從2009年7月1日開始，BDI使用新算法，如下：
The proposed BDI has an equal weighting of the timecharter averages of the BCI, BPI, BSI and BHSI and is a continuation of the present timeseries. For the creation of BDI we now use the following formula: ((CapesizeTCavg + PanamaxTCavg + SupramaxTCavg + HandysizeTCavg)/ 4) * 0.113473601 Where TCavg = Time charter average.
