Global payments underpin almost everything in the modern economy, but despite moving trillions of Dollars a day, the system still feels stuck in another era. Cross-border transfers can take days, rack up hefty fees, and only work during banking hours. Stablecoins are quietly changing that.

What started as a niche tool for crypto traders is shaping the next phase of financial infrastructure, one that’s beginning to challenge how money moves around the world.

From crypto workaround to financial plumbing

In the early days, stablecoins were mostly a way for traders to park value between volatile crypto positions. Today, they’re doing far more than that.

Transaction volumes have surged to the point where some stablecoin networks are processing activity comparable to major payment players. The appeal is simple. Blockchains can settle transactions 24/7 with finality that traditional banking systems struggle to match.

For institutions, it’s about upgrading the rails that move money, faster settlement, fewer intermediaries, and more control over how payments are executed.

Why stablecoins matter

Faster settlement

International payments through correspondent banks can take several business days. For companies operating across borders, especially in sectors like mining, energy, or agriculture, that delay creates real risk, from currency swings to tied-up working capital. Stablecoins remove much of that friction. Funds can move and settle almost instantly, allowing treasurers to manage liquidity and hedge exposure in real time.

Lower costs

Every hop in a traditional payment chain adds fees. In emerging markets, cross-border payments can pass through multiple banks, each adding to the total transfer costs. Stablecoins collapse that chain. By settling peer-to-peer on blockchain rails, they significantly reduce fees. 

Built-in automation

One of the less obvious benefits of stablecoins is programmability. Payments can be linked to conditions written into smart contracts – for example, releasing funds only once goods arrive or documents are verified. This kind of “atomic settlement” reduces the need for escrow, lowers counterparty risk, and cuts down on manual processes that slow everything down.

The move toward local currency stablecoins

Dollar-based stablecoins like USDC and USDT still dominate the market, but momentum is gaining in other localised stablecoin markets. Increasingly, countries and businesses want the efficiency of digital rails without defaulting to the US dollar.

Several trends are pushing this change.

Regional trade and currency sovereignty

More countries are looking to settle trade in local currencies to avoid conversion costs and Dollar exposure. Local currency stablecoins make that possible while retaining the speed and efficiency of blockchain settlement.

This is particularly relevant in regions like Southern Africa, where trade within blocs such as Southern African Development Community (SADC) could benefit from faster, cheaper local-currency settlement.

Clearer regulation

Stablecoin regulation has moved quickly in the past few years. Frameworks like Europe’s MiCA and new legislation in the US have brought clarity around reserves, compliance, and consumer protection.

That clarity has opened the door for institutionally-backed stablecoins that meet both regulatory standards and enterprise requirements.

Moving into the mainstream

Stablecoins are no longer confined to crypto wallets. Partnerships with payment processors are starting to bring stablecoin functionality into familiar checkout and point-of-sale environments, turning them into practical tools for everyday commerce.

ZARU and the South African use case

ZARU is a good example of how this next phase looks in practice. It’s a Rand-pegged stablecoin, fully backed by onshore reserves held with institutional custodians such as Standard Bank, and managed by Sanlam.

For South African businesses trading across the region, this matters. Settling in digital Rands, without routing payments through correspondent banks in, say, New York or London, can reduce costs, speed up settlement, and lower risk.

It’s not a theoretical improvement. It directly addresses pain points that companies have lived with for decades.

What this means for investors

Stablecoins aren’t about price charts or cycles. They’re infrastructure. The opportunity lies in adoption, integration, and trust, in how widely these systems are used, how transparent their reserves are, and how well they plug into existing financial networks.

As regulation matures and institutions continue to adopt digital settlement rails, stablecoins are increasingly looking like essential plumbing for modern finance, rather than a side project of the crypto world.
