3 Min Read LONDON (Reuters) - British-based exchanges will once again offer trading in Swiss shares from next month, but it may take time to rebuild volumes, Britain’s finance ministry and exchanges said on Friday. The ministry has set out legislation in parliament that is expected to be approved quickly and allow platforms like Cboe, Aquis Exchange and London Stock Exchange’s Turquoise to be able to offer trading in Swiss shares from or just after Feb. 3. “Once in force, the Swiss State Secretariat for International Financial Matters (SIF) have indicated they will reciprocate by removing restrictions on UK trading venues,” a spokesman for the British finance ministry said.
