Dubai: Greece’s main stock index tumbled more than 23 per cent during early trade as the markets reopened after a five-week gap.

The Athens Stock Exchange General Index fell more than 22 per cent to 615.61 at 11.58 am.

The Greek market came to a halt in June as Prime Minister Alexis Tsipras ended bailout talks with creditors by asking voters to decide in a referendum whether to accept the terms offered in exchange for emergency loans.

The nation was forced to shut down banks and impose capital controls.
