At noon AEST, the benchmark S&P/ASX200 had climbed to 8,152.5, up 10 points, or 0.13 per cent, with the broader All Ordinaries also sitting steady, up 10 points, or 0.13 per cent at 8,374.5.
The ripple effect from the US rate cut gave the ASX200 a jolt upon opening, shooting it to an all-time high of 8,186 before levelling out again at midday.
Financial market analyst Kyle Rodda from Capital.com said the 50 basis point reduction in US interest rates was a move normally reserved for financial turmoil or economic shock.
"Stocks pared gains, dollar bounced, and gold fell for the session," Mr Rodda said.
"Despite ostensibly giving what the market wanted, price action shifted during the press conference."
US Federal Reserve chair Jerome Powell spoke of "recalibration" at the press conference following the rate decision, but it's unclear whether the reduction will curb inflation as predictions signal another 50-point cut before the end of the year.
The decision by the US Federal Reserve came as a surprise to many economists who had predicted a 25 point cut.
"The Fed lowering rates by 50 basis points was only priced in as a 60 per cent probability, so it remains a bit of a dovish surprise," Saxo strategist John J. Hardy said.
