markets," said James Knightley, chief international economist at ING.
CHINA'S NEW FACES: A U.S.-trained economist was named to succeed longtime Chinese central bank governor Zhou Xiaochuan as part of a slate of new economic officials. The appointments come as Beijing tries to rein in surging debt and reduce financial risk. The new governor of the People's Bank of China, Yi Gang, is a 20-year veteran of the bank and known to foreign investors and regulators as head of China's foreign exchange regulator.
