Inflation sits at the heart of modern currency moves because it dictates what central banks do with interest rates. Understanding CPI and ڕاستەقینە yields explains much of what drives FX.
CPI and why it matters
The Consumer نرخ Index (CPI) measures inflation. بەرز or rising inflation pressures central banks to raise rates (often currency-supportive); falling inflation gives room to cut. CPI releases are among the highest-impact events on the کالێندەر.
ڕاستەقینە yields
A nominal yield minus inflation gives theڕاستەقینە yield— the true return after inflation. Currencies often follow ڕاستەقینە yields: a country with بەرز nominal rates but even higher inflation may have a weak ڕاستەقینە yield, and a weak currency. Nominal numbers can mislead; ڕاستەقینە yields tell the deeper ستۆری.
Putting it together
The chain is: inflation data → rate expectations → ڕاستەقینە-yield shifts → currency moves. Watching how a CPI surprise changes the expected path of rates explains why a currency reacts the way it does, sometimes counter to the headline.
Key takeaways
- CPI measures inflation; surprises strongly shift rate expectations.
- ڕاستەقینە yield = nominal yield − inflation; currencies often track ڕاستەقینە yields.
- Inflation → rate expectations → ڕاستەقینە yields → currency direction.
