Longer voyages are re-pricing demurrage risk across bulk chartering

Demurrage used to be settled after the fact. In the current routing environment it is being negotiated before the fixture is signed, because the exposure it represents has grown faster than most standard charterparty clauses were written to handle.

The mechanics are straightforward. Sustained disruption to Red Sea and Suez transits has pushed a large share of Asia–Europe tonnage around the Cape of Good Hope, adding roughly ten to fourteen days to affected voyages and materially raising fuel burn. Longer legs compress arrival windows, make notice of readiness patterns less predictable, and concentrate arrivals at the alternative hubs — Singapore, Fujairah and Rotterdam among them — where congestion then feeds back into laytime.

Container-side data shows average global demurrage and detention charges rising around 8 per cent year on year in 2025, driven by congestion, shorter free-time allowances and back-to-back contracts that no longer align. Bulk operators face the same physical causes with different contractual plumbing: a Supramax waiting on a berth at a congested transshipment port accrues exposure whether or not the delay was foreseeable at fixture.

Energy and maritime trading house Alkagesta, in its own analysis of the demurrage landscape, makes a point worth repeating for bulk desks: claims are increasingly lost on documentation rather than on merits. Recent arbitration and court outcomes have turned on incomplete statements of fact, missing notice records, or claims submitted outside the contractual time bar. The commercial argument can be sound and still fail on evidence.

For chartering teams the implications are practical. Laytime assumptions built on pre-disruption voyage times understate exposure on any routing that touches the Cape. Time-bar clauses deserve a second read before signature, not after a claim. And the documentary chain — NOR, statement of facts, pumping and shifting logs, port agent correspondence — needs to be collected as the voyage runs, because reconstructing it three months later is where most value is lost.

The wider point is that demurrage has become a proxy for routing risk. As long as voyages stay long and ports stay congested, the clause that used to be a formality is doing real commercial work in the fixture.
