<div id="readability-page-1">By Ashitha Shivaprasad and Pablo Sinha Dec 30 (Reuters) - Platinum prices are on track for their strongest monthly rally in nearly four decades in December, fuelled by the EU's U-turn on its 2035 combustion-engine ban, a tight supply backdrop and rising investment demand for ‌precious metals. Platinum and palladium, both used in autocatalysts that reduce car exhaust emissions, have surged this ​year as U.S. tariff uncertainty and a rally in gold and silver ‍helped offset long-term headwinds from the rise of electric ⁠vehicles. The EU's plan unveiled ⁠in December is &#34;a steroid jab for PGMs, prolonging their use in catalytic converters&#34;, analysts at ‌Mitsubishi said. &#34;Not only is the extension indefinite, ​but the EU will require ongoing tighter emission levels, which by extension will require higher PGM loadings.&#34; Platinum, also used in ⁠other industries such as jewellery, is ‍up 33% ​so far in December, its biggest jump since 1986, according to LSEG data. After hitting a record high of $2,478.50 per ounce on Monday, the ‍metal is heading for its biggest yearly growth on record of 146%. Its sister metals, palladium and rhodium, are up 80% and 95% respectively so far in 2025. Both platinum and palladium also benefited from defensive stock-building and tighter supply in the regional physical markets due to outflows to ​the ‍U.S. as Washington included the metals on the U.S. critical minerals list. The market expects more clarity on U.S. tariffs in January. The start ​of PGMs futures trading in China a month ago gave another boost, attracting heavy speculative flows and prompting the Guangzhou Futures Exchange to adjust price limits. These contracts are the first domestic price-hedging mechanism for the PGMs in the world's second-largest economy, which is also the top PGMs consumer, relying heavily on imports. &#34;If Chinese spot ​import buying remains elevated, the major test for platinum group metals will likely come after there is clarity on U.S. tariffs,&#34; Macquarie analysts said.
