The Global Liquidity Scorecard uses 27 currencies as denominators.
USD is the default starting point. EUR, GBP, JPY, CAD, CHF, AUD, CNY for the majors.
Then 20 more across Asia Pacific, the Middle East, and Latin America. KRW, INR, BRL, MXN, SAR, AED, TRY, IDR, and others.
The same liquidity composite reads differently in different currencies, and a trader operating in Brazil or Saudi Arabia benefits from the local currency view rather than the default USD one.
The world is GLOBAL, and as such, it is critical to track liquidity across the major markets, and not just with a US-centric mindset.
