Uncovered Interest Parity
Uncovered Interest Parity — Hypothesis that high-yield currencies depreciate as carry accrues.
Definition
Uncovered Interest Parity refers to hypothesis that high-yield currencies depreciate as carry accrues. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
FX clears cross-border funding and relative growth; dislocations show up here early. When hypothesis that high-yield currencies depreciate as carry accrues shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what uncovered interest parity is saying. If hypothesis that high-yield currencies depreciate as carry accrues moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Check basis, intervention risk, and rate differentials — spot alone is incomplete. Prefer a short written null hypothesis for Uncovered Interest Parity: what would falsify the current reading in the next window?
