"For headline CPI we look for 0.4 percent [increase], lower than the consensus 0.6 percent pickup. For the underlying rate, we look for a rise of 0.6 percent, from 0.5 percent in Q1 but in line with the trend over the past year, apart from Q4's 0.9 percent outlier," said economists at National Australia Bank in a note.

New Zealand markets will also be in focus on the back of second-quarter consumer inflation figures.

A Reuters poll shows economists expect the consumer price index to have risen 0.4 percent in the three months to June, which would take the annual rate to 1.8 percent, the highest since 2011.

Japan will post trade data for June at 7:50am SIN/HK. In May, the economy's trade deficit narrowed to 909 billion yen ($8.9 billion), marking the 23rd consecutive monthly shortfall and investors will be watching whether the declining trend will continue.

That would top the bank's final reading of 50.7 last month, but still well below the seven-month high Beijing's June official figure of 51.

Meanwhile, the Reserve Bank of New Zealand is due out with its monetary policy decision. National Australia Bank expects the central bank to hike its overnight cash rate for a fourth time in a row, by 25 basis points to 3.5 percent following June's quarter-point cut.

"To us it is simply too early to back off its stated tightening cycle when domestic demand remains so robust. With the economy evolving broadly in line with June MPS forecasts, the RBNZ commentary is likely to generally support its previous rate intentions," said the bank.

Japan releases consumer price inflation before Tokyo's 8am market open, which is seen remaining above 3 percent for the next 12 months, according to Moody's Analytics.

Finally, South Korea also releases advanced second-quarter gross domestic product (GDP). Following the first quarter's 0.9 percent monthly rise, Moody's is expecting Thursday's data to reveal a sharp slowdown to 0.5 percent, citing weak job creation and exports.
