The last time I interviewed Oliver Andrews was five years ago, just after he had reached the mandatory retirement age at the Africa Finance Corporation AFC. He had spent more than a decade at the infrastructure-oriented investment organisation, latterly as executive director and chief investment officer, and was widely regarded as one of the institution's intellectual architects.
He had helped mobilise tens of billions of dollars for roads, ports, power plants, industrial zones and logistics platforms across Africa. Many assumed he would step back, take advisory roles, perhaps join boards. Andrews himself sounded unconvinced.
"I was never going to be put out to pasture," he says now, with a mischievous smile. "I'm one of those horses that had to jump the fence."
