You need an EMI has crypto wallet and fiat wallet together. Kraken BTC -> Wirex BTC wallet -> Exchange (1%) to any currency EUR, GBP... and use the fiat wallet of Wirex to transfer to your bank account.
There are many ways of doing it, your bank may just has already blacklisted major exchanges Kraken, Coinbase, Bitfinex , Luno. etc.. You can use a not so well known exchange with fiat walllet and try transfer to your bank. If that works good for you.
You can try Wirex, SpectroCoin, since they can exchange BTC internally .. and your bank doesnt sees them as crypto exchange.︀ (Of course it comes with a fee, they need to make money too right)
Just my 2 cents.
