World stocks have hit a four-month high on hopes of progress in trade talks between the United States and China, with a dovish backdrop at major central banks also helping push markets back into the black.
US President Donald Trump said negotiations with China were going well and suggested he was open to extending the deadline to complete them beyond March 1.
Up to now, it was assumed US tariffs on $US200 billion ($A279 billion) worth of Chinese imports would rise to 25 per cent from 10 per cent if no trade deal was reached by then.
Asian shares on Wednesday soared on Trump's comment, and European stock indices also strengthened, pushing the MSCI world equity index , which tracks shares in 47 countries, to a four-month high.
Deutsche Bank's chief strategist Jim Reid said the newsflow was encouraging, despite signs that more progress was needed.
"The overall feeling is that it is one step forward, three-quarters of a step back at the moment. So positive momentum but still fragile," he said in a note.
While hopes for a trade deal between the world's two largest economy are seen as the primary driver for world stocks, dovish central bank messages are also playing a part.
New York Fed President John Williams on Tuesday said he was comfortable with the level US interest rates were at and that he saw no need to raise them again unless economic growth or inflation shifted to an unexpectedly higher gear.
Investors are also looking to the release on Wednesday of minutes from the Federal Reserve's January meeting, at which policymakers effectively signalled no further rate hikes and possible tweaks to its balance sheet normalisation.
In Europe, expectations have been growing that the European Central Bank will restart a program to provide long-term cheap loans to banks to boost a faltering economy, while the Bank of Japan has flagged its readiness to ease further.
MSCI's broadest index of Asia-Pacific shares outside Japan rose as much as 1.1 per cent to mark its highest levels since October 2.
Hong Kong's Hang Seng gained as much as 1.3 per cent to six-month highs, while Korea's Kospi and Taiwan's index recovered to levels last seen in early October. Japan's Nikkei added 0.6 per cent to two-month highs.
On currency markets, the dollar steadied against a basket of major currencies, after suffering its biggest one-day loss of the month on Tuesday. It had also recorded big slides against the euro and sterling.
The greenback strengthened 0.2 per cent against the yen after Japan recorded its biggest annual drop in exports in January for more than two years, and on recent dovish Bank of Japan signals.
Markets were also focused on newsflow on the Brexit front, with sterling holding most of its gains following a 1 per cent surge on Tuesday as British Prime Minister Theresa May headed to Brussels to try push negotiations forward.
The yuan rose as much as 0.6 per cent against the dollar , its biggest intra-day gain in more than a month, after Bloomberg reported on Tuesday that the United States was seeking to secure a pledge from China that it will not devalue the currency as part of a trade deal.
Oil prices hovered near 2019 highs, supported by OPEC-led supply cuts and US sanctions on Iran and Venezuela, but further gains were capped by soaring US production and expectations of an economic slowdown.
International Brent crude futures stood at $US66.30 ($A92.59) per barrel, having hit a three-month high of $US66.83 ($A93.34) per barrel earlier this week.
