Global yields often move together because major economies share inflation shocks, growth cycles, capital flows and expectations about central-bank policy.
THE MECHANISM
What is happening underneath
Investors also compare yields across countries and hedge positions internationally.
MARKET INTERPRETATION
How investors should read it
Domestic fiscal, currency and policy differences prevent the relationship from being perfect.
BONDSTATS TAKEAWAY
