The main purpose of the study is to analyze the effective factors on fiscal instability of oil-exporting countries at different levels of dependency on oil revenues based on the threshold panel approach. Due to the ineffectiveness of the overall balance-of-budget indicator in oil countries as the basis for analyzing the government's fiscal policy, in this study, "The ratio of Non- Oil budget deficit to Non- Oil GDP" is used to measure the financial instability indicator in 2006- 2015 period. The findings of the research, while confirming the existence of threshold effect (ratio of the oil revenues to total government revenues) in the model, show that with increasing government revenue due to cash seigniorage as well as rising inflation, financial instability increase. In addition, if the dependence on oil revenues is higher than the threshold level calculated (29%), the effect of dependency on oil revenue on the financial instability index is more than 3 times, when dependency on oil revenue will be lower than threshold level. The findings of this study confirm the necessity of planning and orientation in oil exporting countries in order to reduce the structural dependency of the state budget on oil revenues.
