Economic instability has become an unavoidable reality of doing business in Nigeria, and a few sectors feel their consequences as directly as project development and management.
From residential buildings and commercial centres to roads, industrial facilities, and public infrastructure, projects are conceived on assumptions about cost, financing, time, and market conditions.
Yet, those assumptions can change dramatically between conception and completion. Nigeria has experienced significant shifts in inflation, exchange rates, fuel prices, interest rates and the cost of imported inputs in recent years.
Although recent reforms have contributed to improved macroeconomic stability, inflationary pressures remain significant and external shocks continue to pose risks. The World Bank reported that Nigeria’s economy grew by about 4 per cent in 2025, supported by services, real estate, ICT and construction, while inflation remained elevated.
The IMF has similarly noted that renewed global fuel and food-price pressures can quickly feed into domestic inflation and transport costs. For project stakeholders, therefore, economic volatility is no longer something to be considered only after problems arise; it must be incorporated into project planning from the beginning.
The effect of economic fluctuations on projects is particularly visible in construction. A developer who prepared a bill of quantities, obtained financing and negotiated contracts at one price level may discover that the same project requires substantially more money several months later.
Inflation, exchange-rate movements, and fuel costs can affect cement, steel, electrical components, plumbing materials, finishing products, transportation, and equipment.
The situation becomes more complicated when projects depend on imported materials or equipment, because exchange-rate movements can alter the naira cost even when the international price remains unchanged. Recent Nigerian research has found significant relationships between exchange-rate volatility, imported material costs and budget revisions in construction projects.
This creates a dangerous cycle: rising costs produce budget pressures; budget pressures delay procurement; delays expose projects to another round of price increases; and the resulting cost escalation may threaten the original financial viability of the project. In practical terms, a project that looked profitable at commencement can become financially unattractive before completion.
Time, therefore, has become an economic variable in project management. Traditionally, project managers are expected to control the familiar triangle of cost, time and quality. In an unstable economic environment, however, these variables are increasingly interconnected.
A delay of three or six months is not merely a scheduling problem when interest is accumulating on borrowed funds, contractors are demanding revised prices and construction materials are becoming more expensive.
For property developers in Lagos, Abuja, Port Harcourt and other rapidly developing urban centres, delayed completion can also mean delayed rental income, delayed sales and additional security, maintenance and professional costs.
Globally, major infrastructure and construction projects face similar challenges from commodity-price movements, supply-chain disruptions, geopolitical tensions and changes in financing conditions.
The lesson is important for Nigeria: project schedules should not be treated as static documents. They should be actively monitored against economic developments, with realistic contingency provisions and clearly defined procedures for dealing with material changes in project conditions.
Financing is another area where economic fluctuations can fundamentally alter project outcomes. Higher interest rates increase the cost of borrowing and can make projects that appeared viable under one financial environment considerably more expensive under another.
Developers who rely heavily on debt financing must therefore examine not only the initial cost of a project but also the sensitivity of its financial returns to changes in interest rates, exchange rates, construction costs, occupancy levels and selling prices.
This is particularly important in Nigeria, where real estate development often involves substantial upfront expenditure and a relatively long period before revenue is realised. A sound feasibility study should consequently contain alternative scenarios rather than a single optimistic projection.
What happens if construction costs rise by 15 per cent? What if the exchange rate moves significantly? What if sales take longer than expected? What if interest rates remain high for another two years? Scenario analysis does not eliminate uncertainty, but it enables stakeholders to understand the consequences before committing substantial capital.
The contractual framework surrounding a project must also reflect economic reality. In periods of relatively stable prices, parties may be comfortable with fixed-price arrangements, but prolonged volatility can expose contractors, consultants and clients to risks that were not properly anticipated at contract signing.
Appropriate price-adjustment or escalation mechanisms, clearly defined variation procedures, realistic completion provisions and transparent risk allocation can help prevent economic shocks from becoming disputes.
This does not mean that every increase in cost should automatically be transferred to the client. Rather, the parties should determine in advance which risks each party is capable of managing and which risks require shared arrangements.
Professional advisers therefore have an increasingly important role to play. Quantity surveyors must provide realistic cost advice; architects and engineers should consider cost-effective specifications; valuers must pay attention to changing market evidence; financiers must stress-test project assumptions; and project managers must coordinate these perspectives into a coherent delivery strategy.
In a volatile economy, multidisciplinary collaboration is no longer a luxury-it is a project-survival mechanism. Technology and better information can further strengthen project resilience. Digital project-management platforms, cost-monitoring systems, Building Information Modelling, procurement databases and data analytics can give stakeholders earlier warning when project performance begins to diverge from the original plan.
Internationally, project organisations are increasingly using data-driven forecasting and scenario modelling to manage uncertainty in complex projects. Nigeria should move in the same direction.
A project manager should know not only how much has already been spent, but also why costs are changing, which procurement items are most vulnerable, how much exposure remains and what alternative actions are available.
For large projects, periodic economic-risk reviews should become part of project governance. Rather than waiting for a budget crisis, stakeholders can monitor inflation, exchange rates, fuel prices, interest rates and supply-chain conditions and incorporate the information into procurement and cash-flow decisions.
The objective is not to predict the future perfectly; it is to make the project sufficiently responsive to changing circumstances.
Ultimately, economic fluctuations do not necessarily make successful project delivery impossible; they make disciplined project management more important. Nigeria’s improving macroeconomic conditions provide opportunities for renewed investment, with the World Bank reporting stronger activity in sectors including real estate and construction, while the IMF has identified continuing external and domestic risks that require vigilance.
The appropriate response from project stakeholders is therefore neither excessive pessimism nor unrealistic optimism, but preparedness.
Developers must strengthen feasibility studies and financial planning; financiers must examine risk realistically; contractors must improve procurement and cost control; consultants must provide timely and evidence-based advice; and project managers must become more proactive in identifying and responding to economic risks.
The Nigerian project environment may remain uncertain, but uncertainty can be managed when stakeholders recognise that economic conditions are part of the project itself. In the years ahead, the projects that preserve cost, time, quality and ultimately value will increasingly be those managed not merely as construction or investment exercises, but as dynamic economic systems capable of adapting to change.
