Australian Equity Fund Returns and the Weak Australian Dollar

What the Currency Is Actually Telling You

Most commentary on Australian equities is focused on commodity prices. That focus, while understandable, is incomplete. The AUD/USD cross is currently doing more work than the iron ore price or copper spot price in determining the earnings outcomes of ASX-listed companies. Investors who are not accounting for the currency dimension are working with an incomplete picture, and in the current environment, that gap is consequential.

A weaker Australian dollar delivers two distinct effects simultaneously. It lifts reported AUD earnings for every Australian company with USD-denominated revenue, and it makes Australian assets cheaper to acquire for foreign capital. Both effects are operating right now. Neither is fully reflected in how most investors are positioning their portfolios.

The Earnings Translation Mechanism Is Direct and Immediate

When the AUD weakens against the USD, Australian companies earning overseas revenue receive more Australian dollars for every unit of that revenue when they report. The underlying business has not changed. The commodity price in USD terms may be identical. But reported AUD earnings are higher, and so is the capacity to pay dividends.

This is not a marginal effect. For a resources producer with 80 per cent of revenue denominated in USD, a sustained move in the AUD/USD cross shifts earnings materially without any change in production volume or commodity price. It is one of the most powerful but consistently underweighted drivers of ASX earnings outcomes, and it is active right now.

Applying a dispassionate analytical framework, the implication is clear: investors assessing ASX resources exposure need to run the currency analysis before they run the commodity price analysis. The sequence matters.

"Currency is consistently underweighted in how investors think about Australian equity returns. When the AUD weakens, every dollar of overseas revenue becomes worth more when it comes home. For resource producers selling iron ore, copper, or LNG in USD, a sustained move in the AUD/USD cross can add or detract meaningfully to reported earnings without any change in the underlying commodity price. Most investors focus on the commodity and miss the currency entirely." - Emanuel Datt, Chief Investment Officer, Datt Capital

A Weaker AUD Attracts Foreign Capital Into Australian Equities

The second effect is structural and operates independently of earnings entirely. When the AUD falls, Australian assets become cheaper to acquire for investors holding USD, GBP, EUR, or JPY. A foreign institutional allocator buying ASX-listed equities gets more Australian asset per unit of their domestic currency. That is a valuation argument that has nothing to do with the earnings per share line.

The practical consequence is increased foreign capital inflow into Australian equities during periods of sustained AUD weakness. That incremental demand supports valuations across the market, not just in sectors with direct USD revenue exposure. Australia's structural attributes, a stable legal framework, deep natural resource endowment, and consistent economic growth, make it an already attractive destination for global capital. A weaker AUD lowers the entry cost further.

One might conclude from watching domestic commentary that Australian equities are valued primarily on earnings and dividends. The reality is that foreign capital flows, driven in part by currency dynamics, play a meaningful role in supporting ASX valuations that domestic earnings models do not capture.

"A weaker AUD makes the entire ASX cheaper on a relative basis for global investors. That is a demand argument for Australian equities that operates completely separately from earnings. When both effects are running simultaneously, the combination is significant and is easy to miss if you are only watching the earnings per share line." - says Emanuel.

Labour and Fuel Determine Who Captures the Tailwind and Who Does Not

The answer to which producers actually benefit is unambiguous: it is those with the cost discipline to hold margins when input costs rise. The currency tailwind is not evenly distributed. It concentrates in producers with lean cost structures and dissipates in those running elevated input costs.

Labour is the largest operating cost for most Australian mining operations. Skilled labour availability has remained structurally constrained since 2022. Wages across Western Australia and Queensland are elevated, and the pipeline of skilled workers has not materially improved. A producer paying elevated labour cost per tonne absorbs a significant portion of any currency or commodity tailwind before it reaches reported earnings.

Fuel is the second variable. Diesel powers mobile equipment, haulage, and ore processing. With Brent holding above US$100 per barrel and domestic fuel prices elevated by the Middle East conflict, miners with high fuel intensity per tonne face a direct and sustained cost headwind. The producers who cannot control these two inputs will find the external tailwind largely absorbed at the operational level.

"We look carefully at labour intensity per tonne and fuel consumption per tonne of ore processed when assessing whether a producer can actually convert a favourable external environment into earnings. A producer with structural cost advantages captures far more of that tailwind than one running elevated input costs. The commodity price tells you very little about the actual earnings outcome without that operational data." - Emanuel highlights.

Small Cap Producers Carry the Most Direct Leverage

Diversified majors hedge their currency exposure across geographies and commodity types. Their earnings are smoothed. Small cap and pure-play producers do not carry those natural hedges. Their earnings move directly and immediately with the AUD/USD cross, amplifying both upside and downside.

In the current environment, where AUD weakness and elevated commodity prices are aligned, the producers with lean cost structures are capturing earnings growth at a rate the large caps cannot replicate. This is where the active small cap opportunity is most concentrated. The external environment is favourable. But the returns will not be distributed evenly across the sector. They will concentrate in producers with high-grade deposits, low fuel and labour intensity, and management disciplined enough to hold costs while conditions are supportive.

Identifying those producers is primary research work. It cannot be done at the index level. The Datt Small Companies Fund applies exactly this framework to ASX small cap equities.

Portfolio Relevance

For investors assessing Australian equity fund exposure, three critical factors must be considered: AUD/USD direction, underlying commodity price outlook and producer cost structure third. Investors who begin and end with the commodity price are making incomplete assessments. The currency creates the environment and the cost structure determines who benefits from it. Finding the producers with genuine cost advantages and meaningful USD revenue exposure requires the kind of primary research that passive and index-level allocation cannot perform.

Conclusion

A weaker Australian dollar is doing significant analytical work that most investors are not fully accounting for. It lifts reported earnings for ASX companies with USD revenue, attracts foreign capital into Australian equities on a relative value basis, and concentrates the benefit in producers with lean cost structures. Labour and fuel are the counterweights that determine how much of the external tailwind reaches the bottom line. Understanding the interaction between these variables, rather than commodity prices in isolation, is where the genuine analytical edge sits in the current market.
