A closer look

There is a square mile in London where the king once needed permission to enter his own city. The City of London, the old financial district, evolved into a semi-autonomous entity with its own rules, governance, and immense economic power. For centuries, a ritual required the monarch to stop at the boundary and be greeted by the Lord Mayor, symbolizing that even the crown could not simply stroll in unannounced. Today, this tiny area remains a global banking hub with structures and privileges that outlived empires. Its strange status is a reminder that money can carve out sovereignties inside nations, bending laws and traditions around itself. When people talk about markets ruling states, they often do not realize there is a physical place where that metaphor was almost literal.
