In the final months before Zimbabwe's central bank reforms of 30 April 2008, virtually all popular currency conversion resources relied upon the official rate of 30,000 ZWD to US$1 for published figures, in spite of the vast differences between that and free market rates. By 23 May 2008, Bloomberg[153] and Oanda[154] began publishing floating rates based on Zimbabwe's formally regulated domestic bank market, while Yahoo Finance started using the updated official rate in July, albeit with a decimal point shift of 6 places. Those reported rates generally reflected the Official Rate as shown in the above table.
