The latest Global Dairy Trade (GDT) trading event delivered a noticeably softer price tone: the overall GDT Price Index fell 4.3% from the previous auction, with the weighted average price at US$4,043 per tonne and total volume sold around 41,465 tonnes — largely whole milk powder (WMP) and skim milk powder (SMP). The result shows broad pressure across milk powders and milkfat products, with butter and anhydrous milkfat (AMF) both down.

Why butter and milk fat eased — the supply / demand picture
Several factors explain today’s declines for butter and AMF:
-
Higher milk availability / seasonal flows. Global milk collections have shown resilience in a number of key producing regions in recent weeks. When milk supplies expand, more milkfat and powder capacity becomes available to the market, easing short-term upward pressure on fat markets. The auction volumes sold (over 41k tonnes) were dominated by powders, underlining how current flows are shaping price discovery.
-
Softening demand for butter in some key end-uses. Foodservice and industrial demand for butter can be cyclical — when consumer demand for bakery and premium butter declines or when buyers switch to cheaper fat alternatives (including AMF or blended fats), spot butter buying calms. Today’s auction suggests buyers were contained, contributing to the modest fall in butter prices (-2.5%).
-
Relative competitiveness of AMF and blends. AMF often trades as a cost-competitive alternative to bulk butter for processors. Small moves in AMF availability and pricing (AMF also down ~2.6%) can pull on butter values as industrial buyers balance cost vs fat specification.
-
Powder weakness feeding into sentiment. Larger percentage falls were recorded in WMP (-5.3%) and SMP (-5.8%) — these declines press liquidity and trader sentiment across the board. When powders are weak, market participants often pull back across the curve, reducing speculative and physical buying that would otherwise support fat prices.
Not all categories fell — where buyers stepped in
Cheddar was a notable exception, recording a +3.6% lift in the weighted average. This suggests targeted buying interest from cheese processors or regional users who are currently restocking or facing tighter local cheese availability. Divergence like this highlights the product-specific nature of demand: powders respond to global feed stocks and export demand, fats respond to cream balances and industrial switching, and cheese markets follow their own supply/demand dynamics.
Implications for traders and downstream industries
-
Processors and traders should expect continued volatility: the GDT platform remains the global benchmark and price discovery mechanism; today’s 4.3% index fall underscores how quickly sentiment can shift when powders and fats realign.
-
Butter users (bakeries, foodservice) may find short-term relief in lower butter prices, but the market can tighten rapidly if cream availability reduces or if seasonal demand recovers. Hedging strategies using forward contracts or alternative fat sourcing remain advisable.
-
Exporters and policy watchers should note the concentrated tonnage in powders — countries with significant WMP/SMP exposure will feel the impact of the price decline more than those focused on value-added cheese or speciality fats.
Bottom line
Today’s GDT auction shows a market adjusting to greater milk flows and weaker powder demand, with butter and AMF easing alongside sharper falls in SMP and WMP. Cheddar bucked the trend, highlighting how demand remains uneven across product types. For market participants, the key watch items are cream balances in major producing regions, buying patterns from large industrial purchasers in Asia and the EU, and whether downstream demand (foodservice/industrial) recovers in coming weeks — any of which could reverse today’s soft tone.
