R21 Currency Management Flashcards
R21
IPS currency management policy
The IPS’ currency management policy must address:
• How much currency exposure should be hedged passively
• Degree of latitude for diversion from the above
• How frequently hedges should be rebalanced
• Currency hedge performance benchmark
• Permitted hedging tools (forwards, swaps, options, etc.)
R21
Diversification Considerations
Diversification Considerations:
- Time horizon: FX is mean-reverting in long run, so less hedging is needed
- Correlation between RFC and RFX : tends to be stronger for fixed income than for equity, so fixed income portfolios are more likely to be hedged
R21
Costs of Hedging
- Bid Offer Spread
- Options Premium
- Roll-Over cost of forwards
- Adminstrative infrastructure for trading FX derivatives
- Opportunity Costs
R21
When is a highly hedge policy appropriate
A more currency risk -averse and highly hedged policy will be appropriate, if:
- • There are short -term objectives
- • Client is very risk averse
- • There are immediate income/liquidity needs to be met out of the portfolio
- • More fixed income securities are held in a foreign fixed income currency portfolio
- • A low-cost hedging program is possible
- • Financial markets
- • Client does not believe active currency management will improve portfolio returns or reduce risk

Forwards and Foreign Currency Receipts
When a company is recieving cashflows in a foreign currency they are long the currency. Company sells its products in many countries >>> therefore short currency forward contract
R21
Forwards and Foreign Currency Payment
- When a company has to purchase the foreign currency they are short the currency. Company has to buy resources from foreign company e.g. steel >>> therefore long currency forward contract
R21
Hedging Returns - what is earnt
- Hedging the foreign market return only, expect to earn only the risk foreign free rate.
- Hedge foreign market return and exchange rate earn only the domestic risk free rate
R21
Direct vs Indirect Quote
Direct Quote:
DC/FC
Note DC (Price Currency)/ FC (Base currency)
Indirect Quote:
FC/DC
- Focus on the denominator
R21
DAD acromyn
DAD = Down the Ask and Divide
R21
Rdc, Rfc, Rfx definitions
Rdc = return on the portfolio in domestic currency
R<strong>fc</strong> = return on the foreign asset in foreign (local) currency terms
Rfx = return on foreign currency (% change in value of foreign currency
If you hold an asset in a foriegn currency you want the foreign currency to appreciate. If I have a liability I want the foreign currency to depreciate.
domestic currency = home currency
Foreign currency = local currency
R21
Currency Hedging Methods (4)
- Passive - eliminate currency risk relevent to the benchmark. Match currency exposure to benchmark. difficult because of rebalancing considerations.
- Discretionary - some deviation from benchmark by a small percentage. To reduce currency risk and enjoy modest incremental currency returns
- Active - large deviations from benchmark. Goal to make incremental returns from managing currency exposure. Within risk limits.
- Currency Overlay manager - external 3rd party manages currency by active manager. Can take exposures seperately from assets held in portfolio. Generatign currency alpha.
R21
Currency hedging conclusions
- Currency volatility in long run has generally been lower in long run
- When + correlation between foreign asset and foreign currency it will increase volatity in domestic returns in the portfolio and therefore increase hedging need.
- When - correlation between foreign asset and foreign currency it will decrease volatity in domestic returns in the portfolio and therefore decrease hedging need.
- Correlations vary by time periods. Therefore diversification varies.
- Higher positive correlation between foreign asset and foreign return in fixed income portfolios then equity portfolios. Therefore increased fixed income in portfolio then increased need for hedging.
- Amount of hedging down to managers preference
R21
Hedging costs
- Fully hedging increase costs - reduced returns.
- If options used to hedge expire premium is lost - reduced returns
- If forward contracts need to roll often (if less than hedging period) then could result in gains or loss depending on exchange rate.
- Administrative costs
- 100% hedging has opportunity cost. A 50% strategic hedge is often preferred.

Short term strategies (tactical)
Economic Fundemental approach
- Economic Fundemental approach - in the long term currency values will converge to relative PPP. However relative does not hold over short term, but can indicate which currencies have over/under appreciated in the short term.
- Currencies that are expect to appreciate:
- More undervalued compared to their intrinsic value
- Greatest rate of increase in its intrinsic value
- Are those with higher real interest rates or higher nominal rates. Assumes expected inflation is the same.
- Lower inflation rate compared to other countries
- Lower, decreasing, risk premium
R21
Short term strategies (tactical)
Technical Analysis approach
- Past price date can predict future price movements
- Therefore past price patterns tend to repeat
- It doesnt matter what a currency is really worth just where it will trade
- An overbought market would be expected to do down
- An oversold market would be expected to go up
- Support and resistance levels
R21
Short term strategies (tactical)
Carry Trade
- Markets must be very stable
- It is an unhedged trade
- Must be a violation of uncovered Interest Rate Parity to profit
- Borrow in the lower IR currency and invest in higher IR currency.
- If you expect the foreign currency to depreciate by less than the market expectation based on the forward discount you would enter a carry trade. However if the deprecation is far more than market expectation the losses will be great.
- High IR currency in emerging markets can drop very sharply in time of economic stress.
R21
Short term strategies (tactical)
Carry Trade: detailed steps
Assume US IR = 1% and SR - 5%
- Borrow in low IR currency e.g $1,000,000 @ 1%
- Convert Low IR currency into High IR currency using spot rate e.g. $1,000,000 to SR @ 3.75 / $ = SR3750000
- Invest in High IR currency asset e.g $3,750,000 x (1.05)1 = SR3937500
- At end of period convert HR IR currency back to into low IR at spot rate. e.g. assuming unchanged at SR 3.75 SR3,937,500 / 3.75 = $1,050,000
- Pay off original loan e.g. 1,000,000 x 1.01 = 1,010,000. Therefore profit of $40000 on original investment.

Short term strategies (tactical)
Volatity Trade
- Straddles and Strangles
- Vega
- Long Straddle - ATM buy call and ATM buy put and expecting high volatility.
- Short Straddle - ATM sell call and ATM sell put and expecting low volatility.
- Strangle - buy call and sell put but using OTM call and puts. Lower premiums.
R21
Foward contracts for hedging
- Forward contracts preferred to future for currency hedgin because:
- Can be customised
- Can be created between any currency pairs
- Futures require margins which increase operational complexity
- Greater liquidity - forward market larger.
R21
Dynamic Hedge
- Periodic rebalancing
- Can lead to mismatched FX swap. A forward contract for one month to cover a three month postion will need to be rolled at one month and a second forward contract for two month will need to be entered.
- A dynamic hedge will keep hedge ratio close to target hedge ratio
- Higher transaction costs than static hedge
R21
Roll Yield
- Backwardation - forward price is below spot price. Roll return is positive to long side (speculators), and negative to short side (hedgers)
- Contango - forward price is above spot price. Roll return is positive to the short side (hedgers) but negative to the long side (speculator).
- Speculators expect prices to increase, but dont own asset. Will go long.
- Hedgers expect prices to decrease and own the asset. Will go short.
- Spot price assumed not to change. So forward price moves either up or down in relation to spot price. Would depend on interaction between hedgers and speculators.
- Roll yield can be seen as the profit or loss on a forward or future spot price is unchanged at expiration
- Calculate forward premium / discount:
Fdc/fc - Sdc/fc / Sdc/fc
R21
Option based hedging strategies
- EUR based investor long CHF. (risk of CHF depeciation)
- Over / underhedge forward contracts based on view of investor. If CHF expected to depreciate then overhedge, if CHF expected to appreciate then underhedge.
- Buy ATM put options. Assymetic protection limits downside risk and retains upside potential. Has a higher cost.
- Buy OTM put options - cheaper, but less downside protection
- Collar - buy OTM put, sell OTM call. Reduce costs. Limits upside potential.
- Put spread - buy OTM put, sell a deeper OTM put. Reduces cost. Reduces downside protection.
- Seagull Spread - Put spread + sell call. Reduces costs further. Downside protection same as for put spread, but more limited upside.
R21
Hedging Multiple Currencies
- Cross hedge / proxy hedge - a position in one assets hedges the position in another. If obvious contracts not available to short but if if two currencies are highly correlated then a proxy hedge can be created by using the other currency as a proxy. Indirect hedge.
- Macro hedge - hedge focused on whole portfolio, particularly when individual asset price movements are highly correlated. Views portfolio as a collection of risk exposures. Can use a basket of derivatives, which is less costly than hedging each instrument. Indirect hedge.
- Minimum Variance Hedge Ratio - Indirect. hedge. Uses regression analysis. To minimise tracking error between the value of the hedged asset and the hedging instrument. Not applied to a direct hedge strategy (using a foward contract). Should be re-estimated when new information becomes available.
- Basis Risk - Price movements in the exposure being hedged and the price movements in the cross hedge instrument are not prefectly correlated.
R21
Emerging Market Currencies
- Lower trading volume - larger bid-ask spread
- Liquidity can be lower - higher transaction cost
- Non-normal distributions more frequent
- Higher yields, leads to large foward discounts, markets in backwardation, postive roll return to the long side, but negative to short side. Higher yield - larger inflation rate.
- Contagion - correlations between countries increase, therefore diversification benefits decrease.
- Tail-risk - negative events occur more frequently.
- Government intervention
