South Africa’s stablecoin market is giving policymakers a closer look at how digital currencies can affect emerging economies. The experience comes as stablecoins move beyond crypto trading and become part of cross-border payments, settlement, and digital finance.
The International Monetary Fund (IMF) has warned that stablecoins can improve payment efficiency while creating new risks for monetary policy and capital flows. Its recent analysis shows why emerging markets need to understand how people use stablecoins before deciding how to regulate them. South Africa offers a useful case.
The country has a developed financial system, an active crypto market, and a growing regulatory framework. Yet, local stablecoin activity remains concentrated in US dollar-pegged assets. That creates an important lesson for other emerging markets considering local-currency stablecoins.
South Africa’s Stablecoin Market Is Growing
Stablecoins already account for most transactional activity on South African crypto exchanges. The South African Reserve Bank (SARB) says the activity mainly involves trading, arbitrage, and settlement within crypto markets. Users also employ stablecoins for cross-border transfers and remittances.
However, payment use for everyday goods and services remains limited. Most activity involves US dollar-pegged stablecoins rather than rand-based alternatives. The SARB’s June 2026 Financial Stability Review provides more context. It says 310 Crypto Asset Service Providers (CASPs) held licences from the Financial Sector Conduct Authority (FSCA) at the end of March 2026.
The review also found strong domestic activity in Tether. On-chain transactions involving Tether across Luno, VALR and AltCoinTrader reached almost R27 billion in the year to April 30, 2026. That activity does not mean stablecoins currently pose a systemic risk to South Africa. The SARB says crypto activity remains too small for that. However, the central bank continues to monitor the sector because stablecoin activity is growing and cross-border links are becoming stronger.
The Dollar Stablecoin Challenge
One of the clearest lessons from South Africa is the strength of dollar-backed stablecoins. People can use USDT and USDC to gain digital exposure to the US dollar. This can make them attractive in markets where users want access to foreign currency or faster international transfers.
The IMF has warned that this trend can create what it calls digital dollarisation. In countries with volatile currencies or weak macroeconomic conditions, people may shift part of their savings and transactions away from local money and toward dollar stablecoins. That creates a difficult policy question.
A stablecoin can make payments faster and cheaper. At the same time, widespread use of a foreign-currency stablecoin can reduce demand for local money. It can also make capital flows harder to monitor. The IMF says stablecoins can increase de facto capital mobility. This can make existing capital-flow management measures harder to enforce.
Local Stablecoins Face a Difficult Test
South Africa has also explored whether rand-pegged stablecoins could play a role in the domestic financial system. The Intergovernmental Fintech Working Group (IFWG) published a landscape diagnostic on rand-pegged stablecoins in March 2025. The group then released a discussion paper on rand-pegged stablecoin arrangements for public consultation in March 2026. The aim is not simply to create a digital version of the rand.
Policymakers must consider how such tokens would work alongside banks, payment systems, crypto platforms, and existing financial regulations. They must also assess how local stablecoins would interact with foreign-currency stablecoins. This is where South Africa’s experience becomes relevant to other emerging markets.
A local stablecoin may support domestic payments. However, users may still prefer US dollar stablecoins if they offer deeper liquidity, wider acceptance, and easier access to global markets.
Why Network Effects Matter
Stablecoins compete on more than their currency peg. Users also care about liquidity, exchanges, wallets, payment providers, merchant acceptance, and access to other digital assets. The more people use a stablecoin, the more useful it can become. This creates a strong advantage for established dollar stablecoins.
A new rand, naira, or shilling stablecoin must therefore compete with an existing global network. The challenge is even greater when users already want digital access to dollars. The IMF’s analysis of Nigeria shows a similar problem. Nigeria launched the regulated cNGN, a naira-backed stablecoin, in early 2025. Yet adoption remained very small in its early stages.
The IMF reported that about 66 million cNGN, worth roughly $44,000, had been issued and held across around 20 digital wallets. Only 74 on-chain transactions had taken place at the time of the IMF’s assessment. The Nigerian case does not prove that local stablecoins cannot succeed. It does show how difficult it can be to compete with established dollar stablecoins.
Stablecoins Can Improve Cross-Border Payments
The benefits remain significant. Stablecoins can move value across borders without relying entirely on traditional correspondent banking networks. They can also settle transactions at any time and support programmable payments.
The SARB recognises this potential. Its National Payment System Vision 2030+ consultation paper says stablecoins could enable fast, low-cost transfers without multiple intermediaries. It also notes that they could support automated transactions and new forms of digital commerce. The IMF has reached a similar conclusion.Its research says stablecoins can improve payment efficiency and support financial innovation. Another IMF study found that markets expect stablecoins to increase competition in payments, particularly in cross-border services.
For emerging markets, this could address real problems.International payments can be expensive and slow. Small businesses can also struggle to access foreign currency and reliable payment channels. Stablecoins may offer another route when traditional systems create too much friction.
But Faster Payments Create New Risks
The payment benefits do not remove the risks. The IMF says stablecoins can create problems for monetary sovereignty, financial stability, and capital-flow management. These risks become more important when foreign-currency stablecoins gain widespread use. There are also risks around the stablecoins themselves.
A stablecoin needs reliable reserves and a credible redemption mechanism. If users lose confidence in the issuer, they may rush to redeem or sell their tokens. The IMF’s April 2026 working paper argues that stablecoins can face run risks. It says strong reserve requirements can reduce those risks, although they may also affect the profitability of issuers. South Africa’s central bank has raised similar concerns.
Its financial stability analysis says foreign-issued, dollar-pegged stablecoins present greater risks than bank-issued or fully backed domestic alternatives. The SARB also highlights concerns around regulatory gaps and the possibility of a stablecoin run affecting the wider financial system.
Regulation Must Cover the Full Payment Chain
Another lesson is that regulators cannot focus only on stablecoin issuers. The wider ecosystem includes exchanges, wallets, payment providers, on-ramps, off-ramps, and blockchain networks. Regulators need enough information to understand how money moves through these channels.
The IMF has stressed the importance of data.Without information about who holds stablecoins, how much they hold, and why they use them, authorities may struggle to measure risks or respond effectively. This challenge becomes harder when users move funds through self-custody wallets and offshore platforms. South Africa is already building a more detailed regulatory framework.
The country has licensed hundreds of CASPs through the FSCA. At the same time, the SARB and other regulators continue to examine stablecoins and their effect on financial stability. That approach offers an important lesson for other emerging markets. Regulation needs to evolve with the technology instead of focusing only on one type of provider.
The Policy Balance Emerging Markets Need
The IMF’s broader message is not that emerging markets should ban stablecoins.Instead, policymakers need to balance their benefits with their risks. The first step is to understand why people use them. If users choose stablecoins because domestic payments are slow or expensive, improving local payment systems may reduce the pressure.
If users choose dollar stablecoins because they want protection from currency instability, the issue becomes more complex. In that case, stablecoin adoption can reveal deeper problems in the domestic financial system. Better monetary policy, stronger institutions, and more reliable payment infrastructure may matter as much as crypto regulation.
The IMF argues that strong macroeconomic fundamentals can reduce demand for foreign-currency stablecoins. However, it also warns that network effects can keep currency substitution in place even after economic conditions improve.
South Africa’s Experience Offers a Wider Lesson
South Africa’s experience shows that stablecoin adoption does not happen in isolation. Users choose assets based on liquidity, currency preferences, payment needs, and access to global markets. A local stablecoin must compete with established alternatives on all of these factors.
At the same time, stablecoins can become useful payment infrastructure when regulators provide clear rules and businesses build practical applications around them. This creates a difficult policy balance. Restrictive rules could push activity toward less visible channels. Weak rules could leave users and the financial system exposed to unnecessary risks. A risk-based framework may offer a better middle ground.

Editorial Takeaway
South Africa’s stablecoin experience offers emerging markets a useful warning and an opportunity. Stablecoins can make payments faster and improve access to digital financial services. However, dollar-backed tokens can also increase currency substitution and make capital flows harder to monitor.
The lesson for emerging markets is therefore not to choose between innovation and regulation. It is to build both at the same time. Countries that understand why users adopt stablecoins will be better positioned to design rules that support useful payment innovation without weakening monetary stability. South Africa’s ongoing approach to stablecoins shows why that balance will become increasingly important as digital money moves further into mainstream finance.
