What this hub covers
Each country hub separates the financial system from the companies operating on
top of it. That means central banking, supervision, deposit protection, clearing and
settlement first; payment and data infrastructure second; regulated firms and their
economics third.
It deliberately avoids generic “best app” lists. The goal is durable country
intelligence: who controls the rails, where firms make money, what protection applies,
and which operational or regulatory constraints determine whether growth lasts.
