The short version
- SIMEX opened in 1984 and merged with the Stock Exchange of Singapore and SCCS to form SGX in 1999.
- SGX launched Bitcoin and Ether perpetual futures in 2025, but Singapore-based access is restricted to accredited, expert and institutional investors.
- Retail spot crypto services sit under a separate MAS licensing and customer-protection framework.
- A Singapore licence does not remove price, custody, fraud, leverage or tax-record risks.
How SIMEX Became Part of SGX
The Singapore International Monetary Exchange, better known as SIMEX, was established in 1984. SGX’s own history calls it Asia’s first financial futures exchange. It gave banks, brokers and companies a Singapore venue for contracts tied to interest rates, currencies and market indexes. A futures contract tracks an underlying market; it is not the same as buying the underlying asset itself.
SIMEX did not simply change its name to SGX. On 1 December 1999, it merged with the Stock Exchange of Singapore and Securities Clearing and Computer Services. The combined company became Singapore Exchange, or SGX. That history explains why people still use SIMEX when discussing Singapore derivatives, even though current contracts, rules and membership now sit under SGX.
The distinction matters for crypto. SIMEX was never a retail cryptocurrency platform, and the old name does not describe a current Bitcoin exchange. SGX is now an approved securities and derivatives market with its own products and access rules. Singapore’s broader Bitcoin regulation framework also covers payment-token providers outside the SGX market.

What SGX Crypto Perpetual Futures Offer
SGX Derivatives launched Bitcoin and Ether perpetual futures on 24 November 2025. These contracts have no scheduled expiry and use iEdge CoinDesk cryptocurrency indexes as benchmarks. They bring crypto price exposure into an exchange-cleared system with formal margining. They do not place bitcoin or ether in the buyer’s wallet, because the product is a derivative position rather than an on-chain purchase.
Access is narrow. SGX Directive No. 3 requires members to restrict Singapore-based customers to accredited, expert or institutional investors. An ordinary retail customer cannot assume that a brokerage account or permission to buy SGX shares also permits these contracts. A broker must apply the eligibility controls, and it may impose its own onboarding, margin and product-knowledge requirements as well.
Perpetual futures can magnify gains and losses because traders post margin instead of paying the full notional exposure. A sharp move can trigger extra margin demands or force a position to close. Central clearing reduces one kind of bilateral counterparty risk, but it does not cancel market risk, basis risk or liquidation risk. The site’s volatility explorer shows why leverage deserves special care.
| Route | What the customer holds | Singapore access | Main risks |
|---|---|---|---|
| Licensed spot service | Token balance or custody claim | Retail may be accepted | Price, platform, custody |
| SGX crypto perpetual | Margined futures position | Accredited, expert or institutional | Leverage, margin, liquidation |
| Self-custody after withdrawal | Keys controlling on-chain tokens | Depends on withdrawal support | Key loss, scams, transfer errors |

How MAS Rules Apply to Spot Crypto Services
Spot trading follows a different route. Under the Payment Services Act, MAS regulates services such as buying or selling digital payment tokens, custody, transfers and exchange facilitation. The licence belongs to the service provider and covers stated activities. It is not approval of every token on the platform, a guarantee that prices are fair, or insurance against a provider’s failure.
Rules introduced from 2024 expanded the regulated activities and strengthened customer-asset safeguards. MAS requires measures such as segregating customer assets, placing them in trust, keeping proper records and maintaining systems that protect those assets. Providers also perform identity checks and transaction monitoring under anti-money-laundering rules. These controls reduce some operational risks, but MoneySense warns that customers can still lose all their money.
The practical check is the MAS Financial Institutions Directory. Search the exact legal company name, then confirm that its listed activity includes digital payment token service. Match the official website rather than trusting an advertisement or app-store name. An overseas registration, a pending application or a Singapore office address is not the same as an active MAS licence for the service being offered.

Spot Trading, Custody and Costs Need Separate Checks
A spot order should identify both sides of the pair. BTC/SGD exchanges bitcoin for Singapore dollars, BTC/USD uses U.S. dollars, and BTC/USDT uses a stablecoin issued by Tether. USDT aims to track the dollar but is not a bank dollar. Compare the pair, venue and timestamp when reading a quote; the market dashboard keeps USD and USDT observations separately labelled.
The displayed trading fee is only one cost. A platform can also have a bid-ask spread, deposit fee, currency-conversion charge and withdrawal fee. Custody changes the risk again. Leaving assets with a provider creates platform and insolvency exposure; withdrawing them creates personal key-management duties. A Bitcoin wallet guide explains how a wallet manages keys rather than storing coin files.
Before using any route, document what is being bought, who holds it and how an exit works. Sensible checks focus on verifiable details rather than return claims:
- Confirm the legal entity and regulated activity in the MAS directory.
- Read the pair, order type, spread, margin terms and full fee schedule.
- Check withdrawal limits, supported networks and custody arrangements.
- Use unique login credentials, strong two-factor authentication and a tested recovery plan.

Using the SIMEX-to-SGX History to Understand Singapore Crypto Trading
Tax treatment depends on the facts. IRAS says gains from digital tokens held as personal investments are generally not taxable because Singapore has no capital gains tax. However, profits can be taxable when the activity amounts to a trade or business. Purpose, transaction frequency and holding period can matter, so “crypto is tax-free in Singapore” is too broad to be reliable.
GST is a separate issue. Since 1 January 2020, exchanging qualifying digital payment tokens for fiat money or other digital payment tokens is generally an exempt supply. Using such a token to pay does not itself create another supply of the token, but the purchased goods or services may still carry GST. Records of dates, Singapore-dollar values, fees and transfers support any later tax analysis.
SIMEX helped establish Singapore as a derivatives centre; SGX now applies that market structure to restricted-access Bitcoin and Ether perpetual futures. MAS-licensed spot services serve a different function, and self-custody adds a third risk model. Understanding which track applies is more useful than treating “Singapore-regulated crypto” as one label. Regulation sets rules for providers and venues; it cannot make a volatile asset safe.
