Currency internationalization and valuation effects: based on the threshold model

ABSTRACT

Based on the three functions of currency internationalization, including exchange medium, pricing currency and foreign reserve, this paper explores how the degree of currency internationalization affects the impact of the exchange rate and the asset price on valuation effects. Using samples of 161 countries or regions from 2001 to 2016 and the threshold regression method, we find that, firstly, there is a threshold effect of the exchange rate on valuation effects due to currency internationalization. The higher the comprehensive level of currency internationalization is, the greater the positive impact of the exchange rate on valuation effects will be. Secondly, the threshold effect of the asset price on valuation effects due to currency internationalization is not significant because of the high stickiness of asset price. Besides, compared with developed countries, currency internationalization is more important to increase valuation effects through exchange rate channel and asset price channel in developing countries or regions. Finally, there are some differences in the three types of currency internationalization functions. The promotion of exchange medium function will lead to a greater positive impact of the exchange rate on valuation effects, as well as pricing currency function. However, the foreign reserve function has no such effect.
