Volatile global markets a winner for IG

The collapse of rival MF Global and the unprecedented volatility of global stock markets in August saw IG Index, the world's largest spread-betting firm, increase profits by 28 per cent in its first half.

The company's revenues also rose by 28 per cent to £195m during the six months to November with pre-tax profits at £103m.

The UK still accounts for more than half of IG's revenues, but the firm's operations in Europe and Australia delivered 40 per cent-plus revenues growth.

In Australia the government has launched a consultation over the segregation of clients' money following the collapse of MF Global.
