Why issuing ₦10,000 and ₦20,000 notes is a dangerous move

A recent push by Quantus Economics to have the Central Bank of Nigeria (CBN) issue ₦10,000 and ₦20,000 notes has stirred up fresh debate in Nigeria’s economy. While the idea is touted as a way to make the naira easier to carry in an era of runaway prices, issuing such high denomination bills should be a definite no go for the government.

Why high value notes may seem practical

In their report, Quantus Economics argued that Nigeria’s highest note, the ₦1,000 bill, has lost much of its purchasing power, making it cumbersome for everyday transactions. They claim that carrying bulky stacks of low value notes slows trade, increases cash handling costs for banks and businesses, and poses security risks.

The report also emphasised that issuing larger notes is not inherently inflationary; rather, inflation is driven by cost push (rising input prices) and demand pull (high demand relative to supply).

Why this move threatens inflation and financial stability

Despite the argument for convenience, introducing ₦10,000 and ₦20,000 notes at this time carries heavy risks.

• Inflation signal: A major concern is the signal it sends. Larger bills often correlate with inflationary expectations and currency crises. Workers and small traders already facing shrinking purchasing power may interpret this as a sign of further devaluation or higher prices. The Nigeria Labour Congress (NLC) and the Organised Private Sector (OPS) have warned that the policy is elitist and may worsen inflation.

• Corruption and cash hoarding: Higher value notes make cash hoarding, money laundering, and off book transactions easier. That undermines the CBN’s long standing cashless economy push, which aims to boost traceability and reduce corruption. The OPS pointed out that at the current minimum wage of ₦70,000, a worker would receive just three ₦20,000 notes and one smaller bill if this policy were adopted, which is hardly equitable.

• Harm to the informal economy: The informal economy, where cash remains dominant, would suffer. Many small scale traders operate in low ticket environments; for them, bigger bills do not solve the issue of shrinking real incomes. Instead, they risk being forced to deal in change or revert to informal barter.

• Weak monetary context: Nigeria’s inflation remains high, the naira is depreciating, and public confidence in the currency is fragile. Introducing higher denomination notes without complementary reforms could worsen devaluation expectations and reduce trust in the monetary system.

Real world context and examples

When the ₦1,000 note was first introduced in 2005, it was worth about US$7 at the official rate; now it is worth less than 60 US cents. A kilogram of imported rice that cost around ₦150 then now sells for over ₦2,500. That reflects a massive loss in purchasing power, but printing bigger notes does not cure that loss, it only masks it.

Globally, some countries have introduced high denomination notes during inflationary periods, but the trend in most economies has been towards digital payments, cash reduction, and currency redenomination rather than creating bigger bills. Nigeria itself has invested in a cashless policy since 2011, aiming to shift the economy away from bulky cash transactions.

What should be done instead

Rather than issuing ₦10,000 and ₦20,000 notes, the government and CBN should prioritize:

• Strengthening digital payments infrastructure so cash becomes less necessary, especially in the informal and rural sectors.

• Tackling inflation by improving productivity, stabilising input costs, and fixing supply chains since high denominations cannot substitute for real value restoration.

• Enhancing financial inclusion and literacy so that small businesses and individuals feel comfortable moving away from cash.

• Considering a redenomination only when inflation and currency stability improve, not as a convenience measure.

• Enforcing anti money laundering safeguards to prevent illicit flows if any changes in currency denomination are ever made.

The idea of issuing ₦10,000 and ₦20,000 notes may appeal on paper, as it would mean less cash to carry and lower printing costs, but in Nigeria’s current economic environment, it is more of a threat than a convenience. Issuing such high denominations when inflation is still raging, the currency is weak, and the informal economy depends on cash would be a misstep. For now, it should remain a no go area for policymakers, who ought instead to focus on strengthening monetary stability, digital payments, and inclusive economic growth.
