Westpac Banking Corporation (ASX: WBC) Stock Price Faces New Test After UNITE Update, Rate Reset

SYDNEY, March 30, 2026, 02:14 (UTC+11)

Westpac Banking Corp finished Friday at A$40.74, gaining 0.69%. Investors on Monday will be eyeing a new UNITE tech update and a 25-basis-point change on home loans set for March 31. 1

Timing could prove crucial here. Westpac wraps its half-year on March 31, with results set for release May 5. Investors now have to weigh up if firmer lending rates and steady funding are enough to counterbalance the price tag on the bank’s ongoing overhaul. In a March 26 presentation, Westpac maintained there’s been no tweak to the scope, schedule, or budget for UNITE. 2

On Friday, ASX data put the stock’s range between A$40.13 and A$40.94, with its 52-week low and high sitting at A$28.44 and A$43.32. Westpac shares, which surged to a record A$42.13 after first-quarter profit surpassed expectations in February, have since pulled back. 3

Westpac, during Thursday’s UNITE briefing, reported it has wrapped up discovery work on 57 separate initiatives, now organized into 10 work packages. For the first quarter of fiscal 2026, it noted an investment of A$195 million, with 73% of that figure already expensed.

Westpac spelled out what shareholders are getting for their money. The bank said its UNITE program has slashed the number of products by more than 70%, cut back over 700 processes, and dropped 180-plus applications. One part of commercial banking will move around 75,000 customer accounts to Westpac by December 2027. The annual direct payoff: roughly A$40 million. 4

Funding hasn’t been an issue. On March 26, Reuters said Westpac managed to sell a 1 billion euro AAA-rated covered bond—a bank debt instrument secured by ring-fenced assets, usually mortgages. The January 2031 paper landed at 28 basis points above mid-swaps and carries a 3.119% coupon. “Clear preference for top-rated issuers,” Citi’s Daeil Ahn observed, pointing to market volatility. Pramod Shenoi at CreditSights noted demand for covered bonds remains solid, calling them the safest asset class. 5

The rate picture isn’t getting any clearer. Earlier this month, the Reserve Bank of Australia bumped its cash rate up to 4.1%. Just last week, Assistant Governor Christopher Kent flagged that a drawn-out conflict in the Middle East could stoke inflation expectations. Westpac says its variable home-loan rates are set to jump 25 basis points starting March 31. Yes, higher rates can pad margins—but they also make life tougher for borrowers and raise the risk of bad loans down the track. 6

Westpac isn’t the only one feeling the pressure. Commonwealth Bank highlighted market-share gains across home and business loans as well as deposits in its February results, and NAB touched a record high following its quarterly update—a clear signal the big banks remain locked in a battle for growth. 7

Still, there’s a hitch—and investors are dialed in. Richard Wiles, who heads research at Morgan Stanley in Australia, flagged that while business and mortgage lending remain strong enough to support current conditions for another few quarters, he now sees loan losses as having already reached their lowest point. His view: “it will be difficult for banks to maintain current share prices.” Market Index, in a separate note, pointed out that Morgan Stanley holds an underweight rating on Westpac, raising issues like valuation, market-share plans and risks around UNITE’s execution. 8

Back in February, Westpac CEO Anthony Miller signaled that appetite for business and household credit should stay strong. Investors won’t have long to wait for the data; the half-year wraps up March 31, with interim results due on May 5. 9

  • Vulcan Energy Resources (ASX:VUL) Faces Wider Loss and Softer Sales Amid Valuation Debate
    March 29, 2026, 11:27 AM EDT. Vulcan Energy Resources reported a full year 2025 net loss of €69.58 million on sales of €7.35 million, posting wider losses and softer revenue. Despite this, the share price rose 3.48% in one day and gained 9.36% over a week, though it remains down 12.57% in the past month and 25.68% year to date. The stock trades at a price-to-book (P/B) ratio of 1.1x, well below the industry average of 1.9x and peers' 6.8x, suggesting potential undervaluation based on net asset value rather than earnings. However, sustained losses and project risks persist. A discounted cash flow (DCF) model values Vulcan at A$30.87, far above the current A$3.27 price, highlighting a market discount possibly driven by risk concerns.
