Singapore International Monetary Exchange

The Singapore International Monetary Exchange (SIMEX) was a financial derivatives exchange established in Singapore in 1984. It provided a marketplace for trading futures and options contracts linked to financial instruments, equity indices, currencies and commodities. SIMEX became known for its international derivatives markets and its role in connecting Asian and North American futures trading.

On 1 December 1999, SIMEX was merged with the Stock Exchange of Singapore (SES) and Securities Clearing and Computer Services to form the corporate structure of the Singapore Exchange (SGX). The merger brought securities and derivatives trading under an integrated exchange group.

History

Establishment

SIMEX was established in 1984 to develop an organized market for financial futures and derivatives in Singapore. Its creation formed part of Singapore's efforts to expand its financial services sector and strengthen its position as an international financial centre.

The exchange introduced futures contracts that enabled investors and financial institutions to manage exposure to changes in interest rates, equity indices and other financial variables.

International trading links

SIMEX became internationally recognized for its trading arrangements and cooperation with overseas derivatives exchanges. One of its most significant innovations was the Mutual Offset System (MOS), developed in cooperation with the Chicago Mercantile Exchange (CME).

The Mutual Offset System enabled eligible positions in specified futures contracts to be transferred between the two exchanges. This arrangement facilitated trading across Asian and North American time zones and contributed to the development of more continuous international derivatives markets.

A simplified representation is:

$A s i a n T r a d i n g \to C r o s s E x c h a n g e L i n k \to N o r t h A m e r i c a n T r a d i n g$

The system was an important development in the international integration of derivatives markets.

Merger with the Stock Exchange of Singapore

During the 1990s, changes in financial technology, international competition and the structure of financial markets increased the importance of integrated exchange infrastructure.

In 1999, Singapore undertook a restructuring of its exchange industry. SIMEX and the Stock Exchange of Singapore were demutualized and brought together under a common holding-company structure, alongside Securities Clearing and Computer Services.

The Singapore Exchange was formed on 1 December 1999 and listed publicly on 23 November 2000. The merger integrated securities and derivatives businesses within a single exchange group.

Market structure

SIMEX operated a derivatives market in which participants traded standardized contracts based on specified underlying assets or financial indicators.

Its products included contracts linked to:

equity market indices;
interest rates;
foreign exchange;
commodities; and
other financial instruments.

These contracts allowed participants to obtain market exposure, hedge existing positions and engage in trading strategies based on expected price movements.

Derivatives trading

SIMEX was primarily associated with futures and other derivatives rather than the direct trading of ordinary company shares.

A futures contract establishes an obligation to transact according to specified contractual terms at a future date or through cash settlement, depending on the product.

Derivatives can be used for hedging, speculation and arbitrage. Their value depends on the underlying instrument, contract specifications, market conditions and time to expiry.

A simplified relationship is:

$U n d e r l y i n g A s s e t \to F u t u r e s C o n t r a c t \to R i s k M a n a g e m e n t$

Mutual Offset System

The Mutual Offset System was one of SIMEX's most significant contributions to international derivatives trading. Developed in cooperation with the Chicago Mercantile Exchange, it linked trading in specified contracts across the two exchanges.

The system enabled eligible positions to be offset between the participating exchanges under agreed rules. This reduced some operational barriers associated with trading the same or related contracts across different time zones.

The arrangement demonstrated how technological and institutional cooperation could extend market access beyond a single exchange's local trading hours.

Economic significance

SIMEX contributed to Singapore's development as an international financial centre by establishing a recognized venue for derivatives trading and attracting participation from international financial institutions.

Its activities supported the development of financial risk-management services, trading infrastructure and cross-border market connectivity.

The exchange also helped establish a foundation for Singapore's later integrated securities and derivatives market infrastructure under SGX.

Legacy

Although SIMEX ceased to operate as a separate exchange following the 1999 merger, its derivatives business became part of the Singapore Exchange's broader market infrastructure.

The merger preserved the integration of securities and derivatives services within Singapore's exchange system. The international trading links pioneered by SIMEX also formed part of the wider development of cross-border derivatives markets.

SIMEX is therefore associated with the evolution of Singapore's financial markets from separate securities and derivatives exchanges to an integrated exchange group serving domestic and international participants.
