Materials Stocks: Aluminium, Fertilizer and the Commodity Cycle

Two Commodities, One Framework

The materials sector on Oslo Børs is dominated by two companies whose fortunes are tied to very different commodities — but follow the same cyclical logic:

Norsk Hydro is one of the world's largest aluminium producers. Its earnings are primarily driven by the London Metal Exchange aluminium price, with energy costs — particularly Norwegian hydropower — as the key cost variable.

Yara International is the world's largest publicly listed fertilizer company. Its margins are determined by the spread between natural gas prices (its main input) and urea/ammonia prices (its main output).

Both companies have significant competitive advantages — low-cost, renewable energy for Hydro; massive global distribution for Yara — that mean they survive downturns and emerge stronger. The question is always: when is the cycle in your favour?

Norsk Hydro: Buy Signals

Aluminium Below $1,700/tonne

Global aluminium production has a cash cost floor of approximately $1,700–1,900/tonne for the highest-cost producers. When prices fall into this range, significant production curtailments follow — setting the stage for the next price recovery.

Norsk Hydro's break-even is among the lowest in the industry thanks to its captive hydropower. This means it survives when others don't — and benefits disproportionately when the market recovers.

P/B Below 0.7

Hydro owns physical aluminium smelters, hydropower assets, and bauxite/alumina operations with very long asset lives. When the market values these at 70 cents on the dollar or less, the risk/reward has historically been highly favourable.

Yara International: Buy Signals

Urea Below $200/tonne

Urea prices below $200/tonne are at or below the marginal cost of production for high-cost producers, particularly those using coal-based feedstock in China and Eastern Europe. At these levels, production curtailments typically begin — supporting future prices.

Urea prices above $600/tonne have historically been associated with supply shocks (such as the 2021–2022 energy crisis) and are unsustainable. Yara's stock typically peaks in these periods.

The Gas-to-Urea Spread

Yara's profitability is really the spread between gas input costs and fertilizer output prices. When European gas is expensive and urea is cheap, margins collapse. When gas normalises and crop prices support fertilizer demand, margins expand rapidly. Monitoring this spread is more insightful than looking at either price in isolation.
