I believe the answer is:

renminbi

I'm a little stuck... Click here to teach me more about this clue!

'money overseas' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'desperate northern miner swinging both ways' is the wordplay.
'desperate' indicates anagramming the letters (a desperate or pathetic spelling).
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'swinging both ways' becomes 'bi' (short for bisexual).
'n'+'miner'='nminer'
'nminer' with letters rearranged gives 'renmin'.
'renmin'+'bi'='RENMINBI'

'for' is the link.

Can you help me to learn more?

(Other definitions for renminbi that I've seen before include "payment in China?" , "change in China" , "money in China" , "Nine brim with Chinese currency" .)
