Westpac Banking Corp heads into its half-year result with a tighter spotlight on credit costs after energy-market shocks linked to the Middle East conflict pushed the lender to raise provisions and hit Treasury and Markets income. Reuters described Westpac as Australia’s No. 2 bank by assets and said its provisions for potential bad debt were at their highest since the COVID-19 pandemic.
The timing is awkward. Westpac is due to release its first-half 2026 results at 10 a.m. on Tuesday, the same day investors expect the Reserve Bank of Australia to make its next rates call.
That matters because banks live off the net interest margin, the gap between what they earn on loans and what they pay for deposits and funding. A Reuters poll found 30 of 33 economists expect the RBA to raise the cash rate by 25 basis points to 4.35% on May 5; AMP economist My Bui said “ inflation is basically too high in Australia,” while Westpac chief economist Luci Ellis said the rate outlook beyond May was “less certain.” Reuters
Westpac has already framed the first-half story. In an ASX release, the bank said lending grew 4%, deposits rose 3%, core net interest margin was stable in the second quarter, and productivity work helped cut expenses by 2%; it also flagged weaker Treasury and Markets margin from rate volatility, a new overlay for energy-intensive sectors, and a credit impairment charge of 10 basis points of average gross loans.
There is also a clean-up cost. Westpac said the sale of its RAMS mortgage portfolio to a consortium including Pepper Money, KKR and PIMCO remains on track for completion in the second half of 2026, but transaction costs tied to the sale will cut reported net profit after tax by A$75 million.
The peer read-through is not simple. ANZ on Friday reported first-half statutory profit of A$3.65 billion and cash profit of A$3.78 billion, and Chief Executive Nuno Matos said the bank was delivering “materially better returns” as it simplified operations and reduced duplication. ANZ
NAB is another warning sign for the sector. Reuters said National Australia Bank expects A$706 million in first-half credit impairment charges and a roughly 20-basis-point hit to its common equity tier 1 ratio, a measure of core capital against risk-weighted assets.
For Westpac, the question is whether loan growth and cost cuts can offset softer markets income and higher bad-debt buffers. Investors will also look for how much of the RAMS hit is treated as a one-off item rather than a sign of more cleanup work to come.
But the risk cuts both ways. If oil and funding shocks fade quickly, some of the caution built into provisions may look heavy; if inflation sticks and the RBA lifts rates more than expected, households and small firms could come under more strain, eroding any margin benefit.
Westpac’s own economists are more hawkish than peers on rates. Reuters said ANZ, Commonwealth Bank and NAB expect the cash rate to peak at 4.35%, while Westpac forecasts 4.85%, leaving Tuesday’s result to land in the middle of a sharper debate about how long borrowers can absorb higher costs.
