# What are the key risks to Westpac’s growth trajectory?

# Key Risks to Westpac's (WBC AU) Growth Trajectory

Drawing on CLSA's June 2025 Australian Banks note (where WBC is rated **U-PF with TP A$27.50 vs price A$33.21 — implied –17.2% downside [4]**) and Westpac's own **1H26 results briefing (May 2026)**, the principal risks to Westpac's growth trajectory cluster into five buckets:

## 1. Replicating-Portfolio Deficit vs Peers (FY26 — Most Distinctive Risk)
This is CLSA's central single-name concern and management has now confirmed it.

- WBC does **not** have the replicating-portfolio tailwind of peers in FY26 because of the shorter duration of its hedge — CLSA flags this as a "material headwind relative to peers" [1][2].
- Management confirmed FY26 H2 will deliver only **~2bps of replicating-portfolio benefit** and just **~3bps for full-year FY27**, both below peers; CFO Nathan Goonan explicitly conceded WBC "had more of the replicating benefits earlier than some of our peers" and that "in the outlook will be a little bit less."
- This forces WBC to compete harder on deposit pricing to defend its franchise, putting incremental pressure on margins.

## 2. Net Interest Margin Compression
- **Core NIM fell 4bps to 1.78% in 1H26**, with timing differences following RBA rate changes detracting 2bps [9].
- Management guides that "**overall lending margins to continue to edge lower**" in 2H26 and that the rate of compression has been "more pronounced in institutional this period" [10].
- CLSA: "broader sector headwinds from rate cuts cycle coupled with the competition and mix impacts" [2].
- Upside to NIM is contingent on "easing competition" — i.e., the base case is continued competitive pressure [3].

## 3. Macro / Credit-Quality Risk — Middle East Conflict & Energy-Intensive Sectors
- Management is now expecting "**a more pronounced slowdown in the Australian economy this year, as energy supply pressures flow through to higher and more persistent inflation**" [5].
- A new **portfolio overlay (~AUD 100m) was added for energy-intensive sectors** (transport & storage, construction, agriculture); base-case provisions assume higher unemployment and lower GDP.
- **Credit impairment charges increased to 10bps of average gross loans (vs 4bps prior period)** — a 2.5x step-up [7].
- **Capital sensitivity is material**: a one-notch downgrade across energy-intensive exposures would lift RWAs by **~AUD 4bn = ~11bps CET1 hit** [8].
- Front-book signals are softening: "**more pronounced slowing in home lending, our most interest-rate-sensitive portfolio. Mortgage applications have eased in April**," with hardship applications and personal-loan enquiries rising modestly [6].

## 4. Cost / Project Unite Execution Drag
- CLSA expects **cost growth of ~4% in 2H25**, driven by amortisation, +A$70–110m investment spend, and salary annualisation [2].
- Project Unite benefits are real but **back-end loaded — material flow-through not until FY28–29**, and investment will drag costs in the interim [2].
- CLSA: "WBC has also been growing **below system in mortgages as RAMS continues to run down**" — a structural growth headwind [2].
- WBC's own commentary acknowledges that "performance has been constrained by complexity and legacy systems" and that the new "Catalyst" operating model is multi-year, not immediate.

## 5. Valuation / Sector Stance
- CLSA maintains an **Underweight stance on the Australian banks sector**, citing "more rate cuts likely adding pressure to bank earnings, buybacks slowing and the tail risk of rotation towards resources" [2].
- Within the sector preference order is **ANZ > NAB > Westpac > CBA**; CLSA views WBC as "**over valued in the near term**" given likely earnings headwinds [2].
- WBC has ~A$1.1bn remaining in the buyback as price support, but CLSA argues the share price has already performed and the new-CEO narrative is largely priced in [2].

## Summary Risk Matrix

| Risk | Time Horizon | Magnitude | Source |
|------|-------------|-----------|--------|
| Replicating-portfolio shortfall vs peers | FY26 | Material — defines relative underperformance | CLSA [1][2] |
| Core NIM compression (–4bps to 1.78%) | Immediate | Moderate; lending margins to "edge lower" further | 1H26 call [9][10] |
| Energy-sector credit deterioration (1-notch DG → 11bps CET1) | Cyclical (12–18m) | High asymmetric tail risk | 1H26 call [8] |
| Impairments stepping from 4 → 10bps | Already realised | Moderate, trending higher | 1H26 call [7] |
| Cost growth ~4% / Unite investment drag | FY26–FY28 | Moderate; benefits delayed to FY28–29 | CLSA [2] |
| Mortgage share loss as RAMS runs down | Structural | Low–moderate | CLSA [2] |
| Mortgage application slowdown + household stress | 6–12 months | Moderate | 1H26 call [6] |
| Middle East conflict / fuel-price shock to household income | Ongoing | High | 1H26 call [5] |
| Valuation — already-priced new-CEO narrative | Near-term | Moderate | CLSA [2] |

**Net assessment**: Growth headwinds are dominated by a *self-inflicted* relative disadvantage (replicating portfolio timing + Unite investment drag) layered on top of a *cyclically deteriorating* macro backdrop (Middle East shock, energy-sector credit overlays, softening mortgage demand). The first is what makes WBC a relative underperformer vs ANZ/NAB; the second is what could turn earnings headwinds into outright downgrades if credit migration accelerates.
