1. Bank Bumi Bhd (BBB) has total assets of RM 300 million and a positive duration gap of 8 years. The weighted duration of its assets is 8.8 years while that of its liabilities is 0.8 years. Assuming there is a credible counterparty willing to enter into an IRS with Bank Bumi Bhd for RM 100 million notional and exible tenor (maturity), design an IRS by which BBB can reduce its positive duration gap. Assuming the duration of liabilities is unchanged, what is the new overall duration gap?
