Nigeria significantly increased its military expenditure in 2025, with spending rising by 55 percent year on year to reach US$2.1 billion, according to new data reflecting the country’s escalating security challenges.
The sharp increase highlights the growing pressure on Nigerian authorities to respond to multiple threats across different regions. Armed insurgency in the northeast, banditry in the northwest, separatist tensions in the southeast, and rising cases of kidnapping and organised crime have collectively strained the country’s security architecture.
The spending surge aligns with broader global trends, as countries ramp up defence budgets in response to rising geopolitical instability. Worldwide military expenditure has reached record levels, underscoring a shift toward prioritising security in national budgets.
For Nigeria, however, the drivers are largely domestic. The long running conflict with extremist groups, including factions linked to Boko Haram, continues to demand sustained military operations. At the same time, rural insecurity and attacks on communities have forced the government to expand deployments and invest in equipment, intelligence, and personnel.
The increase in spending reflects not only operational costs but also efforts to modernise the armed forces. This includes procurement of military hardware, improved surveillance systems, and enhanced logistics to support troops in remote and volatile areas.
Despite the rise in funding, questions remain about effectiveness. Security analysts have repeatedly pointed out that higher spending does not automatically translate into improved outcomes, particularly where issues such as coordination, intelligence gaps, and governance challenges persist.
There are also economic implications. Nigeria is balancing increased defence expenditure with broader fiscal pressures, including debt servicing, inflation, and the need for investment in infrastructure and social services. Allocating more resources to security could limit spending in other critical sectors unless revenue generation improves.
At the same time, the human cost of insecurity continues to rise. Displacement, loss of livelihoods, and disruptions to agriculture and trade are affecting millions of Nigerians, further complicating the country’s economic outlook.
The surge in military spending also reflects a regional dimension. Instability across parts of the Sahel and West Africa has created cross border security risks, pushing countries like Nigeria to strengthen their defensive capabilities.
While the government views the increased budget as necessary, experts argue that a long term solution will require more than military force. Addressing underlying issues such as poverty, unemployment, and weak local governance is seen as critical to reducing the drivers of conflict.
The data ultimately underscores a difficult reality. Nigeria is spending more than ever on security, yet the scale and complexity of threats suggest that the path to stability will require a broader, more integrated approach beyond defence alone.
