Fair Value Disclosures [Abstract]  
Fair Value Fair Value
The assets and liabilities that GATX records at fair value on a recurring basis consisted entirely of derivatives at March 31, 2026 and December 31, 2025.

In addition, we review long-lived assets, such as operating assets and facilities, investments in affiliates, and goodwill, for impairment whenever circumstances indicate that the carrying amount of these assets may not be recoverable or when assets may be classified as held for sale. We determine the fair value of the respective assets using Level 3 inputs, including estimates of discounted future cash flows, independent appraisals, and market comparables, as applicable.

Derivative Instruments

Fair Value Hedges

We use interest rate swaps to manage the fixed-to-floating rate mix of our debt obligations by converting a portion of our fixed rate debt to floating rate debt. For fair value hedges, we recognize changes in fair value of both the derivative and the hedged item as interest expense. We had one instrument outstanding with an aggregate notional amount of $50.0 million as of March 31, 2026 that matures in 2027 and one instrument outstanding with an aggregate notional amount of $50.0 million as of December 31, 2025 that matures in 2027.

Cash Flow Hedges

We use U.S. Treasury rate locks, swap rate locks, and interest rate swaps to hedge our exposure to interest rate risk on anticipated transactions. We also use currency swaps, forwards, and put/call options to hedge our exposure to fluctuations in the exchange rates of foreign currencies for certain loans and operating expenses denominated in non-functional currencies. We had fifteen instruments outstanding with a notional amount of $1,763.0 million as of March 31, 2026 that mature in 2026 to 2030 and three instruments outstanding with a notional amount of $2,370.6 million as of December 31, 2025 that each mature in 2031. Within the next 12 months, we expect to reclassify $5.3 million ($4.8 million after-tax) of net losses on previously terminated derivatives from accumulated other comprehensive loss to interest expense. We reclassify these amounts when interest and operating lease expense on the related hedged transactions affect earnings.

Non-Designated Derivatives

We do not hold derivative financial instruments for purposes other than hedging, although certain of our derivatives are not designated as accounting hedges. We recognize changes in the fair value of these derivatives in other income (expense) immediately.

Certain of our derivative instruments contain credit risk provisions that could require us to make immediate payment on net liability positions in the event that we default on certain outstanding debt obligations. The aggregate fair value of our derivative instruments with credit risk related contingent features that were in a liability position was $11.2 million as of March 31, 2026 and $28.5 million as of December 31, 2025. We are not required to post any collateral on our derivative instruments and do not expect the credit risk provisions to be triggered.

In the event that a counterparty fails to meet the terms of an interest rate swap agreement or a foreign exchange contract, our exposure is limited to the fair value of the swap, if in our favor. We manage the credit risk of counterparties by transacting with institutions that we consider financially sound and by avoiding concentrations of risk with a single counterparty. We believe that the risk of non-performance by any of our counterparties is remote.

We value derivatives using a pricing model with inputs (such as yield curves and foreign currency rates) that are observable in the market or that can be derived principally from observable market data. As of March 31, 2026 and December 31, 2025, all derivatives were classified as Level 2 in the fair value hierarchy. There were no derivatives classified as Level 1 or Level 3.

Other Financial Instruments

Except for derivatives, as disclosed above, GATX has no other assets and liabilities measured at fair value on a recurring basis. The carrying amounts of cash and cash equivalents, restricted cash, rent and other receivables, accounts payable, and borrowings under bank credit facilities with maturities under one year approximate fair value due to the short maturity of those instruments.

We estimate the fair values of fixed and floating rate debt using discounted cash flow analyses that are based on interest rates currently offered for loans with similar terms to borrowers of similar credit quality. The inputs we use to estimate each of these values are classified in Level 2 of the fair value hierarchy because they are directly or indirectly observable inputs.
