Hello,
What would we say when speaking about a bank, that it's a firm or a company

Thanks

 

That's a bank! Seriously, most of the time, a bank is referred to as... a bank. If private, I guess you could call it a "company".

 

I think that banks are institutions, or establishments.

 

I doubt whether firm could be used.
It would usually be a business organisation or company. If it has plc or ltd (UK terms) after the name (e.g. Lloyds Banking Group plc) then it is definitely a company.

 

'Firm' is commonly used for any company, but more strictly a firm is a limited partnership, like a firm of solicitors or of accountants, where each partner is a shareholder and it is not publicly owned.

 

Just to add that Lloyds Banking Group plc is not a bank but the company that directs (or has ownership of) the numerous subsidiary companies of the group, the most well-known of which is probably "Lloyds Bank" which is a bank.

 

Thank you all, I'll use "company" because it is a public economic bank

 

A bank, as normally used, is a local office or branch of a company. The term bank does not mean a company per se.
The Bank of England, for example, may well be a company, but it is not a bank in the ordinary sense of the word.
