Global debt issuance is on course to hit a record high in 2016 as figures showed sales this year topped $5 trillion (£3.9 trillion) at the end of September.

Debt issuance rose to $5.02 trillion in the nine months to September 22, according to Dealogic, putting 2016 on course to beat the all-time high of $6.6 trillion recorded in 2006.

Record low interest rates have encouraged countries and companies to issue debt as central banks around the world try to stimulate growth.

The data also showed corporate issuance of investment-grade debt reached a record high of $1.54 trillion since the start of the year, up from $1.41 trillion in the same period a year earlier.

Dealogic's figures also highlighted the impact of the Brexit vote.
