FRANKFURT, Jan 3 (Reuters) – Germany’s conservative Christian Social Union (CSU), sister party to Friedrich Merz’s CDU, on ​Saturday said it will help push ahead with ‌the Chancellor’s call for a single European stock exchange to support European ‌listings and economic growth.

“We support the strengthening of European capital markets and a European bourse in order to keep successful German companies in the country,” said a draft internal ⁠CSU paper, that ‌was obtained by Reuters.

“We intend to take on a clear leadership role in this process ‍and ensure that the headquarters of a European bourse are located in the European Union’s biggest economy, Germany,” said the paper.

It ​was issued ahead of three-day party meetings starting ‌on Tuesday in the Bavarian town of Seeon.

Merz first presented the plan in October saying it would strengthen Europe as a business location.

Among backers of a unified market for capital inside the EU are European Central Bank President ⁠Christine Lagarde, German finance minister ​Lars Klingbeil and Bundesbank president Joachim ​Nagel.

Fragmented markets with different exchanges under different rule-books and supervision set the EU at a ‍disadvantage vis-a-vis the ⁠United States with its powerful New York Stock Exchange, say backers of the plan.

European exchanges say that ⁠initial public offerings in Europe are held back by reduced local ‌liquidity pools.
