The claim is strongly supported by multiple independent search observations pointing to the IMF publication 'Tokenized Finance - International Monetary Fund' and its eLibrary counterpart. Search snippets for both sources explicitly say tokenization is 'increasingly shaping' the financial system and that 'the most consequential transformation is occurring within the regulated financial system, including banks, asset managers, and financial market infrastructures.' That wording closely matches the user's statement that the IMF says tokenisation is reshaping regulated finance. Additional IMF materials, including 'What Is Tokenization? - International Monetary Fund' and 'Tokenization and Financial Market Inefficiencies - International Monetary Fund,' provide consistent institutional context. Confidence is not high only because direct web_fetch retrieval of the cited IMF pages and the X links failed in this run, so the strongest sources could not be fully validated from fetched page content.
