The US inflation data is in the limelight as investors try to guess the trajectory of policy tightening by the US Federal Reserve. The CPI may have slowed to 0.2 per cent in February for an unchanged year-on-year rate of 1.8 per cent, according to economists.
If inflation is lower than expected it will add to the view that the Fed is only likely to lift rates three times this year, rather than four. Markets had already pared back their US rate hike expectations after a slowdown in the pace of US wage growth late last week.
On the day, the US dollar has been on a "raggedy trend down", said Imre Speizer, Westpac Banking Corp market strategist. "It's weakening into that number of some fear of a disappointment."
Looking ahead, he said domestic investors will then shift their focus to Thursday's domestic product data, with economists tipping the economy to have expanded 0.8 per cent on quarter in the fourth quarter.
While the data is fairly historic, "it is the most important piece of economic data you can get because it is the number that wraps up the whole economy".
Speizer said it was particularly important to the central bank "when it is surprised by the number".
