A gauge of global stock markets edged near this year's peak while benchmark US Treasury yields and the dollar dropped after the Federal Reserve signalled possible interest rate cuts later this year.
MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.2 per cent while Japan's Nikkei gained 0.5 per cent .

The US Federal Reserve said on Wednesday it was ready to battle growing global and domestic economic risks with interest rate cuts beginning as early as next month, as it took stock of rising trade tensions and growing concerns about weak inflation.
The bulk of Fed policymakers slashed their rate outlook for the rest of the year by roughly half a percentage point, and Fed Chairman Jerome Powell said others agree the case for lower rates is building.
Many investors viewed the overall tone as more dovish than their expectations, sending the 10-year US Treasuries yield to as low as 1.986 per cent , its lowest level since November 2016.

Money market derivatives, such as Fed funds futures and overnight indexed swaps, are fully pricing in a rate cut of 25 basis points at next policy review on July 30-31, with about one-third chance of a bigger 50 basis point cut.
A total of 75 basis point reduction is priced in by the end of year.
However, such aggressive rate cuts when the stock prices are so close to record peaks would be rare, if not unprecedented, making some investors nervous about whether the Fed may be over-reacting.
“It seems the Fed is getting ahead of risk and doing whatever it takes to avoid downside implications due to a potential slowdown,” said Robin Anderson, senior global economist at Principal Global Investors in Des Moines, Iowa in the United States. “However, in the event inflation picks backs up, I'm apprehensive the Fed could be behind the curve if rates do in fact get cut too soon.”
Many investors think rate cut expectations could be rolled back if Washington and Beijing make some headway in their talks.
“While we expect 'insurance' rate cuts this year, we think the timing and magnitude of any policy easing is uncertain and somewhat dependent on US -China trade relations,” said Andrew Wilson, CEO of Goldman Sachs Asset Management for EMEA and global Head of fixed income.
