Coreax (The Steam Age Map Game)

The  Corea Exchange is the world's only independent source of maritime market information for the trading  and settlement of physical and derivative  contracts.

The exchange provides daily freight market prices and maritime shipping cost indices which are used to settle  freight futures (known as  Forward Freight Agreements or FFAs).

Corea Dry Index
The  Corea Dry Index (CDI) is a number (in UKP) issued daily by the Seoul  based Corea Exchange . Not restricted to Asian  countries, the index provides an assessment of the price of moving the major raw materials by sea.

How it works
Every working day, a panel of international shipbrokers submits their view of current freight cost on various routes to the Corea Exchange. The routes are meant to be representative, i.e. large enough in volume to matter for the overall market.

The CDI contains route assessments based only on time-charter hire rates "UKP paid per day per Metric Ton". Fuel (="Bunkers") is the largest voyage dependent cost and moves with the crude oil price. In periods where bunker costs fluctuate significantly, there CDI will therefore move more than the shipowners' realised earnings.
