Financing environment
The consistent view from participants in our interviews was that the aviation debt market had matured and is in rude health.
The interest cuts by the US Federal Reserve in 2025 gave real momentum to the financing markets as spreads tightened. The historic close link between interest rates and lease rate factors was disrupted in 2025 as aircraft shortages kept lease rates strong, despite falling spreads.
As well as cost, diversification of funding sources and matching maturities remains critical for the industry. Aviation continues to source funding from the unsecured capital markets, the structured product market, traditional banks, alternative lending / credit funds, as well as more niche products such as sukuks and Japanese equity.
These financing markets are open and actively seeking aviation exposure. With the industry delivering over US$100bn of aircraft in 2025, with an anticipated increase to US$125bn in the near term, diverse and deep sources of capital are essential.
An investment grade rating remains critical to the competitive position of large aircraft lessors and for certain airlines, allowing access to deep pools of efficient capital that remain available even during periods of turbulence.
The growth in the number of investment grade lessors is consistent with the evolution and increasing maturity of the aviation leasing market, with a number of aviation lessors benefiting from rating upgrades in 2025 and speculation surrounding further potential upgrades in 2026.
The appetite of the traditional banking market remains resilient, benefiting from a favourable regulatory environment in the US and the emergence of some new bank lenders as new equity investors in aviation are able to access their existing local banking relationships to raise capital in regions such as the Middle East and Asia.
For structured products, the aviation ABS market surged back in 2025 with US$10bn of debt issuances, which could hit record levels in 2026 if conditions remain stable. While there have been secondary trades of aviation ABS E-notes, primary issuances have been slower to return but there is growing confidence that a primary issuance of aviation ABS E-notes will happen in 2026.
The aviation loan ABS market also continues to grow as alternative lenders fund gaps in the aviation financing market and become an additional pillar of the capital stack.
Sustainable financing took a back seat in 2025 but is acknowledged as a key long-term industry trend that will re-emerge.
