The digital dollar trap: Why African currency-backed stablecoins like cNGN won’t stand a chance in a USD-pegged world – except

The promise of blockchain was radical decentralisation of the global financial order. For emerging markets, the narrative was particularly seductive: a digital exit ramp from the US dollar’s hegemony. But as we approach the end of the first half of 2026, the data tells a much more ironic story. Instead of breaking the greenback’s hold, stablecoins have aided blockchain in becoming the ultimate engine of dollarisation.

According to the latest supply data from Artemis, the picture is grim, as the global market share of non-USD stablecoins (euro, Canadian dollar, Japanese yen, Singapore dollar, Nigerian cNGN and others) has fallen to just 0.24%, even as their supply has jumped 195% in the last five years. While the total stablecoin market capitalisation has surged above $317 billion since its creation in 2014, the vast majority of that value remains tethered to the US dollar. That’s not the promised multipolar monetary world, but the dollar consolidating its power with unprecedented efficiency.

For African nations like Nigeria, the launch of projects such as the cNGN, the compliant stablecoin for the naira, represents a noble effort to modernise local payment. However, it also highlights what might be termed the ‘sovereignty trap’. Central banks across the continent are attempting to digitise local currencies at a time when the market is voting with its feet in the opposite direction.

In a region where inflation is a persistent shadow and local currencies frequently lose double-digit value against the dollar, a stable version of a weak currency is often an asset nobody asked for. Qualitative sentiment across the continent suggests that up to 95% of active digital asset users would prefer to be paid in digital dollars (USDT or USDC) rather than their own depreciating fiat. The issue is not one of technology, but of trust and purchasing power. When the core problem is the underlying currency’s volatility, digitising that volatility via a stablecoin does not solve the fundamental economic challenges; it merely masked it.

The Liquidity Gap

The liquidity disparity between the dollar-denominated world and local-currency stablecoins is now an ocean. As of early 2026, on-chain tokenised Real-World Assets (RWAs), primarily US Treasuries, have surpassed $26 billion in total value. Specifically, tokenised US Treasuries account for over $15.4 billion of this, providing a high-yield, high-security bedrock for global digital liquidity.

Contrast this with the ghost-town liquidity of non-USD pairs. For a local currency stablecoin to function as a tool for global trade, it must have deep liquidity pools that allow for seamless conversion into other major currencies without massive slippage. Currently, those pools do not exist for the cNGN or its peers. Without this depth, these tokens are economically non-viable for inter-African trade. They remain stranded assets on a digital island, unable to compete with the gravity of the dollar-denominated ecosystem.

Why local stablecoins like cNGN should pivot to a regional utility

That is not to say the work being done by the African Stablecoin Consortium and other regional innovators is without merit. On the contrary, their value lies not in global competition but in domestic transformation. The critical error is framing these tokens as challengers to the dollar’s global dominance. Instead, they should be positioned as localised utility tokens.

The true utility of the cNGN is its ability to bypass broken domestic banking rails. In many African markets, the cost and friction of moving money within the country, let alone across borders, remain prohibitively high. A local stablecoin can lower the cost of remittances, facilitate real-time settlement for SMEs, and provide the technological infrastructure for a modern digital economy. By focusing on the last mile of domestic and regional payments, these projects can succeed where global ambitions would fail.

The African Continental Free Trade Area (AfCFTA) and its Digital Trade Protocol provide a perfect theatre for this pivot. Rather than trying to make the Naira a global reserve currency, the goal should be to use the cNGN as a compliant bridge for intra-African trade. If a merchant in Lagos can pay a supplier in Accra using a digital Naira-to-Cedi bridge that settles instantly and cheaply, the mission is accomplished.

This approach acknowledges the reality that the market has already chosen the Greenback for global savings and large-scale settlement. By accepting this, African central banks can stop chasing the ghost of global currency status and start building tools that actually help their citizens at home.

In the end, the cNGN and its peers may never be global giants, and they don’t have to be. Their success will be measured by their ability to grease the wheels of local commerce and provide a secure, regulated entry point into the wider digital economy. Without this shift in perspective, these projects risk becoming expensive digital vanities, technological monuments to a sovereignty that the market no longer respects in its fiat form.

The blockchain has indeed promised a new world, but it is one where the dollar remains the undisputed king of the hill. African innovators who recognise this digital dollar trap and build around it will be the ones who truly deliver value. Those who continue to misread the room may find themselves with a perfect digital representation of a currency the world has already moved past.
