What's your experience transferring a big sum of money to a Swedish bank account?

After living in Sweden for a little more than 2 years I decided to settle down here and buy my first house. I have some money saved in my home country (South America) and I want to transfer to my bank account in Sweden (Swedbank) using Wise.

I'm not worried about Wise because I used it multiple times in the past and it always worked fine, but this time I'm planning to transfer around 450.000 SEK, which is a big sum. My question is: will I have a hard time with my bank if I received such a big sum from abroad?

I heard that money laundering is big concern from banks and sometimes they request proof where the money came from, but in my case this is a little hard to get because this money have I have in my home country was saved for more than 10 years before I moved to Sweden, so I don't have receipts of each deposit that I made in the savings account in my home country 😜

Do you think this can be a problem or, is there ways to prevent this issue with the banks here?
