Stablecoin

A cryptocurrency designed to hold a steady value, usually pegged to the US dollar (e.g. USDT, USDC).

A stablecoin is a type of cryptocurrency designed to minimise price volatility, unlike other digital assets that can experience significant swings. Its value is typically pegged, or "stabilised," against a traditional fiat currency like the US dollar, a commodity such as gold, or even a basket of assets. This makes stablecoins a digital representation of more stable, real-world assets, offering a bridge between the highly volatile crypto market and conventional financial systems.

How it works

Stablecoins achieve their price stability through various mechanisms. The most common type is fiat-backed, where each stablecoin issued is theoretically backed by an equivalent reserve of fiat currency held in a bank account. For example, a stablecoin pegged to the US dollar would aim to maintain a 1:1 ratio, meaning one stablecoin always equals one US dollar. These reserves are often audited to ensure transparency and trust in the stablecoin's peg. Popular examples include Tether (USDT) and USD Coin (USDC), which hold substantial reserves in commercial paper, treasury bills, and cash to back their tokens.

Other types of stablecoins exist, such as commodity-backed stablecoins (e.g., gold-backed tokens) and algorithmic stablecoins. Algorithmic stablecoins attempt to maintain their peg through smart contracts and financial engineering, automatically adjusting supply and demand without direct fiat reserves. However, historically, algorithmic stablecoins have proven more susceptible to de-pegging events during periods of high market stress, leading to a preference for fiat-backed options among many users due to their perceived reliability.

Why it matters for Australian investors

For Australian investors, stablecoins offer a practical way to participate in the crypto market without constantly converting back to Australian Dollars (AUD), which can incur fees and delays. They provide a safe haven during periods of market downturns, allowing investors to move out of volatile cryptocurrencies like Bitcoin or Ethereum into a stable asset without fully exiting the crypto ecosystem. This makes them ideal for short-term trading strategies, as a medium of exchange for decentralised finance (DeFi) applications, or for simply holding value without the risk of significant price fluctuations. While some stablecoins are attempting to peg to the AUD, the US dollar-pegged options remain the most prevalent and liquid on global and Australian exchanges.

Common questions

Q: Are stablecoins truly "stable"?

A: While stablecoins aim for stability, they are not entirely risk-free. Fiat-backed stablecoins rely on the issuer maintaining sufficient reserves and the integrity of their banking partners. Algorithmic stablecoins have a higher risk of losing their peg. Investors should research individual stablecoins and their backing mechanisms.

Q: Can I earn interest on stablecoins?

A: Yes, many decentralised finance (DeFi) platforms and centralised crypto exchanges offer opportunities to earn yield or interest on stablecoin holdings through lending, staking, or liquidity provision. However, these activities come with their own set of risks, including smart contract vulnerabilities or platform insolvency.

Q: How do stablecoins relate to ATO and CGT in Australia?

A: In Australia, the Australian Taxation Office (ATO) generally views stablecoins as a type of cryptocurrency. While holding a stablecoin itself might not trigger a capital gains tax (CGT) event if its value remains stable against the AUD, converting other cryptocurrencies into a stablecoin (and vice-versa) is typically considered a disposal for CGT purposes. It's crucial for Australian investors to keep detailed records of all stablecoin transactions for tax reporting.
