How Level I tests exchange-rate quotation, FX regimes, cross-rates, and the arbitrage link between spot, forward, and interest rates.
FX questions at Level I look computational, but they are really convention and interpretation questions first. Candidates often know the arithmetic and still lose points because they reverse the quote, confuse nominal with real exchange rates, or misread the forward relationship.
The stronger reader asks:
That usually determines whether the calculation is even set up correctly.
| FX concept | What it means | Common Level I trap |
|---|---|---|
| Nominal exchange rate | Price of one currency in terms of another | Forgetting which currency is being priced |
| Real exchange rate | Nominal rate adjusted for relative price levels | Treating it as if it were just a re-labeled nominal quote |
| Cross-rate | Exchange rate implied by two other currency pairs | Reversing one leg incorrectly |
| Forward premium or discount | Whether the forward rate is above or below the spot quote under the convention used | Saying a currency is at a premium without checking quote direction |
The exam often rewards candidates who slow down long enough to define the quote before calculating.
| Regime | What it implies | Typical Level I focus |
|---|---|---|
| Floating | Currency can adjust more freely to market forces | FX can absorb part of the macro shock |
| Fixed or pegged | Currency is tied more tightly to another anchor | Policy flexibility may be more constrained |
| Managed | Authorities allow movement but still intervene | Candidate must avoid treating the regime as purely fixed or purely free-floating |
Level I often tests direction, not institutional nuance.
If (S_{A/B}) is the price of currency A in units of currency B and (S_{B/C}) is the price of currency B in units of currency C, then the implied cross-rate is:
$$ S_{A/C} = S_{A/B} \times S_{B/C} $$
The intuition matters more than the notation: the intermediate currency cancels only if the quotes are aligned correctly.
A simple covered-interest relationship can be written as:
$$ F_{d/f} = S_{d/f} \times \frac{1+i_d}{1+i_f} $$
where (d) is the domestic currency and (f) is the foreign currency under the quote convention being used.
The point is not to admire the formula. The point is to see that the forward rate must stay consistent with spot exchange and relative interest rates, or arbitrage would exist.
An analyst calculates a cross-rate and gets the numerical reciprocal of every answer choice. A weak response says the choices must be wrong. A stronger response asks whether the quote was inverted by accident and whether the exam wanted domestic currency per foreign currency rather than the reverse.
That is classic Level I FX design: the convention error is often the whole question.
An analyst says a currency must be at a forward premium whenever its home interest rate is higher than the foreign interest rate. What is the strongest critique?
Best answer: That conclusion depends on the quote convention and on which currency is defined as domestic versus foreign in the forward relationship.
Why: Level I often tests whether you understand the logic of the relationship rather than applying the sign mechanically.
