Westpac Banking Corporation Earnings Preview: Why May 5 Could Move ASX Bank Stocks

Westpac Banking Corporation Earnings Preview: Why May 5 Could Move ASX Bank Stocks

May 3, 2026

SYDNEY, May 4, 2026, 00:01 AEST

Westpac Banking Corporation is set to release its first-half results at 10 a.m. Tuesday in Sydney. Investors will be watching the bank’s bad-debt provisions, lending margin, and the sale of its RAMS mortgage portfolio. Westpac’s investor page confirms a webcast for the half-year results on May 5, with the financial calendar also marking that date for interim results and the dividend announcement.

The result drops the same day the Reserve Bank of Australia is tipped to bump its cash rate by 25 basis points to 4.35%, a move that hits both mortgages and business loans. According to a Reuters poll, ANZ, Commonwealth Bank of Australia, and National Australia Bank all see that level as the likely ceiling. Westpac, on the other hand, is looking for 4.85%. “The outlook for the cash rate beyond May is necessarily less certain,” Westpac chief economist Luci Ellis said. Reuters

Westpac faces a double-edged sword with rising rates. If loan rates climb ahead of deposit costs, bank income could see a lift. But households and small businesses—already battling fuel and cost-of-living strains—may get pinched harder. Margins and arrears should stand out on Tuesday.

Westpac laid out the details in its ASX statement. First-half lending climbed 4%, with deposits not far behind, up 3%. Thanks to ongoing productivity, expenses dipped by 2%. CET1, the closely-watched regulatory capital metric, improved over the second quarter. The bank expects its credit impairment charge—cash set aside against potential bad loans—to land at 10 basis points of average gross loans. Westpac flagged that the looming RAMS sale to Pepper Money, KKR, and PIMCO will trim reported net profit after tax by A$75 million. Meanwhile, a bout of volatility shaved the Treasury and Markets net interest margin to 7 basis points in 2Q26, down from 15 basis points the previous quarter.

Westpac shares ended May 1 at A$38.45, slipping 0.13% for the day and sitting under A$42.59—the price at the April 13 close, right before the bank’s pre-result ASX release. ASX trading kicks off at 09:59:45 and wraps at 16:00 Sydney time, so there’s just Monday’s session left ahead of Westpac’s results.

The bar for comparison just moved. On May 1, ANZ Group posted a first-half statutory profit of A$3.65 billion, with cash profit hitting A$3.78 billion. Its cost-to-income ratio landed at 49.4%, and the CET1 ratio came in at 12.39%. ANZ’s interim dividend holds steady at 83 cents—a number Westpac holders now have to measure up against for costs, capital strength, and payout.

Provisioning isn’t just on Westpac’s plate—it’s a sector-wide thread now. NAB flagged in its latest update that first-half credit impairment charges are set to jump, possibly hitting A$706 million. “Banks are proactively building buffers,” Solaris Investment Management’s Michael Bell said, calling out the more vulnerable cyclical pockets. For Atlas Funds Management’s Michael Haynes, the risk is clear: higher energy prices could mean a step-up in bad debts. Reuters

But it’s not a simple trajectory. Should fuel costs recede, or if the pass-through into other prices is softer, Westpac economists note the RBA might need to do less than their current forecast—potentially shifting the risk for margins and arrears fast. On the flip side, if the shock drags on, borrowers get squeezed from both higher repayments and steeper fuel bills, which spells a tougher scenario for provisioning.

Tuesday shapes up as a straightforward check: Westpac has to deliver solid loan growth and keep a tight grip on costs, with bad-debt charges under control. If the bank falters—particularly on guidance or the dividend—the share price drop in April starts to look less like a blip and more like a signal.

  • Metro Petroleum Stores Raided in Tobacco Crackdown
    August 11, 2026, 6:56 AM EDT. Police raided more than 100 Metro Petroleum petrol stations across Australia in a coordinated push to stop illegal tobacco and vapes. The Australian Federal Police and Border Force, with help from 250 officers across 15 agencies, searched the outlets after intelligence tied some independent operators to crime groups. Metro Petroleum supplies the fuel, but store operators run each outlet on their own. The company said it had no involvement or knowledge of the alleged crimes and promised to work with authorities. AFP Crime Command said illegal tobacco supports organised crime. About 80% of tobacco in Australia comes from the black market. The investigation is still running as agencies review what they found.
