Taylor's principle on fiscal policy is that government debt, when it exceeds the economy's capacity to service it, creates compounding problems: higher interest rates that crowd out private investment, pressure to monetise the debt through inflation, and reduced fiscal capacity to respond to future crises. This is not a theoretical concern for Nigeria. Debt service as a proportion of government revenue has been among the highest in the world in recent years, meaning that a large fraction of every naira collected in taxes goes directly to servicing past borrowing rather than to current public services or investment. For a young Nigerian builder: understanding government debt is understanding the fiscal environment you are operating in and will operate in for the next three decades. The decisions made now about borrowing and repayment will shape what public resources are available for infrastructure, education, and health for your generation.
