Net exposure = (FX

assets - FX liabilities) + (FX bought - FX sold)
Net long position in currency = FI bought more currency than it has sold or have more FX assets than liabilities.
Net short position in currency = FI has sold more foreign currency that it has purchased or have more FX liabilities than assets.

8% and invested proceeds in one-year US dollar loan

(50%) at 9% and one-year sterling loan (50%) at 15%. Spot exchange rate is 1.6$/£

$100mill/1.6 = £62.5 mill
Invest £62.5 mill in loans at 15%
The revenue by the end of the year = £62.5 mill x 1.15% = £71.875 mill
Suppose that the spot exchange rate has fallen in value from $1.6/£ to $1.45/£ next year, hence
£71.875 mill x $1.45/£ = $104.22 mill.
Return on the investments is 4.22%

duration matching and currency matching.
Off-balance-sheet hedge involves forwards, futures, options or swaps.
No balance sheet rebalancing;
No immediate cash flow only future contingent cash flow;
Lower costs and administration.
BUT, we have a default risk of counterparty.

foreign asset-liability book: $100 mill UK loans are financed

by UK CDs at 11%, 100 mill US loans are financed by US CDs at 8%. Spot rate is 1.6$/£.
£ Depreciation to $1.45/£

£ Cost of liabilities: $100mill/1.6 = £62.5 mill
£62.5 mill x 1.11 = £69.375
The repayment in Dollars: £69.375 x $1.45/£ = $100.59 mill
Cost of funds = 0.59%
Net return = (0.5 x 0.09 + 0.5 x 0.0422) – (0.5 x 0.08 + 0.5 x
0.0059) = 6.61% - 4.295% = 2.315%

British loan is equal to 22.188%

£ Cost of liabilities:

$100mill/1.6 = £62.5 mill
£62.5 mill x 1.11 = £69.375
The repayment in Dollars: £69.375 x $1.70/£ = $117.94 mill
Cost of funds = 17.94%
Net return = (0.5 x 0.09 +0.5 x 0. 22188) – (0.5 x 0.08 + 0.5 x 0.1794) = 15.59% - 12.969% = 2.625%

By directly matching its foreign asset and liability book, FI lock in an positive return or profit spread whichever direction the exchange rates change over investment period.

On balance sheet hedging

£62.5 mill Invested £62.5 mill in loans at 15%

FI sells the expected principal and interest on a loan forward at the current forward rate $155/£
The forward buyer of £ promises to pay £62.5 mill x 1.15% = £71.875 mill x $155/£ = $111.406 mill in one year
FI has a guaranteed return on a British loan =
(111.46 – 100)/100 = 11.406%
The overall expected return on the FI’s asset portfolio =

position in FX futures contracts if:
you are planning

to sell Foreign currency in the future;
You want to hedge the portfolio of foreign stocks against the foreign exchange risk;
You are planning to borrow a syndicated loan from a foreign bank;
You are planning to buy foreign bonds in 2 months.
Liabilities in foreign currency exceed the assets in foreign currency.

institute a long-term one-year hedge usually due to defined

maturity (4 times per year). So we need to rollover the futures positions into new futures contracts.
EXAMPLE: Suppose that FI made a £100 mill loan at 15% and wished to hedge fully the risk of £ depreciation. The spot exchange rate is $1.47/£ and forward exchange rate is $1.46/£
The size of each £ futures contract is £62500, therefore, the number of contracts needed:
Nf = £115 mill / £62500 = 1840 contracts to be sold.

year the £ depreciates against the $ from $1.47/£

to $1.42/£ at the spot market and from $1.46/£ to $1.41/£ at the forward market.
Loss on the £ loan:
£115 mill x ($1.47/£ - $1.42/£) = $5.75mill
Gain on futures contracts:
1840 x £62500 x ($1.46/£ - $1.41/£) = $5.75 mill
In this example we ignore the marking to market effect and the basis risk:
If spot and futures prices are not perfectly correlated, then basis risk remains.
Tailing the hedge
Interest income effects of marking to market allows hedger to reduce number of futures contracts that must be sold to hedge

= - 5 c and ΔF = -3 c
Loss

on the £ loan:
£115 mill x ($1.47/£ - $1.42/£) = $5.75mill
Gain on futures contracts:
1840 x £62500 x ($1.46/£ - $1.43/£) = $3.45 mill
Net Loss = 5.75 - 3.45 = 2.3 mill

In order to adjust for basis risk we apply the hedge ratio: h = ΔS t/Δft
Nf = (Long asset position × h)/(size of one contract).

(£115mill x 1.66) / £62500 = 3054.4 contracts
Gain

on futures position:
3054 x £62500 x ($1.46/£ - $1.43/£) = $5.73 mill
Net loss = 0.02 mill

of ΔSt relative to ΔFt.
The h may be estimated

using ordinary least squares regression:
ΔSt = α + βΔft + ut
The hedge ratio, h, will be equal to the coefficient β. The R2 from the regression reveals the effectiveness of the hedge.
R2 = p2 = [Cov(ΔSt, ΔFt)]/ [δΔStδ ΔFt]

The principal should be specified for each of two currencies;
The principal is usually exchanged at the beginning and at the end of the life of the swap (note, in an interest rate swap the principal is not exchanged)
