With growth in major emerging markets set to slow in 2014, yield-hungry investors will be forced to look at riskier frontier markets like Colombia or sub-Saharan Africa, a director at global risk consultancy Control Risks told CNBC on Tuesday.

Chris Torrens, the director of global risk analysis for Europe and Africa at Control Risks, said one of 2014's key trends would be investors looking to frontier markets – the less developed end of the investable emerging market spectrum – as established emerging markets had now "emerged" and therefore growth was waning.
