The Panama Ship Registry has fallen to third place by gross tonnage in the latest 2026 Clarksons fleet ranking, after the Marshall Islands moved into second while Liberia retained a commanding lead.
The shift is more than a change in a league table. It shows how competition between the world’s largest open registries is moving toward fleet quality, sanctions compliance, technical support, Port State Control performance and the ability to attract newer tonnage.
Who has the largest ship registry in 2026? In the Clarksons World Fleet Commercial and Merchant dataset cited by Seatrade Maritime, Liberia ranks first with 314.6 million GT, the Marshall Islands second with 209.4 million GT and Panama third with 202.1 million GT.
Panama Ship Registry Drops to Third by Gross Tonnage
The latest ranking marks another important change in a registry market that was dominated by Panama for decades.
According to Seatrade Maritime’s reporting on the 2026 Clarksons World Fleet Register, Panama now has 202.1 million gross tons across 7,677 vessels in the relevant commercial and merchant fleet dataset.
The Marshall Islands moved into second position with 209.4 million GT and 4,732 vessels, while Liberia remains first with 314.6 million GT and 6,138 vessels.
| Rank | Registry | Gross tonnage | Vessels |
|---|---|---|---|
| 1 | Liberia | 314.6m GT | 6,138 |
| 2 | Marshall Islands | 209.4m GT | 4,732 |
| 3 | Panama | 202.1m GT | 7,677 |
One detail stands out immediately: Panama still has more vessels than either Liberia or the Marshall Islands in this dataset, but it no longer has the same concentration of large-vessel tonnage.
That distinction is central to understanding registry rankings. A flag can have more individual vessels and still rank lower when the comparison is based on gross tonnage.
Panama-Flagged Tonnage Fell 12.3% From End-2025 to August
The change was not caused only by the Marshall Islands growing.
Seatrade reported Clarksons figures showing Panama-flagged tonnage falling from 230.5 million GT at the end of 2025 to 202.1 million GT by August 2026.
That is a reduction of 12.3%.
Over the same comparison period, the Marshall Islands fleet grew by 7.0% to 209.4 million GT, allowing it to move ahead of Panama.
Why Is Panama Losing Registered Tonnage?
There is no single explanation for the decline.
Panama’s registry says it has been pursuing a more selective policy focused on quality over quantity, including stronger fleet-performance monitoring and the removal of vessels with poor performance or sanctions exposure.
Seatrade also reported that Panama has removed substantial tonnage in connection with US sanctions compliance.
At the same time, the registry said that some periods in 2026 saw increased cancellation requests coinciding with higher detention activity at certain ports, prompting additional inspections of vessels classified by the flag as high risk.
That matters because a registry’s commercial position is shaped by more than registration fees.
- Port State Control performance affects detention exposure.
- Sanctions compliance can determine whether a vessel remains acceptable to banks, insurers and counterparties.
- Technical support affects how quickly owners can resolve statutory issues.
- Registry service quality matters when certificates, exemptions and approvals are time-sensitive.
- Newbuilding registrations determine whether a flag is replacing older tonnage with younger, higher-value ships.
For the operational side of detention exposure, Tide Signal’s Port State Control inspection guide explains how deficiencies, statutory compliance and crew readiness can affect a vessel’s ability to continue trading.
Panama Says It Is Choosing Quality Over Quantity
Ramon Franco, head of the Panama Ship Registry, said the registry’s priority is to maintain higher-quality vessels and become more selective where necessary.
The position is important because falling tonnage can be interpreted in two very different ways.
From a purely competitive perspective, a reduction in registered GT means lost market share.
From a regulatory perspective, however, removing sanctioned or persistently underperforming vessels can improve the quality profile of the remaining fleet.
The real test will be whether Panama can replace cancelled tonnage with newer vessels and newbuildings rather than simply shrinking.
Marshall Islands Moves Into Second Place
The other side of the story is the continued growth of the Republic of the Marshall Islands Registry.
An official Republic of the Marshall Islands Registry snapshot published on 28 August 2026 says it ranked second in Clarksons’ August World Fleet Monitor and reported more than 221 million GT across more than 6,650 vessels, with 221,369,700 GT and 6,652 vessels as of 31 July.
Those figures are higher than the 209.4 million GT and 4,732 vessels in the specific Clarksons commercial-and-merchant dataset cited in the latest Panama ranking report.
Do not mix registry statistics without checking the dataset. Different sources may use different reporting dates, vessel categories and fleet universes. A registry’s own total fleet can therefore differ from a commercial-and-merchant subset used for a ranking.
The direction of travel is nevertheless clear: the Marshall Islands has continued to expand its position among the largest international flags.
Liberia Remains the Clear Global Leader
Liberia remains well ahead of both competitors in gross tonnage.
The Liberian Registry says it now represents more than 300 million GT and around 18% of the world’s ocean-going fleet, citing Clarksons WFR data from September 2026.
Its current lead is substantial enough that the immediate competition is less about first versus second and more about whether Panama can recover the ground lost to the Marshall Islands.
Why Shipowners Change Flag
A vessel’s flag is a regulatory and commercial decision, not simply a national symbol painted on the stern.
The flag state is responsible for implementing international conventions on vessels registered under its authority, including requirements arising from SOLAS, MARPOL, STCW, the ISM Code and other international instruments.
For owners, registry selection can therefore involve:
- quality and speed of technical support;
- registration and annual costs;
- global availability of survey and certification services;
- Port State Control performance;
- sanctions and compliance risk;
- mortgage and corporate-law frameworks;
- recognition by charterers, banks and insurers;
- digital certificate capability;
- crew documentation;
- and support during casualties or urgent regulatory cases.
For the practical inspection side of flag performance, see Tide Signal’s Port State Control Inspection: What Ships Must Prepare Before Arrival and the current Port State Control CIC 2026 guide.
The international safety framework behind flag-state obligations is explained in Tide Signal’s SOLAS Convention guide.

Gross Tonnage vs Deadweight: Why Rankings Can Look Different
One of the easiest mistakes in reporting ship-registry rankings is to compare statistics that use different measurements.
Gross tonnage (GT) is a measure related to the overall internal volume of a ship.
Deadweight tonnage (dwt) measures how much weight a ship can carry, including cargo, fuel, stores, water and other variable loads.
UN Trade and Development’s 2026 fleet data, using beginning-of-year carrying capacity in deadweight tons, lists Liberia at about 447 million dwt, Panama at 350 million dwt and the Marshall Islands at 318 million dwt.
That dataset therefore still shows Panama ahead of the Marshall Islands because it is a different measurement taken at a different point in time.
Panama’s Own Current Figures Also Differ
The Panama Maritime Authority’s current website displays approximately 7,832 flagged vessels and 200.6 million gross registered tons.
Again, those figures do not exactly match the 7,677 vessels and 202.1 million GT in the specific Clarksons dataset cited by Seatrade.
That is not necessarily a contradiction. Registry databases are live, vessels enter and leave continuously, and commercial datasets apply their own vessel-category definitions and cut-off dates.
For market analysis, the important discipline is to identify the source, measurement and date before comparing figures.
Why the Ranking Matters Commercially
The registry battle matters because the largest flags sit at the centre of the global compliance chain.
They issue or oversee statutory documentation, delegate survey work to recognised organisations, monitor fleet performance and interact with owners, class societies, Port State Control authorities and international regulators.
Scale can create significant commercial advantages: a global service network, 24-hour technical support, experienced casualty teams and familiarity among shipowners and financiers.
But scale can also increase exposure. A very large registry must monitor thousands of ships operating across every major trade, including older vessels, high-risk trades and ships affected by sanctions.
That makes fleet quality increasingly important alongside fleet size.
Can Panama Regain Second Place?
The gap is not enormous in percentage terms.
On the Clarksons figures cited in the latest ranking, the Marshall Islands is roughly 7.3 million GT ahead of Panama.
A recovery is therefore possible if Panama stabilises cancellations and attracts significant newbuilding or younger-vessel registrations.
But competition will remain intense.
Liberia and the Marshall Islands are both actively targeting large modern ships, and owners increasingly evaluate registries on regulatory performance, service responsiveness, detention prevention and sanctions-risk management rather than scale alone.
The next meaningful signal will therefore not be whether Panama adds a few hundred ships.
It will be whether the registry can rebuild high-quality gross tonnage while improving the risk profile of the fleet.
Panama Ship Registry Ranking: Frequently Asked Questions
What is the world’s largest ship registry in 2026?
In the Clarksons commercial-and-merchant fleet ranking cited in this report, Liberia is first by gross tonnage with 314.6 million GT, followed by the Marshall Islands with 209.4 million GT and Panama with 202.1 million GT.
Is Panama still the world’s largest ship registry?
Not in the latest Clarksons ranking by gross tonnage used here. Panama ranks third behind Liberia and the Marshall Islands. Rankings can differ when another date, fleet universe or metric such as deadweight tonnage is used.
Why did the Panama Ship Registry fall to third place?
The latest reporting points to a combination of falling Panama-flagged gross tonnage, selective removals of poorly performing or sanctioned vessels, cancellation requests and competitive growth by other registries, especially the Marshall Islands.
How many vessels are registered under Panama?
The Panama Maritime Authority currently displays about 7,832 flagged vessels. The specific Clarksons commercial-and-merchant dataset cited by Seatrade lists 7,677 Panama-flagged vessels, illustrating why source definitions and cut-off dates matter.
Why do UNCTAD and Clarksons rankings differ?
They can use different reporting dates, fleet definitions and measurements. The Clarksons ranking discussed here is based on gross tonnage, while UNCTAD’s cited 2026 carrying-capacity comparison uses deadweight tonnage.
