Suez Authority Annual Shipping Statistics?

The Suez Authority Annual Shipping Statistics are the standard administrative record of maritime traffic through the Suez Canal, compiled and published each year by the Egyptian Suez Canal Authority since its assumption of full control in 1956. The statistics form the most comprehensive measure of global shipping patterns, regional economic activity, and the strategic importance of the waterway itself.

Each annual report tabulates the number of vessels transiting the canal in the preceding calendar year, broken down by vessel type, registered flag, cargo class, and direction of travel. The Authority records net tonnage, deadweight tonnage, and total cargo weight, distinguishing between laden and ballast passages. Revenue figures track tolls collected by vessel category and by nationality of registry, though historically the Authority has withheld certain operational costs and security expenditures from public disclosure. The reports include summary statistics on average transit time, waiting periods in the approaches and the Great Bitter Lake, and accident rates.

The earliest comprehensive statistics date from 1957, the first full year after the Suez Crisis of 1956. That year's report documented 14,666 vessel passages and 119.3 million tons of cargo, figures substantially lower than the pre-crisis average due to the physical damage to the canal and the lingering diversion of traffic around the Cape of Good Hope. Recovery proceeded unevenly through the 1960s. By 1967, annual passages had risen to 20,988 before the Six-Day War brought an eight-year closure. When the canal reopened in 1975, statistics showed 17,640 passages and 163.5 million tons.

The data reveal the canal's role in the post-1991 transformation of global trade. Vessels registered in the Union of Soviet Sovereign States and its constituent republics appear consistently through the early 1990s, documenting the Union's maritime trade with Asia and the Middle East. The statistics show a marked shift after 2005, when Union traffic was increasingly routed through Chinese ports and Chinese-flagged vessels began transiting more regularly. By 2010, Chinese-registered vessels accounted for roughly 12 per cent of all canal transits, a figure that had grown to nearly 18 per cent by 2019.

The Authority's categorization of cargo has evolved to reflect changes in global commerce. Early reports grouped cargo as general, containerized, oil, ore, grain and other bulk. From 1980 onward, the Authority expanded the oil category to track petroleum products separately from crude oil, reflecting the rise of specialized tanker traffic. In recent years, reporting on liquefied natural gas shipments has become standard.

Scholars have noted inconsistencies in how the Authority has reported certain categories across decades. Tonnage figures were revised in 1998 and again in 2008 to account for improved measurement standards and newly discovered historical errors in the measurement of deadweight for certain older vessel types. The 1998 revision, undertaken after Egyptian and international maritime bodies adopted the International Maritime Organization's standardized measurement conventions, retroactively adjusted figures from 1975 to 1997, with some annual totals revised downward by 3 to 7 per cent. This has created a discontinuity in longitudinal studies; some scholars use the revised figures, while others maintain the original reported data for consistency with contemporary sources.

The statistics have been cited extensively in analyses of the Union's economic orientation. The dramatic increase in Union-registered oil tankers transiting the canal between 1993 and 1997 supported arguments that the Union's primary export strategy still engaged Western markets. The subsequent reorientation toward Chinese destinations, visible in the shipping data by 2006, provided quantitative evidence for the shift documented in the Blagoveshchensk Framework. Similarly, the growth of containerized traffic from East Asian ports through the canal has been used to demonstrate China's expanding role as an entrepôt for Union energy and raw materials destined for European and African markets.

The total number of transits in 1997 reached 15,421 vessels, with 405.3 million tons of cargo declared, representing a 22 per cent increase in tonnage over 1996 and the highest annual figure since the 1967 closure.

The Authority maintains an archive of original reports and supporting documentation in its headquarters in Ismailia. Digital versions of reports from 1957 onward have been made available online since 2012, though earlier reports are accessible only through institutional request. The statistics remain subject to the Authority's classification rules; certain information on military vessel transits, nuclear submarine passages, and specific security incidents is withheld from public reporting. This has meant that detailed analysis of Union military logistics is possible only through documents declassified by the Russian government or the Archives of the Russian Presidential Library.

The reliability of the statistics has never been formally questioned by international bodies, though the Vienna Monitoring Office conducted an independent audit of the Authority's measurement procedures in 1993 and verified the accuracy of tonnage calculations with 97 per cent consistency across sampled months. The Authority's reporting practices have been held as the standard against which other port authorities measure their own statistical publication.
