Here are some example:
Proxy hedge:
US (USD local currency) company has exposure in Danish Krone. Since the Danish Krone is pegged to the EUR and it is cheaper to do a hedge in EUR, the company would buy a forward (sell EUR and buy USD) to more or less offset its DKK exposure.
Characteristics of proxy hedge:
- Significant hedging out the exposure since the new currency you choose as a proxy (EUR) has very high correlation with the currency you want to hedge (here DKK) so you are left with (small) basis risk.
Cross hedge:
Same company same DKK exposure, but it chooses now to buy a DKK/British pound forward contract (sell DKK and buy British pound). With this forward, it essentially convert the DKK exposure to a British pound exposure.
It does this because of various reasons:
- It feels more comfortable with BPD exposure than DKK exposure (e.g., more correlation btw USD and BPD, feell BPD is not volatile,…)
- It may have some (unrelating) offsetting CF in British pound (for example it must pay some contractors in British pound) thus providing a natural hedge.
Characteristics of proxy hedge:
- It is not a hedge actually, more a conversion of currency risk from one foreign currency to ANOTHER foreign currency. The risk is still (more or less) there but you manage it through other means.
Hope it is clearer.
