U.S. stocks rose the most in a week, while Treasuries declined and the dollar gained on growing speculation the Trump administration is gaining momentum in its efforts to reform the tax code. Industrial metals rallied.

The S&P 500 Index jumped 1 percent and the Dow Jones Industrial Average added almost 200 points amid reports the Trump team and lawmakers may be making progress toward pro-business reforms. Emerging-market and European equities also advanced. The risk-on tone lifted the dollar and weighed on havens from Treasuries to gold. Crude gained ahead of a U.S. government report that's forecast to show stockpiles fell.

Investors seem to be getting over some of the sensitivity that characterized the past week following political turmoil in Washington, terrorist attacks in Europe and ongoing tension between the U.S. and North Korea. Nonetheless, Ray Dalio, the billionaire founder of Bridgewater Associates Inc., the world's largest hedge fund, said he's "tactically reducing" risk because he's concerned about growing internal and external conflict "leading to impaired government efficiency" in the U.S., according to a LinkedIn post Monday.

With little top-tier economic data out this week, markets are set to focus on the annual conference of global central bankers hosted by the Kansas City Federal Reserve Bank in Jackson Hole, Wyoming. It starts on Thursday.

"No one has a lot of interest in being very negative in the market right here, knowing that there's this whatever-it-takes backdrop where central bankers globally just have zero interest in seeing financial conditions tighten too much," Dennis DeBusschere, head of portfolio strategy at Evercore ISI, said Tuesday in an interview on Bloomberg Television.
