Why Australia's banking giants are thriving despite stubborn interest rates

• The Reserve Bank of Australia kept its official cash rate at 4.35% for the second consecutive meeting, noting that persistent inflation keeps potential monetary tightening on the table.
• Australia's major banks trade on price-to-earnings ratios spanning 17.6 to 28.2, underpinned by robust capital positions and stable credit quality.
• Sector executives project that high borrowing costs and slowing domestic economic activity will continue to influence credit growth and loan impairment expenses.
