Singapore has transformed its economy into an energy trading hub within a few decades. Such transformation was made possible by a strong government drive, private sector participation, and its natural geographical location as one comparative advantage. Institutional effort was another key driver for the successful transformation. Being an energy trading hub, Singapore is able to help create one price prevail across the markets. As a trading hub, Singapore not only physically connects various markets but also makes the law of one price prevail in the markets thereby promoting energy market integration.
