The S&P/ASX 200 Index (ASX: XJO) put on a rocky performance on Wednesday, eventually closing the session 0.02% higher at 7,237.2 points.
The fall came as Reserve Bank of Australia (RBA) governor Philip Lowe addressed the National Press Club after the central bank decided to pause interest rate hikes yesterday, saying:
The decision to hold rates steady this month does not imply that interest rate increases are over. Indeed, the board expects that some further tightening of monetary policy may well be needed to return inflation to target within a reasonable timeframe.
Among those leading the Aussie bourse on Wednesday was the S&P/ASX 200 Health Care Index (ASX: XHJ). It gained 0.7%, led by the Imugene Limited (ASX: IMU) share price, which gained 7.7% on news of its VAXINIA trial.
Meanwhile, the S&P/ASX 200 Communications Index (ASX: XTJ) rose 0.8%.
Weighing on the index, however, was the S&P/ASX 200 Energy Index (ASX: XEJ). It fell 0.6% with Whitehaven Coal Ltd (ASX: WHC) shares coming in as its worst performer.
