Container Leasing

Container leasing is the business of renting shipping containers to ocean carriers, and sometimes to shippers and freight companies, instead of the users buying the boxes themselves. Specialist lessors buy new containers from manufacturers, mostly in China, and rent them out for a daily charge known as the per diem. The lessee uses the box as if it were its own, then returns it at an agreed depot when the lease ends.

Leasing sits alongside owning as one of two ways a carrier builds its fleet. As of the end of 2024, lessors owned about 48 percent of the world's container fleet, according to Triton International, the largest lessor. Container leasing is a form of operating-asset finance and should not be confused with ship chartering, which rents whole vessels.

Think of a car rental company at an airport. Travellers could buy a car in every city they visit, but it is cheaper and simpler to rent one when needed and hand it back afterwards. The rental firm owns a huge fleet, spreads the cost over many customers and deals with repairs.

Shipping lines use leasing companies in the same way. A carrier that suddenly needs thousands of extra boxes for a busy season can rent them instead of tying up money in buying them. When trade slows, it returns some, and the leasing company rents those boxes to someone else.

Lessors offer several contract forms, which differ in length, price and flexibility:

• Long-term leases. These usually run for five to eight years or more at a fixed per diem, and make up most of the large lessors' business.
• Finance leases. The lessee pays for the box over the lease term and normally ends up owning it, so the arrangement works much like a loan secured on the equipment.
• Service or master leases. A master agreement lets the carrier pick up and drop off boxes as needed at agreed depots, at a higher per diem in exchange for the flexibility.
• Sale-leasebacks. A carrier sells containers it owns to a lessor and rents them back, freeing cash for other uses.

Service leases often carry pick-up credits where boxes are scarce and drop-off charges where they are surplus. These prices are a direct way of passing the cost of empty container repositioning back to the lessee.

A simple way to view a lessor's income from one box is:

• $R$ is the annual lease revenue from one container.
• $p$ is the per diem rate.
• $u$ is the utilization rate, the share of days the box is on hire, written as a decimal.

Dividing $R$ by the purchase price $P$ gives a rough annual yield on the box, before depreciation, repairs and financing costs. In an illustrative case, a 20-foot box bought for $2,200 and leased at $0.80 a day with 97 percent utilization earns $0.80 \times 365 \times 0.97 \approx 283$, or about $283 a year, a gross yield of $283 \div 2{,}200 \approx 12.9\%$. Because a container's working life at sea is typically 12 to 15 years, the lessor's return also depends on what the box fetches when it is sold for storage or other uses.

The industry is concentrated among a handful of firms, several of which changed hands in the 2020s:

• Triton International. The world's largest lessor, with a fleet of about 7.0 million TEU at the end of 2024; it was acquired by Brookfield Infrastructure in September 2023.
• Textainer. Acquired by the infrastructure investor Stonepeak in March 2024, in a deal valuing the company at about $7.4 billion including debt.
• CAI International. Bought by Japan's Mitsubishi HC Capital in November 2021.
• Florens. A leasing arm of China's state-owned COSCO Shipping group.

The move of these companies into infrastructure and private equity portfolios reflects investor interest in long-lived assets with contracted income. Lessors fund purchases largely with debt, so interest rates and capital allocation decisions strongly affect their margins, and lenders watch measures such as EBITDA when setting terms.

Carriers lease for flexibility and balance-sheet reasons. Box demand swings with international trade, and leasing lets a line add or shed equipment without owning a fleet sized for the peak. Lessors' scale gives them economies of scale in buying, repairing and reselling boxes, and their global depot networks let carriers return boxes where they are surplus. Leased boxes also make street turns and pooling easier, since several users can share one stock.

Leasing carries risks for both sides. Lessors face falling utilization in downturns, when carriers return boxes and new-build prices drop, as well as the credit risk of a lessee failing, as happened when Hanjin Shipping collapsed in 2016 and lessors had to recover containers worldwide. Lessees face per diem costs that keep running while a box is idle, so long dwell time at ports or customers raises the true cost per trip, much as demurrage does for cargo owners. Contracts therefore spell out return locations, damage standards and the replacement value payable if a box is lost.
