Bit of a click bait headline for such a mundane topic
You’ll be back when you remember how bad the other banks suck. I do regular bank switches and part of that involves pretending to be a customer for up to a year to get full bonuses. I can confirm they are all still terrible and Monzo is much better.
The cause of your rejection could be Monzo re-writing their lending criteria (which all banks do all the time depending on how much they want to lend at any point in time), or it could be you.
There are also loads of things that can make your credit score drop (by credit score I mean your actual desirability to a lender when they analyse your credit reports, rather than a ‘shot in the dark’ number given by Experian). A recent change of address / no electoral roll info, more than one or two recent credit searches, slow account updates meaning the report could show account balances that are out of date, a change in salary etc - just a few of the million reasons a lender might change their mind about offering a line of credit.
Monzo have not offered loans for very long and you have already successfully paid off 2 and had an overdraft as well. Just speculating (as you were) but maybe you are making a lot of credit applications and this is affecting your scores and desirability to lenders? Have you tried applying elsewhere to see if it is just Monzo rejecting you or if it’s orhers too?
I’ve never been offered a Monzo overdraft or loan and I think they are very cautious lenders, which is a good thing when the tabloids are very eager to paint them as the new Wonga.
