What it does
Net Interest is Marc Rubinstein's English-language newsletter about the financial sector. It examines institutions, financing arrangements and business developments through extended essays.
A story connecting AI investment with financing gives readers a route from a technology headline into the arrangements supporting it. The company and institution-focused essays suit a sustained business reading project. Net Interest is sent as a weekly email. Paid readers unlock the paywalled portion of each issue, the searchable archive and exclusive Net Interest Extra podcast episodes.
