S&P Dow Jones Indices Announces Renaming of the iBoxx Leveraged Loan indices and the S&P UBS Liquid Leveraged Loan indices

S&P Dow Jones Indices (“S&P DJI”) is pleased to announce that the iBoxx Leveraged Loan indices and the S&P UBS Liquid Leveraged Loan indices will be renamed effective Monday, October 1, 2025. This renaming will align the iBoxx Leveraged Loan indices with the previously announced integration of the S&P UBS Leveraged Loan indices into S&P DJI’s index offering. As part of this process, the affected indices’ names and references to those indices on the S&P DJI website and within their index methodologies will change as more particularly described below. 

 

  1. Renaming of the iBoxx Leveraged Loan indices, including the Markit iBoxx USD Liquid Leveraged Loan index

The iBoxx USD Leveraged Loans index and its sub-indices will be renamed by replacing ‘iBoxx USD Leveraged Loans’ with ‘S&P UBS USD Broad leveraged Loan’. The Markit iBoxx USD Liquid Leveraged Loan index will be renamed to S&P UBS USD Liquid Leveraged Loan index.

  • The attached file contains the list of iBoxx indices that are being renamed including both the existing and planned updated index names. 
  • The name of the index methodologies and references to these indices in the corresponding methodologies will also change effective October 1, 2025:
    • Old: iBoxx USD Leveraged Loan Index Methodology → New: S&P UBS Broad Leveraged Loan Index methodology
    • Old: iBoxx USD Liquid Leveraged Loan Index Methodology → New: S&P UBS Liquid Leveraged Loan Index methodology

 

  1. Renaming of the S&P UBS Liquid Leveraged Loan indices

In addition to the rebranding described in 1 above, the S&P UBS Liquid Leveraged Loan index and its subindices will be renamed by replacing ‘Liquid’ with ‘LargeCap’. That is, the S&P UBS Liquid Leveraged Loan Index will change its name to S&P UBS LargeCap Leveraged Loan index. References to the indices on the S&P DJI website and in the S&P UBS Leveraged Loan index methodology (‘S&P UBS Leveraged Loan Index Methodology’) will also change effective October 1, 2025. The attached file contains the list of S&P UBS Liquid Leverage Loan Indices that are being renamed, including both the existing and planned updated index names.

 

  1. The following additional details apply to the renaming implementation 
  • Packages
    • Existing index data packages will remain unchanged and client access to such packages will be unaffected by the name change.
  • Files
    • Within S&P DJI’s index data files, only the index names will change. These changes are scheduled to be implemented as follows: 
      • Files produced up to and including Sunday, September 30, 2025, will contain the existing index names. 
      • Files produced on Monday, October 1, 2025, will contain the new updated index names.
    • There will be no changes to the index codes, index keys, index tickers and other index identifiers.

 

  • Other Information
    • The index methodology, rebalancing and calculation processes for the indices remain unaffected by this change. 
    • Methodologies, website, and marketing content is expected to be updated by the opening of Monday, October 1, 2025.

Many of the indices are on vendor platforms. S&P DJI will be notifying those platforms of the updates to the index names, so we expect the platforms to reflect also the new names as early as Monday, October 1, 2025, but renaming remains subject to redistributors’ ability to make timely updates.
