All website spot port prices (e.g. Singapore VLSFO) are updated daily, between Monday and Friday (see 'Public holidays' below for exceptions).
Bunker Index generally collects and publishes spot port prices whilst trading is taking place in each market in order to provide users with up-to-date prices.
The precise timing of updates for a port on any given day will depend on a number of factors, including:
'Last' APIs update automatically to show the last spot price published for each port product (e.g. Singapore VLSFO). For example, if the time were 00:05 GMT and the price for Singapore VLSFO had not yet been added for the current day, then the last spot price published for the previous day would be shown.
'Today' APIs update automatically to show the last spot price published for each port product during the current day (GMT) only. For example, if the time were 00:05 GMT and the price for Singapore VLSFO had not yet been added for the current day, then no price for Singapore VLSFO would be shown.
'End of day (EOD)' APIs show the last spot price published for each port product on the previous day. They automatically become available at 00:00:01 GMT of the current day.
Forward port prices (web and API) for a given trade date and delivery date/month are published once a day, between 00:00 and 02:00 GMT the following day.
All monthly spot port averages (web and API) are published between 00:00 and 12:00 GMT on the first day of each month for the previous month.
All quarterly spot port averages (web and API) are published between 00:00 and 12:00 GMT on the first day of each quarter (Jan 1, Apr 1, Jul 1, Oct 1) for the previous quarter.
All yearly spot port averages (web) are published between 00:00 and 12:00 GMT on the first day of each year (Jan 1) for the previous year.
BIX Indices (web and API) for a given date are published once a day, between 00:00 and 06:00 GMT the following day.
