Nigeria faces a growing challenge as the amount of cash circulating outside the formal banking system continues to swell, reaching an unprecedented N5.4 trillion by the end of 2025. This significant figure underscores a persistent preference for cash transactions amongst Nigerians, despite ongoing efforts to promote digital payment adoption.

Data reveals that a staggering 94% of all cash in circulation resides outside the vaults of commercial banks. This trend presents a multitude of challenges for the Central Bank of Nigeria (CBN), hindering its ability to effectively manage monetary policy and control inflation.

The high volume of cash outside banks also contributes to reduced transparency and increases the risk of illicit financial activities. With a significant portion of economic activity occurring outside the formal financial system, tracking transactions and combating money laundering become significantly more difficult.

Several factors contribute to this persistent reliance on cash. These include a lack of access to banking services in rural areas, a preference for anonymity in transactions, and distrust in the formal financial system. While mobile money and other digital payment solutions have gained traction in recent years, they have yet to fully displace cash as the preferred mode of payment for many Nigerians.

In response to this concerning trend, sources indicate that the CBN is actively exploring new strategies to encourage greater participation in the formal banking system. One potential measure under consideration involves adjusting ATM card ratios. While details remain scarce, this could potentially involve incentivizing banks to issue more ATM cards or implementing policies to encourage greater usage of existing cards.

The specifics of the CBN's proposed ATM card ratio strategy remain unclear. However, the initiative reflects a growing concern within the central bank about the implications of such high levels of cash circulating outside the banking system. Experts suggest that a multi-pronged approach is necessary to effectively address the issue, including financial literacy campaigns, improved infrastructure for digital payments, and efforts to build trust in the banking system.

Ultimately, reducing the reliance on cash and promoting greater financial inclusion are crucial for fostering sustainable economic growth and stability in Nigeria. It remains to be seen whether the CBN's proposed ATM card ratio strategy, alongside other initiatives, will prove effective in curbing the tide of cash outside banks and promoting a more digitized and transparent financial system for the nation.
