Pledged Assets. As part of its liquidity management strategy, Northern Trust may pledge loans and/or securities to various financial market utilities to allow for client payment, clearing and settlement processing as part of our custody services. Northern Trust may also pledge loans or securities to Central Banks, Federal Home Loan Bank (FHLB) of Chicago and third parties for various purposes, for example: securing public and trust deposits, repurchase agreements, borrowings and derivative contracts.

Restricted Assets. Certain cash may be restricted in terms of usage or withdrawal. As a result of the continuing military conflict involving Ukraine and the Russian Federation and related sanctions and legal restrictions in place, cash balances denominated in Russian rubles received for the benefit of certain clients in our Asset Servicing business are subject to distribution restrictions. As of September 30, 2025 and December 31, 2024, these balances totaled $1.5 billion and $1.1 billion, respectively, and are reported in Cash and Due from Banks on the consolidated balance sheets.
At September 30, 2025 and December 31, 2024, Northern Trust held cash of $520.0 million and $491.2 million, respectively, to meet non-U.S. reserve requirements. The Federal Reserve’s U.S. reserve requirement is zero percent. As a result, there were no average deposits required to meet Federal Reserve Bank reserve requirements for the three and nine months ended September 30, 2025 and 2024, respectively.
