Based on careful inspection and statistical analysis of Taiwanese data, a co-integration test among the oil price, gold price and exchange rate shows no co-integration relationship among these three variables, which means that the long term stabilization of these three variables does not exhibit any shadowing relationships among the oil price, exchange rate and gold price. A closer look at the causal relationship among the three variables reveals that the oil price and the exchange rate have a two-way feedback relationship and the gold price leads the exchange rate and is not affected by the other variables. Furthermore, impulse response analysis shows that when interference strikes the three variables, its effects are strongest on the first day and will disappear within three to four days. Furthermore, based on the outcome of the variance decomposition analysis, following unexpected changes the gold price can be up to 99% self-explanatory, while the exchange rate and oil prices are 93% and 88% self-explanatory, respectively. These results show that, in Taiwan, no shadowing relationships were found among oil price, exchange rate and gold price in the long term; and the impact durations among these variables were relatively short despite the existence of some causality patterns in the short term. The oil price, gold price and exchange rate thus remain independent from one another. Fluctuations in energy prices and financial variables frequently affect the whole economy. If the two have an impact on each other then when evaluating the effect of the adjustment of one variable, the influence of the other must also be considered. This study explores whether energy price changes because of energy policy adjustments arouse financial variable fluctuations, and whether the financial policy adjustments influence energy prices. As concluded from the example of Taiwan, the sample period contains no evidence of a long term correlation between the oil, gold and exchange rate markets. The correlations were very short term. The oil price, gold price and exchange rate thus remain largely independent of one another. These results imply that energy policies should also be independent. Primarily focusing their concern on the goals of these policies, and the focus should be on policy goals rather than concern about economic disturbance due to the policy impacts on financial variables (exchange rate, gold price etc.). Restarted, energy policies should be independent and policymakers should consider the detachment of energy and financial policies. The framework of this study can be used to discuss other variables and empirical studies involving other countries, to clarify matters for decision makers when assessing whether the financial variables should be taken into account when assessing the effect of energy policies.
