The uncut nickel cathode premium in Rotterdam fell to $250–400 per tonne on September 22.
Fastmarkets reported a 13.3% decline from the preceding weekly range.
Higher energy costs and weaker-than-expected European demand weighed on the market.
A trader said unsold European material was adding pressure to near-term premiums.
The nickel briquette premium also declined, while the 4×4 cathode premium remained unchanged.
