Covered interest rate parity - formula a
Covered interest rate parity - formula b
Forward premium/discount - formula
Forward premium on the domestic currency
The domestic currency will trade at a forward premium (Ff/d > Sf/d) if, and only if, the foreign risk-free interest rate exceeds the domestic risk-free interest rate (if > id)
Mid-market spot rate
Used for FX transactions
Uncovered interest rate parity expected return
The expected return on an uncovered foreign currency investment should equal the return on a comparable domestic investment
Uncovered interest rate parity condition in terms of the expected change in the exchange rate
Return on a uncovered investment formula
- PPP
- Absolute
- Relative
- Ex ante
- Purchasing power parity
- Reflects national price levels
- Reflects actual inflation levels (observed for 3 to 5 years horizons)
- Reflects expected inflation levels
Relative version of PPP
- The percentage change in the spot exchange rate (%ΔSf/d) will be completely determined by the difference between the foreign and domestic inflation rates (πf – πd)
- %ΔSf/d ≅ πf − πd
The ex ante version of PPP
The ex ante version of PPP focuses on expected changes in the spot exchange rate being entirely driven by expected differences in national inflation rates
%ΔSef/d = πef − πed
International Fisher effect
- The nominal interest rate (i ) in a given country is composed of two parts: (1) the real interest rate in that particular country (r) and (2) the expected inflation rate (πε) in that country
- The f/d yield will be solely determined by f/d expected inflation differential
- if − id = πεf − πεd
The international Fisher effect must satisfy this relation
Real exchange rate - formula
Real exchange rate with explicit risk premium formula
- ( q overline)f/d = long-run equilibrium value
- r = real exchange rate
- phi = risk premium
Real interest rate parity condition
Real interest rates will converge to the same level across different markets
Long-term exchange rate convergence
Gravitate toward their PPP equilibirum value
If uncovered interest rate parity holds, then the nominal interest rate spread (if – id) equals the expected change in the exchange rate ( %ΔSef/d). Similarly, if ex ante PPP holds, the difference in expected inflation rates ( πεf−πεd) also equals the expected change in the exchange rate. Assuming that both uncovered interest rate parity and ex ante PPP hold leads to
- Covered interest rate parity (forward exchange rates are a function of)
- Uncovered interest rate parity (the expected future spot rate is a function of)
- Forward exchange rates are a function of current spot rates. Abitrage locks the foward price
- The expected future spot rate is a function of the current spot rate and the interest rates of each currency
Under low capital mobility
- Uniformly restrictive fiscal / monetary policy
- Uniformly expansionary fiscal / monetary policy
- Bullish - tends to lead to an improvement in the trade balance
- Bearish - tends to lead to a deterioration of the trade balance
Under high capital mobility
- Restrictive fiscal policy / expansionary monetary policy
- Expansionary fiscal policy / restrictive monetary policy
- Bearish - capital will flow out
- Bullish - capital will flow in
The Dornbusch Overshooting Model
A modified monetary model of the exchange rate that assumes output prices exhibit limited flexibility in the short run but are fully flexible in the long run
Mundell - Fleming theory
- The Mundell–Fleming model portrays the short-run relationship between an economy’s nominal exchange rate, interest rate, and output (in contrast to the closed-economy IS-LM model, which focuses only on the relationship between the interest rate and output)
- The model focuses only on aggregate demand. Thus, the implicit assumption is that there is sufficient slack in the economy to allow changes in output without significant price level or inflation rate adjustments
Monetary–Fiscal Policy Mix and the Determination of Exchange Rates under Conditions of Low Capital Mobility
Monetary–Fiscal Policy Mix and the Determination of Exchange Rates under Conditions of High Capital Mobility
Quantity theory
Money supply changes are the primary determinant of price level changes
Taylor’s rule - formula
Taylor’s rule - notation
- i = the Taylor rule prescribed central bank policy rate
- rn = the neutral real policy rate
- π = the current inflation rate
- π* = the central bank’s target inflation rate
- y = the log of the current level of output
- y* = the log of the economy’s potential/sustainable level of output
Taylor’s rule - response coefficients
- Alpha (α) and beta (β)
- As long as alpha and beta are both positive—Taylor proposed that alpha and beta each equal 0.5—the Taylor rule prescribes that the policy rate should rise in real terms relative to its neutral setting in response to positive inflation and output gaps (and fall in response to negative inflation and output gaps)
