The S&P/ASX 200 Index (ASX: XJO) slumped on Wednesday, dropping 0.12% to close at 7,255.7 points.
Its day in the red came on the back of the 2023 federal budget, delivered on Tuesday night.
It included $14.6 billion of spending aimed at easing cost-of-living pressures. However, that might have increased the likelihood of further interest rate hikes, as my Fool colleague Bernd reports.
Back to the bourse, and the S&P/ASX 200 Health Care Index (ASX: XHJ) posted today's biggest gain, lifting 1%.
But most sectors traded lower in today's session. The S&P/ASX 200 Financials Index (ASX: XFJ) fell hardest, sliding 0.5%.
Meanwhile, the S&P/ASX 200 Energy Index (ASX: XEJ) and the S&P/ASX 200 Materials Index (ASX: XMJ) both dropped 0.3%.
