LONDON — Shares of Britain’s Metro Bank were briefly suspended from trading twice early Thursday, in a volatile session that saw the stock shed more than 29% from the Wednesday close.

They have since slightly pared losses, having resumed again trading shortly after 9:00 a.m. London time.

The London Stock Exchange, which lists the stock, confirmed to CNBC that the brief suspensions were triggered by its circuit break mechanisms because of the extent of the volatile drop.

The halts followed reports that the bank was trying to raise £600 million ($727 million) in debt and equity, according to Reuters. The challenger bank, which launched in 2010, has a market cap of less than £100 million.

Metro Bank said in a statement that it is currently considering “how best to enhance its capital resources,” with a particular focus on a £350 million bond due to mature in October 2025.

Investors traded more than 1.6 million shares immediately after the stock market opened Thursday, according to FactSet. Typically, less than 100,000 Metro Bank shares change hands every hour.

Shares of the bank have lost around two-thirds of their value since mid-February.
