Explanation

In this interest rate swap scenario:

• BNP Paribas is the pay-fixed counterparty (receives floating rate)
• Credit Agricole is the receive-fixed counterparty (pays floating rate)
• The forward spot curve is initially upward-sloping
• LIBOR starts trending down and the forward spot curve flattens

Analysis:

1. When LIBOR trends down:

   • The floating rate payments decrease
   • BNP Paribas (pay-fixed, receive-floating) receives less on the floating leg
   • Credit Agricole (receive-fixed, pay-floating) pays less on the floating leg

2. When the forward spot curve flattens:

   • The expected future floating rates decrease
   • This makes the fixed-rate payments relatively more valuable

3. Credit risk impact:

   • Credit Agricole (receive-fixed) now has a more valuable position because they receive fixed payments that are higher than the declining floating rates
   • If BNP Paribas defaults, Credit Agricole would lose this valuable position
   • Therefore, credit risk increases for Credit Agricole
   • For BNP Paribas, their position becomes less valuable, so credit risk decreases

Correct Answer: B - Increase only for Credit Agricole

The credit risk increases for the counterparty who has the "in-the-money" position, which in this case is Credit Agricole as the receive-fixed counterparty when rates are declining.
