US and European stocks stabilized Tuesday after Beijing pumped cash into the money market to soothe worries over the slowing Chinese economy.
Markets in London, Frankfurt and Paris all finished with modest gains, along with the S&P 500 in the US.
The advance was a reversal from Monday's bruising open to the 2016 trading year, when a deep decline in Chinese stocks prompted a global stock sell-off. Markets had also been rattled by rising tensions between Saudi Arabia and Iran over the Saudi execution of a prominent Iran-backed Shiite cleric.
On Tuesday, the benchmark Shanghai Composite Index ended down 0.3 percent after the People's Bank of China pumped 130 billion yuan ($20 billion) into the money market. News reports also said state-controlled funds bought stocks.
Investors are trying to ascertain whether China and the Saudi-Iran rift "should be something that we should worry about for much of this year, or whether it was simply an opening day flash in the pan," said Sam Stovall, chief investment strategist at S&P Capital IQ.
"It's still unresolved."
Some analysts suggested that the turbulence that afflicted Chinese equities on Monday had not yet run its course.
"It's an unstable situation when local investors are selling to a government buyer, it can only last so long," said Jasper Lawler, a market analyst at CMC Markets UK.
"There are still worries about the stability of the Chinese economy and the ability of the rest of the global economy to come to terms with the new China, one that no longer looks to double-digit GDP growth as the norm," said analyst James Hughes at trading firm GKFX.
"Markets have not coped well with this up to now."
London finished with a gain of 0.7 percent, while Paris and Frankfurt each rose 0.3 percent. The S&P 500 added 0.2 percent.
