Why CBN Reset Interest Rates — Cardoso Explains Decision Behind Nigeria’s 23% Monetary Policy Rate
The Governor of the Central Bank of Nigeria (CBN), Olayemi Cardoso, has explained why the apex bank adjusted the country’s benchmark interest rate from 26.5 per cent to 23 per cent, insisting that the decision should be understood as a reset rather than a conventional interest rate cut.
Cardoso clarified while speaking at the ongoing International Monetary Fund (IMF) and World Bank annual meetings in Bangkok, Thailand, where he discussed Nigeria’s monetary policy decisions and the factors influencing the country’s economic outlook.
According to the CBN governor, the adjustment was necessary because the official monetary policy rate had become disconnected from prevailing rates in the money market. The situation weakened the effectiveness of the bank’s monetary policy framework and made it more difficult for the benchmark rate to influence financial market conditions as intended.
The September decision reduced the Monetary Policy Rate (MPR) by 350 basis points, bringing it down from 26.5 per cent to 23 per cent. However, Cardoso stressed that the adjustment did not represent a fundamental shift towards an easier monetary policy stance.
Explaining the rationale behind the decision, Cardoso said market conditions had changed following measures introduced by the central bank to address economic challenges.
He explained that the prevailing money market rates had fallen below the official policy rate, creating a gap that reduced the effectiveness of the CBN’s principal monetary policy instrument.
The governor said the reset was intended to bring the benchmark rate closer to prevailing market realities and improve the transmission of monetary policy decisions across the financial system.
In monetary policy, transmission refers to how decisions taken by a central bank influence borrowing costs, lending, spending, investment and inflation throughout an economy.
When the benchmark rate does not adequately reflect market conditions, changes in the official rate may have a weaker or less predictable impact on financial institutions and businesses.
By recalibrating the rate, the CBN aims to restore its effectiveness as the main signal guiding monetary policy and financial market operations.
Despite the reduction in the benchmark interest rate, Cardoso maintained that Nigeria’s monetary policy stance remains restrictive.
A restrictive monetary policy generally involves maintaining relatively high interest rates and other measures designed to moderate borrowing, spending and demand in order to control inflation.
The governor explained that the CBN would continue to prioritise price stability and would not abandon its tight monetary policy approach until inflation had made sufficient progress towards the bank’s single-digit target.
He acknowledged that the exact timeline for achieving single-digit inflation remained uncertain.
The distinction between an operational reset and a broader policy easing is important because a lower benchmark rate does not automatically mean the central bank has abandoned its efforts to control inflation.
The CBN’s position is that the adjustment is intended to make its existing monetary policy framework function more effectively, rather than signal an immediate shift towards cheaper credit across the economy.
Cardoso also pointed to improvements in Nigeria’s macroeconomic conditions as part of the explanation for the timing of the adjustment.
These developments include moderating inflation, improved conditions in the foreign exchange market and stronger external reserves.
According to the CBN’s September monetary policy assessment, Nigeria’s headline inflation eased slightly to 15.39 per cent in August 2026 from 15.43 per cent in July.
The country’s external reserves also stood at $55.25 billion as of September 18, 2026, providing an additional buffer against external economic pressures.
Furthermore, Nigeria recorded real gross domestic product growth of 4.43 per cent in the second quarter of 2026, reflecting continued economic activity despite existing challenges.
These indicators contributed to the central bank’s assessment that economic conditions could accommodate the operational adjustment without undermining its efforts to reduce inflation.
However, the CBN has maintained that future monetary policy decisions will depend on economic data and the progress made in controlling price increases.
Cardoso also highlighted improved coordination between the country’s fiscal and monetary authorities as an important factor supporting the policy framework.
He explained that the authorities had taken steps to improve communication and cooperation, including signing a memorandum of understanding intended to strengthen coordination between fiscal and monetary policies.
Fiscal policy concerns government revenue, expenditure and borrowing, while monetary policy focuses on managing monetary conditions and influencing inflation and economic activity.
Better coordination can help reduce conflicting policy signals and improve the effectiveness of measures designed to support economic stability.
The governor also acknowledged that the CBN’s decision took some market participants by surprise. He said communication surrounding the announcement had been carefully considered to help explain the reasons behind the adjustment.
The episode highlights the importance of clear communication from central banks, particularly when monetary policy decisions differ from market expectations.
The reduction of the MPR to 23 per cent could influence borrowing costs and investment decisions, but its impact on businesses will depend partly on how commercial banks respond.
The MPR is the CBN’s benchmark policy rate; it is not the exact interest rate charged on every commercial bank loan.
Banks consider several factors when setting lending rates, including their funding costs, credit risks, operating expenses and prevailing financial market conditions.
Consequently, businesses should not assume that the 3.5-percentage-point reduction will automatically translate into an equivalent reduction in loan interest rates.
For small and medium-sized enterprises, the cost and availability of credit remain important concerns. Businesses seeking loans to expand operations, purchase equipment or manage working capital will be watching to see whether the adjustment leads to more favourable lending conditions.
Households may also monitor developments because borrowing costs can influence consumer loans, mortgages and other forms of credit.
Nevertheless, the extent of any benefits will depend on how effectively the new policy framework influences the wider financial system.
Although inflation has moderated, the cost of living remains a major concern for Nigerian households.
Food, transportation, housing and other essential expenses continue to influence the financial circumstances of families across the country.
The CBN has therefore emphasised that reducing inflation remains a central objective of its monetary policy approach.
Lower inflation would mean that prices rise more slowly, although it would not necessarily mean that prices return to previous levels.
The central bank must also consider potential risks from exchange rate movements, global energy prices, supply disruptions and increased domestic spending.
These factors could affect the pace at which inflation declines and influence future decisions on interest rates.
For this reason, Cardoso’s comments indicate that the CBN intends to retain a cautious approach even after adjusting its benchmark rate.
The effectiveness of the reset will become clearer as financial market conditions respond to the revised benchmark and subsequent economic data become available.
The CBN will need to assess whether the adjustment strengthens the relationship between its policy rate and actual market interest rates while supporting its inflation objectives.
For businesses and consumers, the immediate question is whether the changes will eventually translate into more accessible credit and improved economic conditions without reigniting inflationary pressures.
Cardoso’s explanation makes the central bank’s position clear: the reduction from 26.5 per cent to 23 per cent was intended to correct a misalignment between the official policy rate and market conditions.
The CBN maintains that this operational reset does not signal an abandonment of its restrictive monetary policy stance.
As Nigeria continues to navigate inflation, financing costs and broader economic reforms, the impact of the decision will depend on how effectively the revised framework influences the financial system and supports sustained price stability.
