After the end of a month or quarter, the portfolio manager exports Euroclear account statements and internal accounting data into Excel, calculates the period return and fees, places them in the report template and then writes the cover letter, in English, German or another language depending on the client. Some firms have the same data in Power BI reports, but the letter is still written by hand. With dozens of clients, that is a week of work in which it is easy to mix up the period or the currency or to paste another client's table. The text is often copied from the previous month, and before sending, the compliance officer checks that no accidental assessment or promise has crept into the letter.
The agent works on a schedule. With read-only permissions, it takes each client's portfolio holdings and transactions from the Euroclear statement export, and returns and fees from your Excel or Power BI reports, places them in a report template approved by compliance and writes a cover letter in the client's language. The letter describes facts: what changed, which transactions took place, which fees were applied. No assessments, forecasts or suggestions; recommendations are given only by licensed people. Claude runs in Amazon Bedrock in an EU region, and client data is not used for training. The portfolio manager receives the draft in Outlook or on the client record in Salesforce, reviews the figures, adds a personal comment and only then does the letter go to the client. We connect to Euroclear and accounting through file export or an API, depending on your version. Sending and every change stay in the log.
