Stablecoins have emerged as one of the most talked–about innovations in the crypto universe. They promise the best of both worlds: the speed and programmability of cryptocurrencies, combined with the price stability of traditional money.

Yet central banks – especially the Reserve Bank of India (RBI) – remain deeply sceptical about stablecoins & their role in a modern financial system.

In this post, we unpack what stablecoins are, why the RBI is pushing back so hard against them, and how other countries are responding. The goal is to help you understand whether these “stable” tokens really deserve a place in everyday finance.

What exactly are stablecoins?

Stablecoins are a category of crypto–assets designed to maintain a relatively stable value by being pegged to an underlying reference asset. That asset is usually a sovereign currency like the US dollar, but it can also be a basket of short–term securities or commodities.

Unlike Bitcoin or Ether, whose prices swing wildly based on market sentiment, stablecoins try to keep their value close to one unit of the asset they track.

This stability in Stablecoins is achieved through different design choices:

– Fiat–backed stablecoins hold reserves in bank deposits, government securities or money–market instruments, supposedly equal to the value of tokens in circulation.

– Crypto–collateralised stablecoins are backed by other crypto‑assets posted as collateral, often worth more than the stablecoins issued.

– Algorithmic stablecoins try to maintain their peg using code–based monetary rules instead of hard collateral – a model that has repeatedly failed in practice.

On the surface, this makes stablecoins look like a digital twin of cash – easy to store in a wallet, quick to transfer globally, and ideal for trading other crypto–assets. But regulators argue that beneath this convenient façade lies a complex set of risks.

Why the RBI is so skeptical about stablecoins

RBI Deputy Governor T. Rabi Sankar has been one of the strongest critics of stablecoins among major central bankers. His core argument is blunt: stablecoins do not add any meaningful value to India’s financial system and may actually undermine it.

From a money perspective, he points out that genuine money in a modern economy has two key features: it is fiat (backed by the state) and it preserves the “singleness” of money – one rupee means the same everywhere in the system.[web:3] Stablecoins, by contrast, are privately issued tokens with no sovereign guarantee, whose value ultimately depends on the credibility and risk management of the issuer.

India already offers one of the world’s most advanced and low–cost digital payment networks – UPI, RTGS, NEFT and IMPS. These rails allow instant transfers at near–zero cost for households and businesses, all in fully regulated bank money. Given this backdrop, the RBI’s view is that stablecoins do not solve any real payments problem in India. Instead, they import a new set of vulnerabilities into an otherwise efficient system.

The big risks: from rupee substitution to financial instability

So what exactly worries the RBI about stablecoins?

1. Currency substitution and loss of monetary sovereignty 

For an emerging market like India, the biggest fear is that foreign–currency stablecoins – especially dollar–backed ones – could start replacing the rupee in domestic payments and savings. If people and businesses begin preferring dollar stablecoins for everyday use, demand for rupees could erode over time, weakening the central bank’s grip on monetary policy.

This kind of “digital dollarisation” would make it harder for the RBI to manage inflation, interest rates and liquidity, because a growing share of financial activity would take place in a foreign–denominated private token that it neither issues nor controls.

2. Financial–stability risks and the danger of runs

Stablecoins also pose classic systemic risks. If users lose confidence in an issuer’s reserves, they may rush to redeem their tokens, forcing the issuer to liquidate assets quickly. That fire sale can transmit stress to money–market funds, short–term bond markets and even banks that hold similar assets.

The more widely a stablecoin is used for payments and savings, the more disruptive such a run could become for the broader financial system.[web:18] From the RBI’s standpoint, allowing large private players to issue money–like liabilities without bank–style regulation is a recipe for instability.

3. Regulatory arbitrage and harder capital–flow management

Cross–border use of stablecoins creates another headache. These tokens can be moved across jurisdictions in seconds, often through decentralised platforms that do not follow traditional know–your–customer (KYC) or anti–money–laundering (AML) rules.

If residents start using stablecoins to bypass capital controls or reporting norms, it becomes much harder for authorities to monitor flows, enforce tax rules and respond to external shocks. For a country that still relies on careful capital–account management, this is a serious concern.

4. Bank disintermediation

If a significant portion of deposits migrates from bank accounts into stablecoins, banks could lose a cheap and stable source of funding. That would either push up the cost of credit or force banks to shrink their balance sheets, with knock–on effects for growth and financial inclusion.

How other countries are dealing with stablecoins

Interestingly, India’s stance is among the toughest but not unique. Many advanced economies have chosen a different route: regulating stablecoins tightly instead of banning them outright.

– The European Union’s MiCA framework requires issuers of major “asset–referenced tokens” and e–money tokens to hold high–quality liquid reserves, maintain full redemption at par, and comply with strict disclosure and governance norms.

– Japan’s updated laws allow certain stablecoins, but only when issued by licensed banks, money transfer firms or trust companies under close supervision.

– Singapore has introduced a specific regime for single–currency stablecoins, including requirements around capital, reserve composition, redemption timelines and user disclosures.

In the US and UK, draft laws and policy proposals are moving in a similar direction – nudging stablecoin issuance towards banks or highly supervised entities, while treating large “systemic” stablecoins almost like narrow banks.

CBDC vs stablecoins: the RBI’s alternative vision

Rather than conceding the digital–money space to private tokens, central banks are building their own alternative – central bank digital currencies (CBDCs). The RBI’s retail and wholesale pilots for the digital rupee are part of this strategy.

The idea is simple. Give users the same benefits that stablecoins claim – instant settlement, programmability and cross–border efficiency. But in the safest possible form, a direct liability of the central bank. Combined with highly efficient payment rails like UPI, a CBDC can offer innovation without compromising monetary sovereignty.

Where does this leave crypto users?

If you are a crypto investor or a business experimenting with Web3, stablecoins will probably remain a key on–chain settlement tool for the foreseeable future. But it is important to recognise that regulators increasingly see them as potential threats. Threat on national financial systems, not as neutral payment utilities.

For Indian users, the direction of travel is clear. RBI is unlikely to permit stablecoins within the formal financial system any time soon. This is especially when a CBDC and interoperable fast–payment links can deliver similar functionality with far lower risk. Anyone experimenting with such tokens today is operating in a grey area that could face much stricter rules – or outright prohibition – down the line.

The bottom line: stablecoins are a fascinating bridge between traditional finance and crypto. But they are also a fault line where private innovation collides with public interest. Understanding that tension is essential before treating any token, however “stable”, as money.
