German city bank welcoming reforms at first (5)
I believe the answer is:
trier
'german city' is the definition.
(Trier is a city in Germany)
'bank welcoming reforms at first' is the wordplay.
'bank welcoming' becomes 'trie' (I can't justify this - if you can you should give a lot more credence to this answer).
'at first' indicates taking the first letters.
The first letter of 'reforms' is 'r'.
'trie'+'r'='TRIER'
Can you help me to learn more?
(Other definitions for trier that I've seen before include "One who refuses to give up -- German city on the Moselle" , "one never giving up" , "town in Germany" , "conscientious type?" , "One has a crack" .)
