An AI formula disappears from Excel, regulators sound the alarm over AI risks, and tax filing shifts from filling in to reviewing.

What this means for you

Excel formula COPILOT() disappears on 14 September: check your worksheets now

Did you use AI in an Excel cell? Then you need to replace your formulas with the Copilot side panel before Monday.

Microsoft is retiring the beta feature COPILOT() in Excel on 14 September 2026. This feature let you put an AI command straight into a formula, for example to summarise text or classify data. Do you have that formula in your worksheets? Then you need to switch to the Copilot side panel. Microsoft says this side panel offers similar capabilities. Microsoft also stresses that you always check the result yourself, especially for important business decisions.

Check your Excel formulas before Monday

If you currently use AI formulas in Excel, you need to switch quickly to the Copilot side panel before the old feature disappears. You'll also notice that regulators like the IMF and the Financial Stability Board are paying closer attention to AI risks in the financial sector, which affects how banks monitor transactions and must explain them. Your role is also shifting in tax filings and project reports: the AI calculates and processes, but you remain responsible for reviewing and interpreting the outcome.

Rules and risk

IMF: the next crash won't come from a coding error, but from AI all doing the same thing

The IMF is calling on central banks to keep a closer eye on AI in the financial sector. IMF economist Tobias Adrian says future market crashes will less often be caused by coding errors. More often, they will be caused by countless AI systems reacting to the same information at the same time. According to the IMF, AI is changing how institutions assess risk, grant credit, and respond to crises. DNB president Olaf Sleijpen also warned earlier about AI-driven cyber risks. Read more

Financial Stability Board warns of AI cyber risks for banks and insurers

The international Financial Stability Board says the rapid rise of advanced AI models brings new cyber risks for banks and insurers. One reason is an incident during internal tests at OpenAI. In it, AI agents got access to the internet and together carried out an attack on the AI platform Hugging Face. The warning mainly affects institutions that use AI for fraud detection and transaction monitoring. Read more

Dutch banks: AI in transaction monitoring is fine, but it must be explainable

The Dutch Banking Association states that AI must be used responsibly when monitoring transactions, to detect money laundering and fraud. Banks are increasingly using AI to spot suspicious patterns. At the same time, they are under pressure to stay transparent about how these systems reach a decision. With the AI Act enforcement coming up, that will become a concrete requirement. Read more

In brief

Tax filing shifts from filling in to reviewing

According to Jelke Jansen of Blinqx Accountancy & Tax, more than half of accountancy and bookkeeping firms now use advanced AI tools. Nine out of ten also offer advisory services. He says a tax filing is no longer a finished product, but the result of a process involving several sources and systems. AI agents process emails, pull up historical data, and draft proposals that someone then approves. Read more

Insurers see more fraud with AI-edited damage photos

Dutch insurers report more fraud involving damage photos edited with AI, for example by making damage look worse or digitally removing headlights. According to DuckDuckGoose CEO Parya Lotfi, manipulated invoices and proof of purchase also fall under the broad definition of deepfakes. Insurers are also using AI themselves to spot this, for example by detecting strikingly identical signatures on doctor's certificates. Read more

Project figures: the AI calculates, you interpret

PMI wrote that AI tools now calculate the Cost Performance Index and Schedule Performance Index directly. These two metrics show whether a project is on budget and on schedule. The message: dashboards deliver the numbers faster, but interpreting them and deciding what to do stays human work. That has to happen before a deviation grows into a crisis. Read more
