It takes more than just demand from shippers to make these derivatives viable. You need indexes against which bourses can measure a derivative's value; the World Container Index from Drewry and Cleartrade now exists. You need counterparties ready to underwrite derivatives; some shippers are starting to take the other side of contracts.
The market for freight rate derivatives won't be fully mature until major investment firms take on large roles in underwriting and the derivatives are regulated and traded on exchanges. Like all derivatives, they are subject to abuse by traders who misuse them or misrepresent their risks to investors.
Derivatives offer shippers a tool that can complement traditional long-term delivery contracts. This is a welcome development.
