Every December I try to separate the signals that deserve a line in next year's plan from the noise that deserves a watching brief. The last quarter of 2025 was unusually rich in signals, because several long-running debates turned into concrete rules, charters and standards.

Each shift below carries a signal strength: how clearly the evidence already points in one direction, not how important I think the theme is. Five means the direction is set in rules or deals already announced; three means the direction is clear but the timing and scale are not. Where I have written about a shift in more depth, the link takes you to the analysis.

The common thread is that 2026 is less about new technology and more about who carries the risk. Stablecoin rules decide who bears liquidity risk; fraud reform decides who bears scam losses; charters decide who is supervised for custody; and agentic commerce will decide who is accountable when software spends a customer's money. Plan for the risk transfers, and the technology choices get easier.
