GLOBAL SCHEDULE RELIABILITY CLIMBED IN MAY DESPITE TRADE DISRUPTIONS
July 7, 2025
Global shipping schedule reliability rose sharply in May, according to a new Sea-Intelligence report — the highest level in 18 months.
In May 2025, schedule reliability recorded a 7.4 percentage point improvement month-on-month (M/M) and reached 65.8%.
In May 2025, schedule reliability recorded a 7.4 percentage point improvement month-on-month (M/M) and reached 65.8%.
"This is the highest figure recorded since November 2023 and continues the trend of consistent M/M improvements since February this year," Sea-Intelligence said.
It added on a year-on-year (Y/Y) level, schedule reliability was up 10.0 percentage points.
For May 2025, Sea-Intelligence said Maersk was the most reliable top-13 carrier with schedule reliability of 75.9%, followed by Hapag-Lloyd with 72.5%.
The next 6 carriers were in the 60%-70% range, and the remaining carriers were in the 55%-60% range. Meanwhile, Ocean Network Express (ONE) had the lowest May 2025 schedule reliability of 55.1%.
Sea-Intelligence said traditionally, alliance scores are based on just the arrivals in destination regions, but as that metric was not available for the new alliances in February, the maritime consultancy company introduced a new measure, based on all arrivals, including the origin region calls on the East/West trades.
"We continue to present both measures, 'All arrivals' which is comparable to the February measure, and 'Trade arrivals', which is comparable to the 'old' alliances," Sea-Intelligence said, adding that when the new alliances are fully rolled out, these two measures will converge.
In April/May 2025, Gemini Cooperation recorded 90.9% schedule reliability across ALL arrivals, and 88.4% across TRADE arrivals, followed by MSC at 70.5% for ALL arrivals and 77.9% for TRADE arrivals, while Premier Alliance recorded 55.2% for ALL arrivals and 52.7% across TRADE Arrivals.
For the "old" alliances, "ALL arrivals" are equal to "TRADE arrivals", and Ocean Alliance scored 57.4%.
The new alliances will roll out fully in July 2025; their performance can only be evaluated after that point.
