Fonterra’s February forecast pegged the 2025-26 season farmgate milk price at $8.10-8.50 per kilogram of milk solids, up from the $7.90-8.30 range announced in December. Before dairy farmers start celebrating or banks start worrying, it’s worth examining what drives these forecasts and which assumptions could prove wrong.

Global Dairy Market Dynamics

World dairy prices strengthened in January, with whole milk powder averaging USD $3,420 per tonne, up 6% from December. Skim milk powder and cheese showed similar gains. The question is whether these increases represent genuine demand strength or temporary supply constraints.

Chinese import volumes increased in December and January, reversing several months of softer demand. Whether this represents inventory rebuilding or sustained consumption growth will determine if current price levels hold through Q2.

European production continues running slightly below year-ago levels due to high feed costs and environmental restrictions in several countries. Reduced European supply supports global prices, but the situation could reverse if feed costs normalize or policy changes occur.

New Zealand Production Outlook

New Zealand milk production for the current season tracks 2.5% below the previous year through January. Weather conditions in key dairy regions have been adequate but not exceptional, limiting peak production volumes.

Some farmers reduced stocking rates or dried off cows earlier than usual given feed costs and uncertain price forecasts. These decisions reduce supply in the near term but reflect rational economic calculations when margins are tight.

The production shortfall relative to previous years means New Zealand will capture less benefit from current elevated prices than if production were running ahead. This constraint frustrates farmers but supports global pricing by limiting supply growth.

Currency Impacts

The NZD/USD exchange rate averaged 0.587 in January, slightly weaker than the 0.595 average for 2025. Currency movements significantly impact farmgate prices since dairy exports price in USD but farmers receive NZD.

Fonterra’s forecast assumes NZD/USD around 0.59 for the remainder of the season. If the Kiwi dollar strengthens beyond 0.60, achieving the upper end of the forecast range becomes difficult even if global dairy prices hold firm.

Currency volatility adds planning complexity for farmers and processors. Some farmers use forward exchange contracts to lock in rates, but many remain exposed to currency fluctuations alongside commodity price movements.

Cost Inflation Pressures

Even if the milk price forecast proves accurate, farmer profitability depends heavily on input costs. Fertilizer prices moderated from 2024 peaks but remain elevated historically. Feed and fuel costs similarly came down but not to pre-2022 levels.

Labor costs continue rising across New Zealand agriculture, with minimum wage increases and tight labor markets pushing wages up 4-6% annually. Dairy farms are labor-intensive operations where wage inflation directly impacts margins.

The gap between gross revenue per kilogram of milk solids and actual farmer profit has widened over recent years as costs grew faster than milk prices. An $8.30 payout in 2026 leaves farmers less well off than the same price would have in 2020.

Fonterra’s Product Mix Strategy

Fonterra continues shifting toward higher-value products beyond commodity powders. Specialized nutritional products, cheese, and consumer-ready items generate better margins than bulk commodity exports.

The product mix shift matters for farmgate prices because higher realized values from Fonterra’s sales translate to better farmer payouts. However, the transition requires sustained investment and takes years to fully implement.

Some farmers question whether Fonterra’s value-added strategy will deliver promised returns or represents wishful thinking about escaping commodity price cycles. The track record shows incremental progress but not transformative change yet.

Alternative Processors and Competition

Independent processors like Synlait and Westland offer competitive farmgate prices in regions where they operate. This competition prevents Fonterra from reducing payouts without losing suppliers, which benefits farmers but constrains Fonterra’s flexibility during difficult periods.

The competitive environment also pressures all processors to maintain procurement volumes, sometimes leading to optimistic forecasting that raises farmer expectations. When forecasts subsequently decline, it creates financial planning problems for farmers who budgeted based on initial higher projections.

Some farmers switched processors in 2025 based on competing price forecasts, only to find that final payouts converged across suppliers. The switching costs and disruption rarely justified the marginal differences in outcomes.

Regional Variation and Microclimates

National average forecasts mask significant regional variation. Waikato and Taranaki production patterns differ from Canterbury and Southland, with implications for individual farm economics.

Farms with irrigation infrastructure managed better through variable weather conditions, producing more consistent yields. Non-irrigated operations faced more volatility, with some regions experiencing temporary drought stress that limited production.

These regional differences mean some farmers will significantly outperform or underperform national average figures. Farm-level planning requires understanding local conditions rather than just relying on industry-wide forecasts.

Environmental Regulation Impact

Freshwater regulations limiting nitrogen discharge continue affecting farm management decisions. Some operations reduced stocking rates to meet nitrogen caps, lowering production potential regardless of milk prices.

The environmental compliance costs vary by farm depending on previous practices and land characteristics. Farms that operated close to regulatory limits face higher costs than those with larger margins for adjustment.

These regulations represent permanent rather than cyclical constraints on production. Even if dairy prices spike to levels that would historically trigger production expansion, regulatory limits will constrain supply response more than in previous cycles.

Climate and Weather Wildcards

The forecast assumes normal weather patterns for the remainder of the season. Any significant drought or flooding events could materially impact production and therefore actual farmgate returns.

El Niño Southern Oscillation patterns shifted toward neutral in late 2025. The current forecast period doesn’t face strong El Niño or La Niña influences, reducing weather-related uncertainty compared to some recent seasons.

However, climate variability overall has increased, making “normal” weather less reliable as a forecasting assumption. The range of plausible outcomes widened even as central forecasts improved.

Financial Planning Implications

For farmers making decisions about capital investment, debt servicing, or operational changes, prudent planning probably assumes the lower end of Fonterra’s range rather than the midpoint or upper bound.

Conservative assumptions about milk prices and commodity markets in general have served farmers better than optimistic planning over the past decade. The sector’s volatility punishes those who overextend based on favorable price periods.

Some farmers are now working with agricultural consultants and technology providers to improve forecasting and scenario planning capabilities. Better data and analytical tools help navigate uncertain price environments, though they can’t eliminate the fundamental uncertainties.

Comparison with Other Export Sectors

Dairy price volatility remains high but not exceptional compared to other New Zealand export commodities. Forestry prices fluctuate similarly, while meat prices show different but equally challenging patterns.

The concentration of New Zealand export earnings in volatile agricultural commodities creates macroeconomic challenges. When multiple sectors face simultaneous price declines, the broader economy suffers regardless of good management by individual farmers or firms.

Diversification toward less volatile export sectors makes economic sense nationally but requires decades of investment in other industries. In the meantime, New Zealand remains dependent on agricultural commodity prices to a degree that other developed economies are not.

What the Forecast Really Tells Us

Fonterra’s forecast represents the best current estimate based on available information and reasonable assumptions. It’s not a promise or guarantee, and conditions could easily shift in ways that move the final payout outside the forecast range.

Farmers and rural communities should view the forecast as one input to planning rather than definitive guidance. Maintaining financial buffers and flexibility remains essential given the inherent uncertainties in commodity agriculture.

The forecast suggests 2026 won’t be a disaster for dairy farmers, but it’s unlikely to be a boom year either. That moderate outlook feels appropriate given current market conditions and trends.
