Why do we need new designs, exactly? Never mind that I rarely look at my money closely enough to care all that much what it looks like.
I’m assuming they are updating the security features to make them as counterfeit-proof as possible. Giving them a new design makes it easier to tell the old ones and the new ones apart.
That would be an explanation I could accept. Would be nice if Mme Lagarde said anything to that effect in the video.
I have to admit that I didn’t watch the whole video, I just assumed based on the last redesign. But I looked into it and apparently there are several reasons besides security reasons, among them making the banknotes more sustainable and environmentally friendly.

The European Central Bank (ECB) is the central bank of the European Union countries which have adopted the euro. Our main task is to maintain price stability in the euro area and so preserve the purchasing power of the single currency.

Thank you for the link. Whatever the reason, I would appreciate if she mentioned it, even in passing, instead of making viewers dig for more information.
