Shares in Contemporary Amperex Technology (CATL), the world's largest electric vehicle battery manufacturer, jumped more than 5% in Hong Kong trading today, 27 July 2026, amid market chatter of a major new supply agreement with an unnamed European automaker. The rally marks a sharp reversal from recent weakness in the sector, which had been weighed down by concerns over slowing EV demand in China and Europe.
The move rippled through global markets, with UK-listed companies exposed to the battery supply chain also benefiting. Shares in Johnson Matthey, which produces battery cathode materials, rose 1.2%, while mining giant Rio Tinto, a key supplier of lithium and copper, added 0.8%. The FTSE 100 edged up 0.3% to 8,412 points, supported by gains in industrial and mining stocks.
Analysts at Shore Capital noted that any large-scale deal would underscore CATL's continued dominance in the battery sector, despite efforts by Western firms to build alternative supply chains. 'A fresh contract with a European OEM would be a significant vote of confidence in CATL's technology and cost structure,' they said in a note. 'It also suggests that European carmakers remain heavily reliant on Chinese battery suppliers for the foreseeable future.'
For UK investors and pension holders, the rally highlights the interconnected nature of global supply chains. Many UK pension funds have indirect exposure to CATL through global equity funds and index trackers. The broader EV supply chain remains a key driver of returns for funds invested in commodities and industrial metals, though volatility persists amid geopolitical tensions between China and the West.
The battery sector has been under pressure this year due to oversupply concerns and a slowdown in EV adoption rates. However, today's move suggests that large-scale contract wins can still spark significant short-term gains. Investors are now watching for official confirmation of the rumoured deal, which could further boost sentiment across the sector.
