What's the difference between CROSS HEDGE and PROXY HEDGE?

CFA Level III
#1

What’s the difference between CROSS HEDGE and PROXY HEDGE? It’s in reading 29, session 9.

#2

I’d call those the same thing with only a little situational semantic difference (like I think I would say “We can’t do that - it’s a terribly risky cross hedge” or “Well it’s too bad that we don’t have enough liquidity to hedge in the T-bill futures market but the Eurodollar futures market provides a good proxy hedge”). Do your readings suggest any difference?

#3

Proxy hedge: currence hedging Cross hedge: other transactions That’s what I can see.
