Question 1

How much purchasing power does 100 GBP in London represent in New York?

Accepted Answer

Per World Bank PPP, 100 GBP in London (United Kingdom) has roughly the same spending power as 151 USD in New York (United States). This isn't a bank exchange rate — it's "how much local currency you'd need for the same standard of living".

Question 2

Why is this different from the exchange rate?

Accepted Answer

Bank rates reflect currency markets; PPP reflects domestic goods and services prices. The two often diverge meaningfully, especially between developed and developing economies.

Question 3

How accurate is the London–New York comparison?

Accepted Answer

World Bank PPP data is country-level, so the same figure applies to every city in a country. London stands in for United Kingdom and New York for United States. Monthly refresh with a 12-18 month publication lag.
