How the naira redesign disrupted Kano's informal markets

When the Central Bank of Nigeria announced in October 2022 that redesigned 200, 500 and 1000 naira notes would replace the existing currency, the policy was sold as a sweeping financial clean-up. Officials argued that the old notes had become tools for hoarding, election rigging and illicit cash movements. By forcing citizens to swap their holdings, the bank hoped to expand the formal banking sector and reduce the volume of money circulating outside regulated channels.

In Kano, a state of roughly sixteen million people and home to some of West Africa's oldest trading networks, the announcement landed in a society where cash is not simply convenient but structural. Petty traders at Sabon Gari, wholesalers at Kantin Kwari, and bead and textile merchants around Kurmi Market operate almost entirely on physical notes. For them, a naira is not a digital figure on a screen; it is the thread that holds the day's commerce together.

Australian readers who frequent weekend stalls at Paddy Markets in Sydney's Chinatown or browse the Sunday arts market at The Rocks will recognise a similar reliance on small cash transactions, even as the broader Australian economy trends toward tap-and-go. The contrast is instructive: a country where cash is shrinking but still common, and a Nigerian city where cash remains the lifeblood of the street.

The redesign was meant to push informal actors toward banks. Instead, in Kano and across much of northern Nigeria, it produced weeks of queues at ATMs, angry confrontations at filling stations and an almost complete evaporation of small change. The consequences for the informal economy were immediate, severe and, in many cases, still being measured years later.

The policy's stated aims and initial rollout

Godwin Emefiele, then governor of the Central Bank of Nigeria, framed the redesign as a weapon against currency hoarding and a way to deepen financial inclusion. The argument was that large sums sitting in private vaults, often outside the banking system, fuelled inflation and gave bad actors a way to move untraceable money. The new notes were also pitched as more secure, with features intended to deter counterfeiting.

The original deadline gave Nigerians only a few weeks to exchange their old notes at banks. That window proved wildly insufficient in a country of more than two hundred million people, the majority of whom still rely on cash for daily transactions. The policy was also announced during a political season, when campaigning traditionally floods the economy with new naira notes.

For Kano, the timing coincided with the peak trading season that follows the rainy harvest, when grain, livestock and groundnut flows into the city are at their highest. Wholesalers who normally move funds by the millions of naira in a single afternoon suddenly found their usual channels jammed. Traders arrived from neighbouring states with bags of old notes that banks could no longer accept, creating a parallel scramble at bureau de change operators.

The Supreme Court eventually intervened in early 2023, ordering that the old notes remain legal tender while the matter was adjudicated. By then, the damage to commerce had already cascaded through the informal economy, with effects that stretched well beyond the courtroom's ruling.

Cash scarcity across Kano's markets

Inside Kano's markets, the new policy translated almost overnight into a near-total absence of small denominations. Traders who once received crisp 200 naira notes from customers suddenly had no change to give. Many small buyers were turned away or asked to buy extra goods just to round up to the next available note.

At Kantin Kwari, the sprawling fabric and provisions market near the old city, vendors described days where sales fell by more than half because shoppers could not present the right notes. Similar scenes played out at Sabon Gari, known for its motorcycle and spare parts trade, where mechanics and dealers depend on quick cash settlements to keep their workshops running.

The experience offers a striking parallel to small businesses in Melbourne's laneway cafes or Brisbane's suburban bakeries, where Australia's move toward cashless payments has forced proprietors to recalibrate. Australians adapted with relative ease because the supporting infrastructure, from eftpos terminals to widespread smartphone banking, was already in place. In Kano, the equivalent infrastructure was patchy, expensive and, for many traders, entirely foreign.

Pressure on small traders and daily commerce

The human cost of the redesign fell heaviest on those operating at the margins. Market women selling pepper, dried fish and local sweets reported losing income on days when customers simply stayed home. Transport operators, who rely on fares of fifty or one hundred naira to keep their motorbikes running, watched their daily takings evaporate into long searches for working ATMs.

In Kano's tea stalls, owners resorted to keeping handwritten ledgers, allowing regulars to run up tabs that would be settled later. The informal credit systems that emerged were a creative workaround, but they also exposed families to debt and strained the social ties that typically underpin small-scale commerce. Some traders reportedly travelled hours to deposit cash in banks outside the state, only to find branches either closed or unable to dispense enough new notes.

The macroeconomic backdrop intensified these strains. Rising inflation, partly fuelled by the policy itself, eroded the value of any naira a trader managed to acquire. An analysis of Nigeria's debt servicing costs highlights how interest payments now consume a large share of federal revenue, leaving limited fiscal space to cushion shocks like the cash crunch. With little relief from Abuja, Kano's informal economy absorbed the blow largely on its own.

A push toward digital payments and new habits

Amid the disruption, an unintended consequence of the policy was a sudden expansion in the use of point-of-sale terminals and mobile transfers in Kano. Before the redesign, POS operators were a modest presence on the streets. During the cash shortage, they became essential, charging fees of one hundred naira or more for a withdrawal that customers desperately needed.

Bank branches in the city extended their hours, and several fintech firms reported a sharp rise in new account registrations from traders who had previously managed their entire economic life in cash. Surveys conducted by local chambers of commerce a year after the crisis suggested that a meaningful share of small businesses had retained at least one digital channel for receiving payments.

Australia's experience with cashless transitions, including the Reserve Bank of Australia's gradual phasing out of large denomination notes and the popularity of buy-now-pay-later schemes among consumers in Adelaide and Perth, shows how quickly digital habits can harden once they are forced. The Nigerian shift was more abrupt and less evenly distributed, but the direction of travel was similar.

Lingering effects and questions for the future

Years after the policy, Kano's informal economy has largely recovered in volume, but the structure of that recovery remains uneven. Many traders who adopted digital tools during the crisis have continued to use them, particularly younger operators and those with regular wholesale customers. Older market women, however, often returned to cash once notes were available again, citing mistrust of mobile apps and the unreliability of network coverage in busy market lanes.

The episode also sharpened public debate about who bears the cost of monetary reform. Critics argue that the central bank's approach placed an unfair burden on people who operate outside the formal economy by choice or necessity. Supporters counter that the informal sector's size makes Nigeria's broader financial stability impossible to secure without bringing more cash into regulated channels.

For Australians watching from cities like Sydney or Hobart, where regulatory frameworks around payments and consumer protection are set by bodies such as the Australian Securities and Investments Commission, the Kano story offers a reminder of how political and logistical factors shape monetary policy on the ground. Reforms that look clean on a central bank balance sheet can look very different in a market stall.

Recommendations for resilient cash systems

The episode in Kano stands as a case study in how monetary policy, however well-intentioned, can ripple outward in ways that central bankers do not always anticipate. The city's markets have shown a stubborn capacity to absorb shocks, but the cost of that resilience is borne by traders, drivers and families who have the least buffer against sudden disruption. As Nigeria's central bank weighs future reforms, the voices from Kantin Kwari and Sabon Gari deserve a place at the table.
