Final answer:
The profit is potentially lower owing to various risk factors and interest rate fluctuations. Hedging costs include fees or spreads which are essential for risk management in international financing. Shifting to a fixed payment alters the mini-portfolio's convexity and risk sensitivity while integrating cryptocurrency into banking may influence capital markets and internal bank operations.
Step-by-step explanation:
The profit reported by the credit risk department is likely lower than expected due to several factors, including the perceived riskiness of the loan, the discrepancy between the fixed loan interest rate and potentially higher current market interest rates, and the potential situation where the bank pays more interest to depositors than received from borrowers due to rising rates. When it comes to hedging, the transaction costs include fees or spreads which banks or brokers charge to provide the service of ensuring a specific exchange rate or interest rate. These hedging contracts protect against fluctuations in rates that can affect the profitability of international trade financing or loan agreements.
Changing the refinancing from a variable to a fixed payment impacts the convexity and risk sensitivity of the mini-portfolio, altering its interest rate risk profile. The forward rate for years 3-6, if only the first 3 years are fixed, would depend on market expectations of future interest rates, which can be inferred from the current yield curve.
