Threadneedle's Latin America fund deputy Katy Dobson will assume control of the £950m business.
Dobson replaces Jules Mort, who will remain in the number two position, while also focusing on the company’s segregated institutional mandates.
Prior to joining Threadneedle last year, Dobson managed $1.5bn in Latin American funds at Pictet Asset Management.
Under Mort’s control the Latin America fund returned 17.5% over the year to 20 August, ranking 8th out of 67 in the IMA Specialist sector, according to Morningstar statistics.
A Threadneedle spokeswoman said Dobson brings considerable experience managing large sums of money in the region.
“She is obviously delighted to be number one, and it is very much business as usual,” she said.
The change to the Latin America fund comes as Threadneedle continues its push into emerging markets.
“We recently acquired a hedge fund house, Convivo Capital, which specialises on emerging markets,” the spokeswoman says.
“It shows we are committed to strong expansion in emerging markets.”
