Highlights

  • ASX small caps have underperformed large-cap stocks during Australia's higher interest-rate environment.
  • Several investment managers believe valuations have become attractive relative to the broader market.
  • Future performance remains closely linked to inflation trends, interest rates and investor risk appetite.
  • Earnings season and future RBA decisions are expected to remain key market catalysts.

Australia's small-cap sector has experienced significant volatility through the recent interest-rate cycle. While some investment managers see attractive valuations emerging, any sustained recovery is likely to depend on inflation easing and interest-rate expectations improving rather than on valuations alone.

Why this theme matters

Small-cap companies occupy the higher-growth end of the Australian sharemarket. The S&P/ASX Small Ordinaries Index tracks companies ranked outside the ASX 100 but within the ASX 300.

Compared with large-cap businesses, many smaller companies typically have greater exposure to economic conditions, financing costs and investor sentiment. As a result, changes in interest rates often have a more pronounced effect on their valuations.

Background: How higher interest rates affected small caps

Australia's interest-rate tightening cycle placed considerable pressure on growth-oriented companies.

The Reserve Bank increased the cash rate from 0.10% in May 2022 to 4.35% by November 2023, with higher borrowing costs reducing investor appetite for companies whose earnings are expected further into the future.

Over longer periods, this translated into relatively weaker performance for the small-cap sector compared with larger Australian companies.

Although small caps staged a strong recovery during 2025 following earlier monetary easing, renewed inflation pressures and higher interest rates during 2026 created another period of market weakness.

The current environment

While several investment managers argue that Australian small-cap valuations now trade below historical averages relative to large-cap companies, any sustained re-rating is likely to require greater confidence that inflation is moderating and future interest-rate reductions become more likely.

The sector therefore remains closely tied to changing macroeconomic conditions rather than company-specific factors alone.

Supporting data and market observations

Recent market data illustrates both the opportunities and challenges facing the sector.

Over recent years, small-cap returns have been more volatile than the broader Australian market, reflecting changing expectations around interest rates, economic growth and corporate earnings.

Several professional investment managers have also suggested that valuation discounts relative to larger Australian companies are wider than historical norms. However, these remain market opinions rather than guarantees of future performance.

Potential opportunities

Supporters of the small-cap investment theme point to several positive factors.

Lower relative valuations could provide scope for improved returns if inflation moderates and borrowing costs eventually decline.

Improving corporate earnings, stronger capital-market activity and renewed investor confidence may also support smaller companies, particularly those with established business models and sustainable earnings growth.

Historically, periods following interest-rate peaks have often been favourable for higher-growth segments of the sharemarket, although each economic cycle differs.

Material risks and uncertainties

The principal risk remains inflation.

If price pressures remain elevated, interest rates could stay higher for longer, continuing to weigh on valuations across the small-cap sector.

Small-cap companies also generally face greater earnings uncertainty, lower trading liquidity and higher financing sensitivity than larger businesses. Valuation discounts can therefore persist for extended periods if economic conditions remain challenging.

Market volatility is also typically greater during periods of uncertainty, resulting in larger price movements than those experienced by large-cap stocks.

What investors should watch next

Key developments include:

  • Future Reserve Bank interest-rate decisions.
  • Inflation data and progress toward the 2–3% target range.
  • Corporate earnings during reporting season.
  • Capital-market activity, including IPOs, mergers and acquisitions, and equity raisings.
  • Whether valuation discounts between small-cap and large-cap companies begin narrowing.

These factors will help determine whether improving sentiment develops into a broader recovery.

Conclusion

Australian small-cap companies continue to offer both higher potential growth and higher investment risk than larger listed businesses.

Current valuations appear more attractive than in previous years according to several market participants, but the outlook remains closely tied to inflation, monetary policy and economic conditions. A recovery is possible if inflation eases and investor confidence strengthens, although future performance will ultimately depend on broader macroeconomic developments rather than valuation alone.
