Optimization of a multi-currency portfolio of foreign assets
locate the portfolio on the efficient frontier of the trade-off between risk and expected return defined in terms of the investor’s domestic currency.
two-step process of handle asset allocation with currency risk
(1) portfolio optimization over fully hedged returns
(2) selection of active currency exposure
choice of currency exposure (to decide % hedge of the currrency exposure
(1) Diversification consideration
+ If hold long term -> no need to hedge currency exposure
+ If negative correlation -> no need to hedge
+ If asset is FI -> should hedge
(2) Cost consideration
+ Hedging cost (trading cost, oppotunity cost)
+ Hedge large movement can material affect
Currency management strategies
+) Passive hedging -> totally hedge
+) Discretionary hedging : allow for partially currency exposure
+) Active currency management: seek currency risk with profit in mandated risk limit
+) Currency overlay:
*) Internal manager: hedge- External manager: seek alpha
*) Correlation between 2 parts should be low
should hedge toward fully in:
+ short term investment
+ portfolio owner is risk averse and regret aversion
+ portfolio has liquidity & income need
+ portfolio has FI
+ hedging cheap
+ financial market volatility
+ The beneficial owners/management oversight committee are skeptical of the expected benefits of active currency management.
tactical decision of currency risk exposure invesment
+ Econ. fundamental
+ technical analysis
+ carry trade
+ volatility trading
limitation of economic fundatmental of active currency management
+ modeling factor effect fx is dificult
+ modeling equilibrium rate is difficult
limitation of technical analysis of active currency management
+ lack formal econ.model
+ subjective judment
+ less useful in trendless market
tool of currency hedge related to forward contract
+ stratic hedge (hedge 1 times initial) -> unwanted currency exposure
+ dynamic hedge:
*) if foreign increse -> should increase hedge size
*) if spot rate increase -> should increase hedge size
+ FX swaps:
+ Roll yield
*) For a long position: Roll yield= (𝑆𝑃/𝐵−𝐹𝑃/𝐵)/𝑆𝑃/𝐵
*) For a short position: Roll yield=(𝐹𝑃/𝐵−𝑆𝑃/𝐵)/𝑆𝑃/𝐵

time decay
Time decay is a measure of the rate of decline in the value of an options contract due to the passage of time
domiestic currency return of Portfolio
P𝑅𝐷𝐶=w1 x (1+ RDC1) + w2 x (1+RDC2) - 1
domestic currency return of asset class
Rdc = (1+ Rfc) x (1+Rfx)- 1
+ Rdc: Domestic currency return of asset class
+ Rfc: Foreign currency return of asset class
+ Rfx: the percentage change of the foreign currency against the domestic
currency
currency overlay program
Definition:
+) Limited: means that the PM has outsourced managing currency exposures to a firm specializing in FX management
+) Broader: hired currency overlay manager to take directional views on future currency movements
Uses:
+) the foreign-currency asset portfolio hedged + add an external currency overlay manager to the portfolio
+) currency overlay program should generate alpha that is UNCORRELATED with both the major asset classes and the other alpha sources in the portfolio
carry trade characteristics:
+ involves borrowing in low-yield currencies and investing in high-yield currencies
+ equivalent to trading the forward rate bias
+ is a leveraged position
+ lower volatility is better for a carry trade position (da hoi trong Topic test)
Non-deliverable forwards (NDFs)
Why: because some emerging country restrict movement currency move in/out of country (CNY. BRL, RUB) to settle contract -> NDFs
Benefit:
+ lower credit risk
+ tail risk (change gov policy)
+) NDF pricing will reflect the individual supply and demand conditions (and risk premia) in the offshore market
risk reversal strategy
