Grandage will join the City firm to lead its structured trade and commodity finance practice, helping to organise it across a range of jurisdictions.
The practice includes London-based infrastructure chief Martin McCann and Singapore-based partner Yu-En Ong.
Norton Rose head of banking Jeremy Edwards confirmed that Grandage would be “co-ordinating the offerings around the network”.
He added: “I believe Nick was particularly drawn by the international direction of Norton Rose and the quality and ambition of the trade and commodities team.”
Grandage, who spent five years in Singapore and Hong Kong while at Dentons, has acted for major banks including BNP Paribas, Fortis, Standard Chartered and HSBC.
