Purchasing strengthened in the core autocatalyst and industrial markets, which accounted for 94% of gross demand.
A 4 per cent contraction in platinum's use in autocatalyst applications represented a divergence from the broad trend of growing global vehicle production, explained by the weakness in platinum's key automotive market, Europe, coupled with the twin draw of substitution (to palladium in diesel applications) and thrifting the intensity of metal use.
