As collateralized loan obligation (CLO) markets continue to gain traction across institutional and retail channels, Northern Trust is expanding its middle office services to meet growing operational complexity. The bank announced enhancements to its Omnium platform, adding compliance indenture monitoring and waterfall calculation functionality designed to support the full CLO lifecycle. 

The expanded offering builds on Omnium’s structured debt capabilities, which already include loan closing, treasury services and real-time data sharing. Under a rules-based framework, the platform now monitors key CLO indenture tests such as concentration limits, credit rating thresholds, interest coverage ratios, over-collateralization levels and collateral quality requirements. 

“By automating compliance monitoring and waterfall oversight within the same infrastructure used for middle office operations—and delivering timely, actionable insights—we enable asset managers and CLO participants to operate at scale, streamline workflows, and mitigate risk more efficiently,” said Nadia Cobalovic, global head of Omnium Services and Total Portfolio Solutions at Northern Trust. 

The expansion comes as CLO issuance and investor participation broaden, including increased activity in CLO exchange-traded funds from traditional managers like Fidelity Investments and Janus Henderson. 

As of December 31, 2025, Northern Trust reported $18.7 trillion in assets under custody and administration and $1.8 trillion in assets under management.
