As someone who spent years inside the central banking system, leading inspections and building early-warning models in collaboration with the European Central Bank, I have seen firsthand how fragile public trust in financial institutions can be—and how difficult it is to restore once broken. One of the most promising tools emerging today for shoring up that trust and reinforcing financial stability in developing economies is the Central Bank Digital Currency, or CBDC.

From Abuja to Abu Dhabi, central banks are increasingly exploring the potential of digital legal tender. The motivation is not just to keep pace with innovation but to address longstanding structural challenges: limited financial inclusion, informal economies, and persistent liquidity and compliance gaps in the banking system. In this article, I would like to examine the stability benefits of CBDCs, reflect on lessons from early adopters like Nigeria and Russia, and offer suggestions for MENA and Central Asian policymakers looking to deploy such systems effectively.

Transparency Is Stability

The first and most compelling argument in favor of CBDCs is the degree of visibility they offer central banks. In many emerging economies, the informal sector accounts for up to 30–50% of GDP. Transactions are difficult to trace, and monetary policy transmission is often distorted by parallel exchange rates, underbanked populations, and cash-based economies.

CBDCs provide an alternative: a state-backed, programmable currency that operates on a secure digital ledger. Unlike cash, every CBDC transaction can be monitored within appropriate privacy frameworks. For supervisors like myself, this is a breakthrough. It allows regulators to map liquidity flows, monitor systemic risks in real time, and respond with more precise monetary tools. This isn’t just about transparency—it’s about stability.

For instance, by observing CBDC usage trends, a central bank can detect unusual patterns that signal capital flight, sudden contraction in lending, or sector-specific stress. It can then respond with targeted support or macroprudential policy adjustments. In my own work developing stress testing models, such real-time data would have made our forecasting much more responsive to actual behavior.

Case Study: Nigeria’s eNaira

Nigeria became the first African country to launch a retail CBDC, the eNaira, in October 2021. The launch wasn’t perfect—adoption was slow at first—but it gave policymakers new insight into user behavior and highlighted operational challenges such as wallet interoperability and merchant onboarding.

More importantly, the eNaira served a macroeconomic function: it offered a controlled, traceable alternative to both cash and cryptocurrency at a time when inflationary pressures and Naira devaluation were destabilizing the local economy. By 2023, the Central Bank of Nigeria had begun using eNaira for social disbursements and public sector salary payments—tapping into the CBDC’s potential for policy targeting.

Kazakhstan and Tajikistan, where I’ve done most of my work, share similar economic contours with Nigeria: large unbanked populations, high remittance dependency, and a legacy of cash-dominant transactions. A digital currency pilot, structured with strong user incentives and layered privacy protection, could yield both inclusion and stabilization.

Lessons from the Digital Ruble

Russia, facing restricted access to global payment systems, launched a pilot version of the Digital Ruble to bolster financial sovereignty. The focus here is not just economic—but geopolitical. By offering an alternative payment architecture that is both domestic and digitally programmable, the Central Bank of Russia aims to insulate key financial flows from external shocks.

This offers an important lesson for countries in the MENA region, many of whom conduct large volumes of cross-border trade and are exposed to global monetary conditions beyond their control. A regionally interoperable CBDC infrastructure—designed to integrate with payment platforms across the GCC and North Africa—could lower transaction costs, accelerate settlement times, and build resilience into trade financing frameworks.

Implementation Cautions and Policy Recommendations

Despite their promise, CBDCs are not a silver bullet. Poor design or rapid rollout can lead to unintended consequences, including disintermediation of commercial banks, cybersecurity risks, or reduced trust in the currency itself. To prevent this, I recommend central banks in the MENA and Central Asian regions consider the following:

First, adopt a dual-tier distribution model. Central banks should issue the digital currency but allow commercial banks and licensed fintech firms to manage wallets and customer interfaces. This prevents disintermediation and leverages the existing financial infrastructure.

Second, prioritize financial literacy and digital access. CBDCs will only succeed if the public understands their benefits and has the tools to use them. This is particularly important in rural areas and among older populations.
Third, build interoperability with existing payment rails, including remittance corridors and QR code ecosystems. A CBDC that cannot integrate with current fintech platforms will struggle to scale.

Finally, start with use cases that offer visible, immediate value—such as government-to-person transfers, tax refunds, or cross-border B2B payments. These applications generate public confidence and validate the system’s relevance.

The Road Ahead

The introduction of CBDCs will not eliminate risk in financial systems. But if implemented responsibly, they can help central banks reclaim a greater degree of control, improve the precision of monetary tools, and build a foundation of trust between the state, its institutions, and the people they serve.

My own career—spanning bank supervision, financial inspection, and policy modeling—has taught me that trust is both fragile and powerful. CBDCs, properly designed, are a way to restore and sustain that trust in an era of digital acceleration.

For policymakers in the MENA region, the moment is ripe to explore CBDCs not just as a technology upgrade, but as a strategic instrument of financial stability.
