NEW YORK (MarketWatch) -- The U.S. stock market is paying more attention than usual to the movements of the U.S. dollar, with the greenback's newfound status as a funding currency leaving its moves highly correlated to equities and other riskier assets.
The greenback's status as both the world's reserve and funding currency means the Federal Reserve "still has the luxury of imposing its monetary policy on the global markets," said Dean Curnutt, president of Macro Risk Advisors LLC.
In essence, as Curnutt sees it, the central bank is managing "the most giant carry trade of all time," which has U.S. equities rising as the dollar weakens.
"These days, it all goes back to the dollar. The investment community tends to focus on something from time to time, right now it's the dollar," said Yu-Dee Chang, principal at ACE Investment Strategists LLC.
