Answer:
£30 million
Explanation:
Banks net exposure serves as the the money currently owned by the bank.
Credit to bank;
Loans to corporate customers is bank's money since customers will repay the loan back to the bank even with interest = £120 million
Total credit owned by the bank =
£120 million
Debit;
Deposit owned to customers = £70 million (It is customers money not bank's)
Money sold forward by bank is also going out of banks pocket (debit) =£20 million
Total debt owned by bank = £70 million+£20 million = £90 million
Bank's net exposure = Total credit - debt owned by bank
Banks net exposure = £120 million - £90 million
= £30 million
