Nigeria is Africa’s most populous country, with an estimated population of 230 million in 2024 according to the UN, making it the continent’s largest market. As West Africa’s leading economy, it plays a central role within ECOWAS. However, this leadership comes amid significant economic pressures and regional realignment.
Nigeria stands as Africa’s most populous nation, with approximately 230 million inhabitants in 2024, according to the World Bank and the United Nations.
This massive population makes it the continent’s largest consumer market and a key player in Africa’s economy. Its GDP is estimated at between 243 and 250 billion US dollars in 2024, largely driven by hydrocarbons. It alone accounts for nearly 35% to 40% of ECOWAS GDP, confirming its central role in the sub-region.
“We will work together to pursue inclusive economic integration in West Africa. We must show commitment and ensure that our peoples, who have suffered enough, benefit. We must offer a prayer here so that, in the future, for the regional economy, reconciliation and development, we commit to democracy and promote democracy and the rule of law.”
Bola Tinubu, President of the Republic – Nigeria
Nigeria holds a pivotal, structuring role within the 12-state ECOWAS bloc, which comprises nearly 450 million people. Its economy, heavily reliant on oil exports for almost 90% of its revenue, significantly impacts the region’s overall growth, projected at 3.7% for 2024. However, this deep dependence on hydrocarbons simultaneously poses a vulnerability, threatening the economic stability of both Nigeria and the entire region.
“From the origin of the Treaty of Lagos in 1975 to this momentous meeting here in Accra, ECOWAS remains a pillar of integration and a beacon of hope for more than 400 million citizens in our region. Remarkably, our journey over the past five decades has not been without challenges. We have faced political instability, economic difficulties, infrastructure deficits and security threats, yet we remain undaunted.”
Bianca Odumegwu-Ojukwu, Minister of State for Foreign Affairs – Nigeria
In this complex regional context, West African states face a growing number of challenges: political instability, security tensions in the Sahel, inflation and pressure on local currencies. These difficulties reinforce the need for closer cooperation and better economic coordination within ECOWAS. Nigeria, as the main contributor, thus finds itself at the centre of expectations regarding regional stability and economic recovery.
“We must place our young people, who are dynamic, creative and resilient, at the centre of our agenda. We must invest in education, innovation and skills development to unlock Africa’s full future potential. We must always seek peace in order to achieve the collaborations necessary for development. We must also improve economic cooperation, support intra-regional trade and ensure that the African continental framework becomes a vehicle for real transformation. A prosperous Africa is good for Africa and the world.”
Bianca Odumegwu-Ojukwu, Minister of State for Foreign Affairs – Nigeria
Despite its economic fragilities, Nigeria retains a major strategic role in West Africa. With its demographic weight, a market of more than 230 million consumers, significant energy resources and strong political influence, it remains an indispensable pillar of ECOWAS. However, its regional leadership is now facing growing competition from other West African economies, signalling a gradual reshaping of regional balances.
