World stocks clung to recent gains on December 30 following healthy advances in Asia on hopes for a U.S.-China trade deal, a more optimistic growth outlook and a softer dollar, while the euro climbed to a 4-1/2 month high.
Yet European stock markets failed to follow the lead and took a breather following last week's record highs.
The pan-regional Euro Stoxx 600 was down 0.3 percent while Germany's DAX slipped 0.5 percent. Banks , which had been lagging the 2019 rally, were the only sector to mark small gains in thin year-end trading.
"Investors appear to be growing a tad apprehensive about chasing the record setting U.S. equity market risk-reward premise into year-end," Stephen Innes at AxiTraderÂ wrote in a note to clients. "Much focus continues to fall on the abundance of liquidity offered up by the Fed as a critical driver behind the late-season equity market window dressing."
Many Asian bourses had marked healthy gains with Chinese blue chips roaring 1.5 percent higher, bolstered by a report that 2019 retail sales are forecast to rise 8 percent and expectations that a new benchmark for floating-rate loans could lower borrowing costs and boost flagging economic growth.
Yet Japan's Nikkei stock index finished its last trading day of the year down 0.76 percent. The index gained 18.2 percent in 2019 after dropping 12.8 percent last year.
Easing trade war worries have offered a lift to global equities this month, putting MSCI's global equity index on track for a 3.8 percent rise in December - its fourth straight month of gains.
U.S. futures also pointed to a higher open after the S&P 500 and the Dow Jones Industrial Average closed at records on Friday.
In currency markets, the dollar index - measuring the currency against a basket of rivals - weakened 0.1 percent to 96.793 in its third straight session in the red. Thin end-of-year volumes exacerbated the broad weakness in the greenback which on Friday suffered its biggest one-day fall since June.
"The U.S. dollar is the worst performing G10 currency overnight," said MUFG's Fritz Louw. "The main drivers of the weaker dollar have likely been risk appetite holding up in the wake of comments from the US pertaining to a Phase One trade deal recently as well as the US Federal Reserve's continued repo operations."
The weak greenback helped other currencies shine. The euro climbed as high as $1.1211, its strongest level since mid-August. Sterling also benefited, rising 0.2 percent to $1.3122 against the dollar. Yet the pound was flat against the euro at 85.38 pence amid concerns that Britain could be headed for a disruptive "hard Brexit" at the end of 2020.
China's yuan held below the key level of 7 per dollar, rising in offshore markets to 6.9752, its highest since December 13.
In fixed income markets, rising risk appetite saw euro zone bond yields rise across the board, with most 10-year bond yields two basis points higher on the day. Germany's Bund yield stood at -0.23 percent, heading back towards recent six-month highs.
The softer dollar also lifted commodity markets with gold hitting a two month peak.
Oil prices held near three-month highs with traders also keeping a close watch on the Middle East following U.S. air strikes in Iraq and Syria against Kataib Hezbollah, an Iran-backed militia group. U.S. officials said on Sunday that the attacks were successful, but warned "additional actions" may be taken to defend U.S. interests.
Global benchmark Brent crude traded at $68.33 a barrel and U.S. West Texas Intermediate stood at $61.74.
Oil prices were also supported by a bigger-than-expected decline in crude inventories in the United States, the world's biggest fuel consumer. Stockpiles fell by 5.5 million barrels in the week to December 20, far exceeding a 1.7-million-barrel drop forecast in a Reuters poll, government data showed on Friday.
