The primary challenge the institution faces when managing both the loan and the interest rate swap, especially when transacted with the same bank, is the difference in accounting treatment and collateralization practices. While the loan typically falls under the 'banking book' and the interest rate swap under the 'trading book,' these differences impact how the transactions are treated in terms of accounting and collateral requirements. This discrepancy can lead to challenges in managing the financial statements and ensuring that the hedging strategy effectively mitigates the intended risks.

A is incorrect. Institutions can definitely transact both loans and swaps with the same bank. The challenge arises from the differences in treatment of these transactions, not from the inability to transact with the same bank.

C is incorrect. Assuming the swap is correctly structured, it should effectively hedge the interest rate risk of the loan for a fixed rate.

D is incorrect because the capital treatment for the loan (banking book) and the swap (trading book) is not identical, which is the root of the challenge, not a source of inefficiency.

Things to Remember

• The 'banking book' consists of assets and liabilities that the institution holds with the intention to hold to maturity. Transactions in the banking book are usually accounted for at their historical cost or amortized cost.
