Multipurpose vessel (MPV) operators are feeling better about the market, and the reason is not a surge in cargo volume but capacity getting tied up. The Journal of Commerce Breakbulk Ship Capacity Indicator has dropped to its lowest reading since the index was launched in February 2025, signaling fewer available slots for breakbulk and heavy-lift cargoes.
Port congestion and vessel delays are the direct drivers. Every extra day a ship waits outside a port pushes the next cargo's schedule back, locking capacity in anchorages and at berths. For MPV owners, supply has contracted passively, giving them more pricing room than at the start of the year.
This segment is separate from the container fleets used for standard ocean parcel and ocean truck delivery, but the effects can spill over. Heavy-lift and breakbulk ships carry machinery, project cargo and oversized equipment. When those shippers cannot get space, they turn to container ships or chartering, indirectly absorbing some container capacity.
For shippers moving cargo from China to the US, bookings for out-of-gauge, overweight or special-handling cargo need a wider lead time than standard container freight. Regular ocean parcel shipments are not directly hit for now, but if US port congestion persists, schedule delays will eventually reach container vessels.
