300 billion euros of European savings leave Europe due to unattractive capital markets.

• The Letta report uses the qualifier 'around' (environ) — the figure is an estimate, not a precise statistical measurement from an official statistical agency like Eurostat or the ECB.
• The original source is the Letta report published in April 2024, now over two years old relative to the June 2026 session date. More recent data confirming or updating this figure was not identified in available searches.
• The claim attributes the outflow solely to 'unattractive capital markets,' but the Letta report identifies multiple structural causes — including regulatory fragmentation across Member States, lack of a unified supervision framework, and underdeveloped venture capital and equity markets — not merely the attractiveness of returns.
• The outflow is overwhelmingly directed to the United States specifically, a detail omitted from the claim which speaks generally of 'leaving Europe.'
