Baltic Exchange. Situated in London, England, this is the foremost shipping market-place in the world. Shipbrokers meet in the Exchange daily to charter ships and to exchange information. Trade is also carried out in commodities such as grain. The Baltic also lends its name to an "Index", the Baltic Freight Index (BFI). Since 1985 there has been a development of freight futures (BIFFEX), and these are also transacted on the "floor" of the Exchange.
Blockade. Belligerent powers have the right of blockade, i.e., the right to blockade enemy ports or coastal territory for ocean shipping by military measures.
