Stablecoins are no longer a peripheral issue for South Africa’s financial system.
The South African Reserve Bank (SARB) has acknowledged that stablecoins account for the bulk of transactional activity on South African crypto exchanges. On-chain transactions involving Tether across Luno, VALR and AltCoinTrader reached almost R27 billion in the year to 30 April 2026.
But there is an important qualification: SARB says this activity is still largely connected to trading, arbitrage and settlement within crypto markets, rather than the purchase of everyday goods and services. Stablecoins are also being used, to a lesser extent, for cross-border transfers and remittances.
So why is SARB paying such close attention?
Because the question is no longer simply whether stablecoins are growing; it is what stablecoins are becoming.
A crypto asset, a payment instrument or digital money?
A stablecoin is designed to maintain a relatively stable value, usually by being pegged to a monetary unit such as the US dollar or rand and supported by reserve assets.
That gives stablecoins characteristics that distinguish them from many other crypto assets.
They can be used to transfer value, settle transactions and, in some cases, be redeemed for fiat currency at face value.
SARB and the Intergovernmental Fintech Working Group (IFWG) have recognised that these characteristics give stablecoins the potential to function as payment instruments. The authorities are therefore examining the use cases for stablecoins and considering what regulatory response would be appropriate.
This creates an interesting regulatory problem.
If a digital asset is primarily being traded as an investment, the regulatory questions look one way.
If that same type of asset starts being used to transfer value, settle transactions or make payments, a different set of questions arises.
And if it begins to perform functions that resemble money, the implications become even broader.
That is the point at which stablecoin regulation stops being only a crypto question.
It becomes a payments, monetary policy and financial stability question.
South Africa has already drawn an important line
In May 2026, SARB and National Treasury issued a joint communication clarifying the treatment of crypto assets used for domestic payment purposes.
The communication confirms that crypto assets do not currently fall within the National Payment System Act simply because they are used for payment purposes. Crypto assets are not regarded as money or funds under the Act and do not have legal tender status.
But that does not mean stablecoin payment activity sits outside regulatory consideration.
In fact, the same communication specifically addresses stablecoins.
It notes that stablecoins can have characteristics of digital money and could potentially be adopted as payment instruments. The IFWG is analysing the use cases for rand-pegged stablecoins to inform an appropriate policy and regulatory response.
South Africa is not simply deciding whether stablecoins are “regulated” or “unregulated”.
The more difficult question is which regulatory framework should apply to which stablecoin activity.
The rand stablecoin question
This is where things get particularly interesting for South Africa.
Not all stablecoins raise the same policy questions.
A stablecoin pegged to the rand is fundamentally different from one pegged to the US dollar when considered from the perspective of South Africa's monetary system.
SARB has expressly highlighted the risk that foreign-currency-pegged stablecoins could contribute to currency substitution, or “dollarisation”, if they became widely used for domestic transactions.
The May communication therefore states that SARB is unlikely to consider foreign-currency-pegged stablecoins as payment instruments for domestic transactions. At the same time, SARB is interested in testing rand-pegged stablecoin payment use cases through the IFWG Regulatory Sandbox.
The market data shows why this distinction matters.
Despite the regulatory and policy interest in rand-pegged stablecoins, their circulation remains relatively small. SARB reported that the total value of rand-pegged stablecoins in circulation was R176 million at the end of January 2026.
By contrast, the dominant stablecoin activity in South Africa is centred on US dollar-pegged assets.
That creates a particularly South African regulatory tension: The stablecoins people are actually using most are not necessarily the stablecoins that best align with the domestic monetary system.
What is SARB actually concerned about?
SARB Deputy Governor Rashad Cassim recently put the issue quite clearly.
The question is not simply whether stablecoins are growing. It is what is driving that growth and what stablecoins are actually being used for:
- Are they providing a more efficient payment instrument?
- Are they functioning as blockchain-based electronic money?
- Or are they becoming an alternative to publicly issued money?
The further stablecoins move towards the latter, the more significant the regulatory concerns become.
SARB has identified a number of issues that require consideration, including:
- consumer and prudential safeguards;
- the quality and transparency of assets backing stablecoins;
- monetary stability;
- currency substitution; and
- the potential circumvention of domestic and cross-border financial channels.
These are not theoretical concerns.
A stablecoin can move value quickly, across jurisdictions and outside traditional payment rails.
That can be a feature when the objective is cheaper, faster and more accessible payments.
It can also create regulatory challenges if the technology is being used to bypass existing controls rather than improve the underlying financial system.
Is regulation the problem, or is the financial system?
This may be the most interesting question emerging from SARB's current approach.
Cassim has framed the policy issue in terms of why stablecoins are gaining ground.
If they are growing because existing payment systems are too expensive, slow or difficult to access, then the appropriate regulatory response may not be to restrict the technology.
It may be to make the existing financial system work better.
If, however, stablecoins are gaining ground because they provide a way around domestic or cross-border financial channels, the regulatory concern becomes much more significant.
That distinction is important for businesses building stablecoin-based products. A business may believe that it is simply offering a faster settlement mechanism.
From a regulator's perspective, the question may be very different: What economic function is the product actually performing?
That is increasingly likely to matter more than the technology being used to deliver it.
Where does this leave businesses?
For businesses considering stablecoin infrastructure, the regulatory question should not begin and end with whether the underlying token is classified as a crypto asset.
The more useful questions are:
- What is the stablecoin being used for?
- Is it being held as an investment?
- Used for trading or settlement within crypto markets?
- Used to make domestic payments?
- Used to facilitate cross-border transfers?
- Or incorporated into a broader payments or financial product?
The answers could determine which regulatory considerations become relevant.
This is particularly important as South Africa develops its broader digital payments infrastructure.
SARB is actively modernising the country's payments system and considering how private digital instruments such as stablecoins fit into that future. It has also indicated that it is assessing whether existing regulatory frameworks can be extended to stablecoin arrangements or whether separate regulation is required.
What happens next?
For now, South Africa has not introduced a dedicated stablecoin regulatory regime.
Instead, regulators are building their understanding of how stablecoins are being used and where existing frameworks may or may not be sufficient.
The direction of travel is nevertheless becoming clearer.
Stablecoins are being considered not only as crypto assets, but as potential components of the future payments ecosystem.
That means their regulatory treatment will increasingly depend on function.
The same underlying technology could raise very different regulatory questions depending on whether it is being used for trading, settlement, domestic payments or cross-border value transfer.
And that brings us to the bigger question.
Stablecoins are already moving value.
The question South Africa now needs to answer is not simply whether they are crypto.
It is: What exactly are they becoming?
Because once a digital asset starts performing functions traditionally associated with money, the legal question changes.
And South Africa is now actively working out where that line should be drawn.
