What it means
Ships cross many national waters, so it would be unworkable if each country had different rules for the same vessel. The IMO provides a single global framework, which member states then put into law and enforce on ships flying their flags and visiting their ports.
The IMO was established under the United Nations to provide exactly that common framework. Its best-known agreements include conventions on the safety of life at sea and on the prevention of pollution from ships.
These set minimum standards for construction, equipment, crew qualifications and the handling of oil, chemicals and waste. Ships must carry certificates to prove they comply, and port inspectors can detain vessels that do not.
Rules can have a direct effect on shipping economics. Limits on the sulphur content of marine fuel, for example, forced ship owners to switch to cleaner fuel or fit exhaust cleaning systems, and both choices raised costs that were passed on in freight rates.
Fuel is one of the largest voyage costs, so any change to it moves the economics of a route. For finance teams the connection shows up in several places.
Freight and insurance costs, ship valuations, the cost of financing vessels and the decision to charter or buy a ship can all change when new regulations arrive. Emissions rules are an increasing focus.
Targets to reduce greenhouse gas emissions from shipping push owners to invest in more efficient engines, alternative fuels and slower speeds, and lenders now assess how well a ship or fleet is positioned for those changes. Vessels that look inefficient may be harder to finance or insure on good terms.
The nuance is that the IMO does not police ships itself. Enforcement rests with the flag state that registers the vessel and the port states where it docks, so the real-world effect depends on how strictly each country applies the rules.
In practice
Real-world examples.
Example
A shipping company with a fleet of bulk carriers must meet new fuel-quality limits. Its finance director compares the extra cost of cleaner fuel with the cost of fitting exhaust cleaning equipment on each ship. She chooses a mix, based on how long each vessel will stay in service and how much cash the company can commit to the upgrades.
Example
A bank financing the purchase of a tanker checks whether the ship complies with current IMO safety and pollution conventions. The loan agreement requires the owner to keep the vessel certified. If the certificates lapse, the bank can call the loan, so the borrower's treasury team tracks renewal dates closely.
Example
An importer of electronics notices that freight rates on a key route rise after new environmental rules take effect. The importer's procurement team adds a fuel and regulation surcharge clause to its contracts with customers. This protects its margin when carriers pass on higher costs, and the clause is written so that it cannot be used to raise prices beyond the actual increase.
Case study
Seen in the real world.
This is an illustrative story about a fictional business, Northstar Marine Leasing, which owned twelve ageing cargo ships. A new international rule on emissions and fuel quality was due to take effect in two years, and the older ships would need expensive upgrades or earlier retirement.
The CFO modelled three options. She could retrofit all twelve ships, retire the four oldest and retrofit the rest, or sell the whole fleet, and she compared the cash flows and the effect on the company's covenants. Each option was tested against low and high fuel price assumptions.
The board chose to retire the four oldest vessels and retrofit the remaining eight, financing the work with a green loan priced slightly below the company's usual rate. The illustrative case shows how a global rule can reshape asset values, capital spending and funding decisions well before it comes into force.
Watch out
Common mistakes.
- Assuming the IMO enforces its own rules. Flag states and port states carry out inspections and penalties.
- Ignoring regulation when valuing a ship. A vessel that cannot meet upcoming rules may lose value faster than its age suggests.
- Treating compliance costs as one-off. Regulations are updated regularly, and fuel, equipment and reporting costs can recur, so they belong in the multi-year forecast.
Questions
People also ask.
What does the IMO regulate?
Shipping safety, security, pollution prevention, crew training and, increasingly, the greenhouse gas emissions of vessels.
Why does it matter to non-shipping businesses?
Because freight and insurance costs flow through to the price of goods, so rule changes can reach importers and exporters.
Who has to follow IMO rules?
Governments that sign up to its conventions must apply them, and ship owners and operators must comply with the national laws that implement them.
