Middle Eastern debt issuance surged 40 per cent in the first half of 2013, the strongest period on record, according to new data released by Thomson Reuters. Debt raised reached $26bn, including $20.8bn of investment grade corporate debt in the first two quarters of the year, accounting for around 80 per cent of debt capital markets activity. In a further sign of a brighter outlook for the financial sector, debt capital markets underwriting earned banks $102m, more than double the income of the same period last year, and the best first-half performance ever, the report said.
