Lease vs loan aircraft finance compared

Lease vs loan aircraft finance distinguishes structures in which an airline (or affiliate) borrows and mortgages an aircraft from structures in which a lessor owns the aircraft, leases it to the operator, and finances ownership through debt secured on the asset and lease cash flows. Both paths can create Cape Town international interests and both appear in officially supported export credit packages.

Lease vs loan aircraft finance under Cape Town

The Cape Town Convention defines an international interest as an interest in a uniquely identifiable aircraft object that is granted by a chargor under a security agreement, vested in a conditional seller under a title reservation agreement, or vested in a lessor under a leasing agreement. Applicable law determines which category applies.

A loan financing typically uses the security agreement path: the owner chargor grants a mortgage or charge to the lender. A leasing financing uses the lessor's vested interest under the leasing agreement as an international interest, often combined with a mortgage granted by the owning lessor to its financiers. ICAO describes the Convention and Aircraft Protocol as addressing divergent national treatments of securities, title retention and leases that otherwise raise financing costs for airframes, engines and helicopters.

Registration in the International Registry perfects priority for the relevant international interest in Contracting States. The economic label lease or loan does not by itself determine Convention category; the documented rights do.

EXIM's published preference for finance lease structures

US EXIM states that it lends, or guarantees a loan by a financial institution, to a special purpose entity that then leases the aircraft to the airline, or in certain exceptional circumstances to the airline. The SPV finance lease path is therefore the standard published structure, with direct airline borrowing treated as exceptional.

EXIM's credit decision, as published, rests on airline or lessee creditworthiness and any guarantor, plus security from the finance lease structure, a first priority mortgage on the financed aircraft, and other risk mitigants. In that model:

• the SPV owns the aircraft and is the borrower under the EXIM supported loan or guaranteed loan
• the airline is the lessee and pays rent that services the SPV's debt
• lenders hold a first priority mortgage on the aircraft and rights over lease rentals as part of the security package

A direct loan to the airline would place the mortgage and payment obligation with the airline as owner borrower. EXIM's materials mark that route as exceptional, signalling that asset isolation in an SPV lessor is the default official support path for many transactions.

Economic and credit differences

Under a loan to the airline owner, debt service is a direct corporate or ring fenced airline obligation secured by the aircraft mortgage and related assignments. Covenant packages, maintenance reserves and insurance requirements attach to the airline borrower. Title sits with the airline subject to the mortgagee's security interest.

Under a finance lease through an SPV, title sits with the lessor SPV. The airline's payment obligation is rent under the lease. Lenders look to lease assignment, SPV insolvency remoteness, mortgage enforcement and airline lessee credit. Residual value and end of lease purchase options, where present, allocate ownership economics between lessor and lessee according to the lease.

Operating leases used in commercial aviation place residual value and ownership risk more clearly with the lessor. Cape Town still recognises the lessor's international interest under a leasing agreement when Convention conditions are met. Official export credit under the Aircraft Sector Understanding more commonly aligns with finance lease or loan purchase structures for new manufacturer deliveries than with pure operating lease lessor programmes, subject to product eligibility.

OECD Arrangement and ASU context

The OECD Arrangement treats officially supported export credits for civil aircraft under the Aircraft Sector Understanding (Annex III). Official support may take the form of export credit guarantee or insurance, official financing support including direct credit or financing and refinancing or interest rate support, or a combination. Those forms can attach to either a loan to an airline or a loan to a lessor SPV, provided the export and eligibility conditions of the ASU and the supporting export credit agency are met.

EXIM's published ASU constrained terms, including a maximum repayment tenor of twelve years for supported aircraft financing and amortisation to zero on level principal or mortgage style schedules, apply to the EXIM supported debt regardless of whether the borrower is the exceptional airline borrower or the standard SPV lessor.

Documentation map for credit desks

In a loan to the airline owner, the airline or an airline owned company holds title, pays loan debt service, and grants a security agreement mortgage that can be registered as an international interest. In a finance lease via SPV, the lessor SPV holds title, the airline pays rent, and lenders typically take both the lessor's Cape Town interest path and a mortgage over the aircraft. EXIM's published path treats the SPV lease as standard and the direct airline loan as exceptional.

A complete credit file records the borrower, the owner, the Cape Town category of each registered interest, the mortgagee, the source of debt service cash, and any residual value or purchase option that changes end of term economics. Lease vs loan aircraft finance is a structural choice about title, payment path and insolvency isolation, not a change in the underlying need for first ranking asset security and enforceable international interests.

Desk summary

Lease vs loan aircraft finance turns on whether the airline owns and mortgages the aircraft as borrower, or leases from an SPV that borrows against the asset and lease. Cape Town covers both security agreement and leasing agreement interests. US EXIM's published aircraft product centres on the SPV finance lease with a first priority mortgage, treating direct airline loans as exceptional.
