Currency Interchangeability Agreement Between Singapore and Brunei: What It Means for Businesses and Travellers

In 1967, Singapore and Brunei both gained their independence from the British Empire. Since then, these two countries have maintained close diplomatic and economic relations. One significant aspect of their economic partnership is the Currency Interchangeability Agreement (CIA) that was established in 1967.

The CIA enables the currencies of Singapore and Brunei to be used interchangeably at par value, meaning that they can be used interchangeably for payment in either country. This agreement has benefited businesses and travellers who frequently travel between these two countries.

Benefits for Businesses

The CIA has made transactions between businesses in Singapore and Brunei more convenient as they do not have to deal with currency conversions or exchange rates. This has saved time and money for businesses, especially those who work in imports and exports. By eliminating the need for currency conversion, businesses can focus on other important aspects of their transactions.

Moreover, the CIA has also provided businesses with greater flexibility in managing their foreign currency reserves. Instead of holding separate reserves of Singapore dollars and Brunei dollars, they can hold a single reserve of either currency.

Benefits for Travellers

For travellers, the CIA has made traveling between Singapore and Brunei much easier. Tourists can use their Singapore dollars to purchase goods and services in Brunei without the need for currency exchange. This has made shopping and dining in Brunei more convenient and hassle-free.

Additionally, the CIA has enabled greater price transparency, making it easier for tourists to compare prices between the two countries. This has also helped to prevent price discrimination against tourists, improving the overall travel experience.


The Currency Interchangeability Agreement between Singapore and Brunei has been a significant development in the economic relationship between these two countries. It has facilitated trade and investment, improved price transparency, and made travel between the two countries more convenient. Businesses and travellers alike can benefit from this agreement and its effects on the economies of Singapore and Brunei.
