+# USD - ISK exchange rate
+
+Due to the financial crisis the USD/ISK exchange rate shows potential change 
+point behaviour in the years around 2008. Since it is difficult to find freely 
+available (and permissively licensed) historical exchange rate data, we 
+instead use the monthly average Euro/ECU exchange rates of both USD and ISK 
+and compute the USD/ISK rate from there.
+
+The Euro/ECU exchange rate can be obtained from [this direct 
+link](https://appsso.eurostat.ec.europa.eu/nui/show.do?query=BOOKMARK_DS-054904_QID_-3F48645A_UID_-3F171EB0&layout=TIME,C,X,0;CURRENCY,L,Y,0;UNIT,L,Z,0;STATINFO,L,Z,1;INDICATORS,C,Z,2;&zSelection=DS-054904UNIT,NAC;DS-054904INDICATORS,OBS_FLAG;DS-054904STATINFO,AVG;&rankName1=UNIT_1_2_-1_2&rankName2=INDICATORS_1_2_-1_2&rankName3=STATINFO_1_2_-1_2&rankName4=TIME_1_0_0_0&rankName5=CURRENCY_1_2_0_1&sortC=ASC_-1_FIRST&rStp=&cStp=&rDCh=&cDCh=&rDM=true&cDM=true&footnes=false&empty=false&wai=false&time_mode=NONE&time_most_recent=false&lang=EN&cfo=%23%23%23%2C%23%23%23.%23%23%23).
