As the year winds down, Banking Dive is highlighting a cross-section of coverage we think is among our best.

We often look at challenges to legacy banks posed by technology-driven upstarts. But over the past couple of months, developments — at least twice — have forced us to ask: What happens when the challenge comes from well-established players (like Walmart or, potentially, Twitter)?

We examine the landscape of new business opportunities, such as banking-as-a-service and cannabis, and the regulatory challenges that executives face.

We look at regulators, too. The Federal Reserve Board, for example, looks vastly different from a year ago, and we dive into the dynamics of oversight to see how it might change.

We follow the ups and downs of the crypto sphere — and have developed a handy tracker to follow the rash of executive departures some platforms have seen in past months.

We explore long-standing debates, too — such as the politics of office returns and how the workplace has changed as the COVID era wraps up its third year.

We hope this collection of pieces serves you well.
