Inflation targeting: CBN urges fiscal discipline by states

Nigeria's Central Bank is signalling a critical vulnerability in its shift toward formal inflation targeting: state governments remain fiscal wildcards that could derail monetary policy effectiveness.

The Central Bank of Nigeria (CBN) has publicly emphasised that successful adoption of an inflation-targeting (IT) framework depends on disciplined fiscal policy from Nigeria's 36 states and federal government. This warning reflects a structural challenge that has plagued monetary policy implementation in Africa's largest economy for decades—the disconnect between central bank constraints and sub-national spending autonomy.

## What Is Nigeria's Inflation Targeting Framework?

Inflation targeting is a monetary policy regime where the central bank sets a specific inflation range (Nigeria's is 6–9% as of 2023) and uses interest rates and other tools to keep actual inflation within that band. Unlike previous frameworks where the CBN operated with broader discretion, IT requires transparency, credibility, and **coordination with fiscal authorities**. The CBN transitioned formally to IT in 2022, but early execution has proven turbulent—headline inflation touched 34.6% in October 2023 before moderating.

## Why State Fiscal Discipline Matters Now

Here's the mechanics: when state governments spend excessively on wages, contracts, or transfers without corresponding revenue (through taxes or internally generated revenue), they inject money into the economy. This demand-side pressure pushes inflation upward, forcing the CBN to raise interest rates higher and longer than necessary. Higher rates then contract credit, hurt businesses, and reduce government revenue—a vicious cycle.

Nigeria's federal structure compounds this. States control ~40% of government expenditure but have weak revenue bases—most depend on federal allocations. When those allocations tighten (as during oil price crashes), states borrow heavily or delay vendor payments, creating fiscal spillovers that fuel inflation.

## The Real Risk: Credibility Collapse

The CBN's credibility in inflation targeting hinges on its ability to hit targets. If state spending consistently forces inflation above the 6–9% band, investors lose faith in the framework. This means:

- **Higher risk premiums** on Nigerian government debt (pushing borrowing costs up 200–300 basis points)
- **Weaker naira** as foreign investors demand compensation for inflation risk
- **Delayed private investment** in manufacturing and services—firms can't plan pricing in a high-inflation regime

Evidence from Mexico, Chile, and South Africa (countries that successfully adopted IT) shows that fiscal discipline at all government levels was non-negotiable to success.

## What CBN Is Actually Signalling

The CBN's public call for state fiscal discipline is not rhetoric—it's a **credibility marker**. By explicitly linking IT success to state behaviour, the CBN is:

1. Shifting responsibility to elected officials (covering itself politically)
2. Signalling to markets that IT won't work without fiscal reform
3. Creating pressure on President Tinubu's administration to enforce fiscal rules

Nigeria's Fiscal Responsibility Act (2007) gives the executive tools to audit and sanction states, but enforcement has been sporadic. The CBN's emphasis suggests this may change.
