Some updates on TMT finance

This article updates the series of articles published between March 2015 and November 2018 on the subject of financing businesses in the TMT sectors (Series 1). Since then, the type and value of intangible assets have increased, many banks have launched growth debt products, private credit firms have expanded their business both generally and in providing credit to technology  businesses, and some legal developments relevant to intangible assets and credit finance have taken place.
Certainly, the value of the market has grown. According to the latest ONS figures (published in November 2024), in 2022 UK businesses invested £200bn (a record) into intangible assets. This statistic also illustrates one of the original points of Series 1: of the £200bn, only around half was invested in assets protected by intellectual property rights (IPR); the rest paid for assets such as know-how, trade secrets, business processes, and all the other intangible assets that are not covered by IPR.
We can view the lay of the land in 2025 by considering what has not changed, what has changed, and what is changing.

Towards algorithm auditing in financial services

We are witnessing a rapid development and adoption of algorithms. At the same time, we need to develop the monitoring and managing of their safety. In the algorithmic age companies are (and should be) increasingly concerned about potential harm that their systems can cause, both in terms of reputation and financially. Knight Capital’s experience (~$450m) caused by a glitch in its algorithmic trading system is a paradigmatic example. As such, in addition to societal, legislative and regulatory pressures, companies themselves are keen to assure their systems are trustworthy.1

Artificial intelligence in syndicated lending

AI adoption and deployment forms part of this anticipated spend. Alongside AI, tokenisation of debt instruments will create a new model in syndicated loan markets. This article explores the current position on AI in syndicated lending.
