National Australia Bank Shares Downgraded As Analysts Raise Concerns

National Australia Bank shares (ASX:NAB) have been downgraded by two analysts over the past 24 hours, putting a dampener on sentiment. Morgan Stanley go to a bearish Underweight rating from Equal Weight, slashing its price target to A$39.80 from A$43.50, as the investment bank warns that Australia’s major lenders are “priced for perfection” after a strong run through 2024 and early 2025.

NAB shares have delivered a solid 5.52% gain year-to-date, outperforming several banking peers and reflecting market confidence in the bank’s franchise strength and business banking dominance. The stock’s resilience through 2025 makes JPMorgan’s downgrade particularly noteworthy, signalling that the investment bank believes much of the upside has been priced in while new headwinds emerge on the credit and capital fronts.

The downgrade represents a significant shift in sentiment toward one of Australia’s big four banks and comes alongside a broader sector call in which Morgan Stanley moved its industry view on Australian banks to Cautious from In-Line. The firm argues that while the major banks delivered solid results during February’s reporting season, the risk of both earnings downgrades and trading multiple de-ratings is now rising materially.

According to Morgan Stanley’s 2025 outlook on Australian banks, the majors benefited throughout 2024 from better-than-expected net interest margins, benign credit conditions, and strong investor flows into defensive income stocks. However, the firm now contends that 2024 represented “as good as it gets” for the sector, with limited room for further positive surprises as competitive pressures intensify, funding costs rise, and the tailwinds from earlier rate hikes fade.

The 9% reduction in National Australia Bank’s price target reflects Morgan Stanley’s view that the stock is vulnerable to a double hit: potential earnings disappointments as revenue momentum slows, coupled with multiple compression as markets reassess premium valuations across the sector. The bank’s shares had been trading near historically elevated price-to-earnings ratios following several years of operational improvements and consistent capital returns to shareholders.

Morgan Stanley’s analysis highlights several pressure points for the Australian banking sector in 2025. Net interest margin tailwinds that supported earnings growth are dissipating as deposit costs reprice higher, while competition in both mortgage and business lending markets is eroding pricing power. The firm also points to rising cost pressures from wages and regulatory compliance, alongside uncertainty about how long loan-loss charges can remain at cyclically suppressed levels.

The investment bank’s scenario analysis suggests that in a “bumpy landing” for the Australian economy, the major banks could face earnings per share downgrades of approximately 10% versus current market consensus, potentially leading to negative total shareholder returns over a twelve-month horizon. National Australia Bank, with its relatively large exposure to small and medium-sized enterprise lending, faces particular sensitivity to any deterioration in business conditions.

Despite the cautious stance, Morgan Stanley acknowledges that the structural health of Australia’s banking system remains robust. Capital positions are strong, provisioning levels are conservative, and dividends are likely to be maintained rather than cut even in weaker economic scenarios. The firm frames its downgrade as primarily a valuation and relative performance call rather than a fundamental concern about business viability or systemic risk.

JPMorgan Downgrade NAB Shares To Neutral

JPMorgan cut its rating from Overweight to Neutral, slashing the price target to A$46.10 from A$47.90, citing mounting concerns over short-term impairment charges and potential capital impacts from credit risk migration despite the lender’s strong top-line growth positioning.

The downgrade arrives at a pivotal moment for Australia’s banking sector, with multiple brokers reassessing valuations after the Big Four banks posted strong gains through fiscal 2025 and early 2026. NAB’s outperformance has brought its valuation metrics closer to historical peaks, reducing the margin of safety for equity holders as credit cycle dynamics shift.

The centrepiece of JPMorgan’s concerns is a dramatic escalation in credit impairment charges across NAB’s loan portfolios. Recent financial disclosures reveal that credit impairment charges surged to approximately A$254 million in the second quarter of 2025, more than tripling from A$81 million in the first quarter. For the full fiscal year 2025, NAB recorded a roughly 40% year-on-year increase in credit impairment charges, marking a clear inflection point in the credit cycle.

This sharp uptick represents a departure from the benign credit environment that characterised 2023 and early 2024, when impairment charges remained subdued and below long-term averages. The acceleration suggests that pockets of stress are emerging across NAB’s loan book, particularly in segments exposed to higher interest rates, cost-of-living pressures, and softer economic conditions.

Despite the rising impairment charges, NAB’s overall asset quality metrics remain solid by historical standards. The bank’s non-performing loan ratio stood at approximately 1.5% as of September 2025, anchored by a large portfolio of low-risk residential mortgages that continue to perform well. Mortgage arrears, which rose through March 2025, have since moderated over the six months to September, supported by lower interest rates and Australia’s resilient labour market.

Beyond the direct earnings impact of higher provisions, JPMorgan flagged concerns about capital dynamics as credit risk-weighted assets increase. NAB’s Common Equity Tier 1 ratio has been drifting lower from peak levels, pressured by a combination of loan growth, capital returns to shareholders through buybacks, and higher credit risk-weighted assets as loans migrate to higher risk categories.

While NAB’s CET1 ratio remains comfortably above regulatory minimums in the mid-11% range, the trajectory matters for markets assessing the bank’s capacity to sustain dividend growth and share buybacks. As credit risk-weighted assets climb, more capital is tied up supporting the same loan volumes, reducing the efficiency of the balance sheet and potentially constraining future capital management initiatives.

The credit risk migration dynamic reflects a natural evolution as economic conditions normalise and certain borrower cohorts face elevated stress. Small and medium enterprises, unsecured consumer lending, and segments of commercial property are areas where risk weights typically increase during softer economic periods, even when headline default rates remain contained.

Top-Line Growth Remains a Bright Spot

Despite the mounting challenges on credit and cost, JPMorgan acknowledged that NAB remains “strongly positioned on top-line growth,” reflecting the bank’s solid market position in business banking and its ability to grow loan volumes and net interest income. NAB’s business banking franchise is widely regarded as a competitive advantage, providing sticky customer relationships and cross-sell opportunities that support revenue generation.

Net interest income has held up well through the recent period, benefiting from a large book of variable-rate loans that repriced quickly as the Reserve Bank of Australia raised rates, while deposit costs lagged. As the rate cycle turns and the RBA cuts, the dynamics will shift, but NAB’s deposit franchise and pricing discipline should help defend margins relative to smaller competitors.

The bank’s ability to sustain top-line momentum will be crucial in offsetting the dual headwinds of higher credit costs and elevated operating expenses. If loan growth remains robust and net interest margins stabilise, NAB can potentially “earn through” the current challenges without requiring material changes to its capital return strategy.

Sector-Wide Valuation Reset Underway

JPMorgan’s downgrade is part of a broader reassessment of Australian banking sector valuations following strong share price performance through 2025. Multiple brokers have turned more cautious on the Big Four banks, with some carrying Sell ratings on NAB, Commonwealth Bank, and Westpac on the grounds that valuations have become stretched relative to earnings growth prospects and emerging credit cycle risks.

The shift in broker sentiment reflects a recognition that the “easy” phase of the post-pandemic recovery is over. Banks benefited from ultra-low credit costs, strong housing market activity, and rapid margin expansion as rates rose. Now, with credit normalising, margins under pressure from competition, and cost inflation persistent, the path to further multiple expansion looks more challenging.

For NAB specifically, the stock’s year-to-date outperformance has reduced the valuation gap versus peers, making it harder to justify premium multiples without clear evidence that credit costs are peaking and earnings momentum can reaccelerate. JPMorgan’s move to Neutral rather than Underweight suggests the bank sees risk-reward as balanced rather than outright negative, but the message is clear: the asymmetry that favoured bulls earlier in the cycle has diminished.

Looking Ahead

The critical question for NAB shareholders is whether the current uptick in credit impairment charges represents a normalisation from unusually low levels or the early stages of a more pronounced credit cycle downturn. If impairments stabilise around current levels and the Australian economy avoids recession, NAB’s strong franchise and capital buffers should allow it to navigate the period without material disruption to dividends or capital returns.

However, if economic conditions deteriorate further; whether through weaker employment, sharper falls in property prices, or renewed cost-of-living pressures, credit costs could continue rising, putting greater pressure on earnings and capital. In that scenario, the bank might need to slow buybacks, rebuild provisions more aggressively, or accept lower returns on equity for a period.

Markets will be watching NAB’s quarterly updates closely for evidence of whether credit impairment charges are plateauing or continuing to climb. Any guidance from management on the trajectory of credit costs, combined with updates on capital ratios and cost management initiatives, will be critical in shaping sentiment and determining whether the stock can regain upward momentum or faces further downgrades from the analyst community.

While the bank’s fundamentals remain sound and its credit ratings secure, the path to further share price gains has narrowed, leaving markets to weigh whether current valuations adequately reflect the shifting risk-reward balance in Australia’s evolving banking landscape.
