Stanley, who is commonly referred to as Jes, brings nearly 40 years of experience in banking and financial services, having worked for over 30 years at J.P. Morgan as a commercial banker.
He will leave his current role as managing partner of BlueMountain Capital to replace former chief executive Antony Jenkins who was fired in July following a dispute with board members.
Earlier this month Stanley’s role was confirmed by Barclays’ board members to the BBC.
According to a tweet by the BBC’s business editor Kamal Ahmad at the time, Barclays plans to keep its investment focus when Staley is appointed. When Jenkins was ousted from Barclays earlier this year, it was over a disagreement regarding his strategy to remove the focus from the bank’s troubled investment arm.
Stanley said: “We will be committed to preserving and enhancing the trust that is the foundation of Barclays’ reputation. We must also continue the focus on shareholder returns which John McFarlane has mandated.
“Barclays is a very valuable franchise: from its retail and commercial banking presence in the UK, its strength in cards and payments, its strong position in Africa, to its Investment Bank. Maximising the potential of this franchise means building on our competitive advantages and developing new ones in order to generate strong returns on capital. If we do this, increased value for our shareholders will follow at the same time as Barclays’ long history of leadership is continued and enhanced.”
