What moves the zinc price

The zinc price is quoted per tonne on the London Metal Exchange. About half of all zinc is used to galvanize steel against rust, which ties the price to construction, infrastructure and car production, with brass alloys and die casting taking most of the rest. Metal Sentinel returns the live quote with the unit stated in each response.

  1. Galvanized steel demand

    Construction, bridges, roofing and vehicle bodies all use zinc-coated steel. Chinese property and infrastructure spending is the largest swing factor.

    Steel output rises zinc rises

  2. Mine supply and treatment charges

    Smelters charge miners a treatment charge to turn concentrate into metal. Falling charges signal a shortage of concentrate; rising charges signal a glut. Traders read them as a leading indicator.

    Treatment charges fall zinc rises

  3. Smelter energy costs

    Zinc refining is energy intensive, and European smelters cut output during the 2021 to 2022 power crisis. Electricity prices therefore affect refined supply.

    Smelter power costs climb zinc rises

  4. Exchange inventories

    LME and Shanghai warehouse stocks show how much refined zinc is available. Low inventories support the price and widen the premium for nearby delivery.

    Inventories drain zinc rises

About Zinc

What is Zn?

Zinc is a bluish-white base metal used mainly for galvanizing: coating steel to prevent corrosion in products from car bodies to power pylons. It is also a major alloying element in brass and an essential micronutrient. China is by far the largest producer, so its mining and smelting capacity concentrates supply risk. Spot zinc is quoted on the London Metal Exchange.

Zinc price questions

Questions people ask before they wire the zinc price into a product.

What is a treatment charge?

It is the fee a smelter deducts from the metal value when buying zinc concentrate from a mine. Annual benchmark charges are negotiated each year and tell you whether mines or smelters have the upper hand.

Why does zinc follow the steel market?

Galvanizing is its biggest use. When steel output for construction and cars rises, zinc demand rises with it, and the reverse in a downturn.
