本研究對1985/1至2016/10期間，37種貨幣的超額報酬與國家風險進行實證分析，以The PRS Group發佈的ICRG綜合風險評級做為國家風險的衡量指標。各國貨幣分別進行時間序列分析的結果顯示，單一國家的國家風險與該國貨幣的匯率走勢及超額報酬並不存在顯著的關聯。
投資組合分析的結果，對高國家風險貨幣與低國家風險貨幣分別執行利差交易，結果顯示兩者的超額報酬並沒有顯著差異。而動能策略在高國家風險貨幣則可以獲得顯著較高的超額報酬。
Fama-Macbeth二步驟迴歸分析結果顯示，高國家風險的投資組合確實擁有較高的因子負載量，然而國家風險因子的市場價格，也就是承受一單位 β_CRISK獲得的國家風險溢酬太低不顯著，因此國家風險無法幫助解釋貨幣報酬。 / We empirically investigate the relation between currency excess returns and country risk, as measured by the ICRG comprehensive risk rating issued by The PRS Group, of 37 currencies during 1985/1 to 2016/10. The result of the single currency time series analysis shows that there is no significant correlation between the country risk and the exchange rate movement, also the currency excess return.
As a result of the portfolio analysis, there is no significant difference in excess returns when we execute carry trade respectively on high country risk currencies and low country risk currencies. While the momentum strategy in the high country risk currencies can generate significantly higher excess return.
The results of the Fama-Macbeth two-step regression show that the high-risk portfolios do have a higher factor loading, whereas the country risk factor's market price, that is, the country risk premium received by a unit of β_CRISK, is too low. Therefore, country risk cannot help explain currency excess return.
