Indicators of security of natural gas supply in Asia

Natural gas has become an increasingly valuable resource and a global commodity. The demand for it has significantly increased. Japan, Korea and Taiwan heavily rely on liquefied natural gas (LNG) imports for their gas supplies from Malaysia, Brunei, Indonesia, Australia and the Middle East. On the other hand, countries like Thailand and Singapore import gas via trans-border pipelines. Gas supply interruptions, volatile gas prices, transportation and distribution bottlenecks, and a growing reliance on imports over longer distances have renewed interest on gas security in Asia. This paper examines the relative vulnerability to natural gas supply disruptions of seven gas-importing countries in Asia for year 2008. Based on four indicators of security of gas supply, a composite gas supply security index is estimated as an overall indication of gas vulnerability for our sample countries. The results demonstrate that there are differences in the values of the overall indicator of gas vulnerability among countries and the assessment is useful in developing an effective strategy of natural gas supply security in countries in the Asian region.
