A spot rate is the price for a booking made at current market conditions, valid briefly and moving with demand. A contract rate is agreed for a period, commonly annual on east-west trades, between shipper and carrier, trading price stability and allocation commitments for volume.
The two markets discipline each other: when spot sits far below contract, shippers drift to spot and carriers under-deliver contract allocations reluctantly; when spot spikes, contract cargo gets squeezed for space and premium products appear. Index-linked contracts split the difference by floating with published indices.
Contracts buy more than price: space protection in tight markets, free-time terms, and service commitments. Spot buys flexibility and upside in soft markets. Most sizeable shippers run a deliberate mix, contracting a base volume for certainty and playing the spot market for the remainder, with the ratio tuned to how badly a missed sailing hurts their business.
Whichever way you buy, performance is verifiable only operationally: did booked cargo ship, roll, or wait? Tracking your shipments per carrier in TrackingMCP builds the delivery record, rollovers, transit times, reliability, that anchors the next negotiation on data rather than anecdote.

Transpacific contracts traditionally run May through April, negotiated in the first quarter; Asia-Europe practice varies more. Spot quotes are valid days to weeks at most.
No. In soft markets spot undercuts contract, sometimes dramatically; in tight markets contract holders are protected. The premium buys predictability, not a guaranteed discount.
