What are Stablecoins and Why do They Matter?

Over the past few years, stablecoins have grown from a niche tool into a mainstream part of global finance. With fast settlement times, low fees, and 24/7 availability, they now power billions of dollars in cross-border payments every day, without the volatility typically associated with crypto assets. But what exactly are stablecoins, and why are businesses and institutions now embracing them?

What is a Stablecoin?

A stablecoin is a type of digital asset whose value is pegged to another asset, most commonly a fiat currency like the US dollar. While they operate on blockchain networks, stablecoins are fundamentally different from speculative cryptocurrencies like Bitcoin or Ethereum. They’re designed to maintain a consistent value over time and are typically backed 1:1 by reserves held in cash or short-term U.S. Treasuries. This stability makes them far more practical for payments, settlements, and treasury operations.

Some of the most widely used stablecoins are USDC (from Circle) and USDT (from Tether). These can be seen as digitised or programmable dollars (crucially – not the same as a CBDC), capable of moving globally and settling around the clock without relying on banking hours or cross-border wires.

There are also other types of stablecoins, such as:

• Commodity-backed options like Paxos Gold (PAXG), which is pegged to the price of gold.
• Algorithmic stablecoins, which aim to maintain value through smart contract-based supply rules (though these are more experimental and less widely adopted). 

Why Stablecoins Are Gaining Ground

Institutional adoption of stablecoins is increasing, particularly for international payments and treasury operations. There are four main reasons for this, namely:

• Transactions are quick and often finalised in just minutes
• Costs are lower, since there are no intermediaries or wire fees 
• Transfers are borderless - you can send funds from New York to Lagos or Manila just as easily as you can across town
• Every transaction is logged on-chain or via a platform interface such as SettlementX, improving trust and transparency. 

Are Stablecoins Regulated? 

Increasingly yes, and regulatory momentum is growing quickly. In Europe, the Markets in Crypto-Assets (MiCA) framework now offers a comprehensive standard for stablecoin issuers, requiring them to maintain full reserves, submit to regular audits, and operate under a clear licensing regime. The focus is on transparency, consumer protection, and ensuring that stablecoins can function safely within the broader financial system.

In the U.S., the proposed Stablecoin Transparency Act would require issuers to hold fiat reserves on a 1:1 basis and undergo regular third-party audits. While it’s not yet enacted, the legislation signals a strong intent to formalise the role of stablecoins in regulated finance.

That said, not all stablecoins are subject to the same standards. USDT (Tether) remains the most widely used by volume, particularly in trading and emerging markets, but it has faced scrutiny in the past over its reserve disclosures and regulatory posture. By contrast, USDC (issued by Circle) and USDP (issued by Paxos) are more commonly adopted for business and institutional use. Both are issued by regulated U.S. financial entities, fully backed by cash and short-term government securities, and publish regular attestations from independent auditing firms. These structures have made them the preferred choice for organisations that prioritise transparency and compliance.

The Bottom Line 

Today, stablecoins sit comfortably at the intersection of digital infrastructure and real-world utility. Whether you’re settling platform revenue, managing vendor payouts, or building a new financial product, stablecoins offer a better way to move money.
