Consider a bank that invests an amount y in risky assets (loans) at t=0. At t=2, each unit invested in the risky asset will yield R>1 and so investment y will return yR. Bank's assets are funded with short-term debts, long-term debt / and equity e so that: y =s +1/+e. The gross interest rate that short-term creditors receive from t=0 to t=1 is 1, the gross interest rate they receive from t=1 to t=2 is rs > 1, and the long-term creditors receiver, at t=2. A fraction a of short-term creditors do not rollover their debt at t=1 (i.e. as withdraw), where a has (approximation) a Normal distribution N(u,0). The bank can repay such creditors by liquidating the risky asset. When one unit of the risky asset is liquidated at t=1, it yields TR. Suppose y=100, e = 10,s=70, l=20, r₁ = 1.2, r₁ = 1.1, p=0.6, t=0.5 and a = 0.1. Table 1: Bank's balance sheet Assets y=100 Liabilities Short-term debts-70 Long-term debt l=20 Equity e=10 a) For what values of R is the bank fundamentally insolvent? For what values of R is the bank fundamentally solvent? b) Suppose R =1.5 (so an investment of 100 would return 150 at t=2). What is the probability that the bank will be solvent at t=2? c) Suppose that at t=1, we learn that R=1.2 and a=0.9. The central bank decides to introduce an asset purchase program. What is the minimum price the central bank needs to buy the risky asset at to prevent the bank from failing? How much cash does the central need to conduct the asset purchase program at that price?

2 2 a To determine the solvency of the bank we need to compare its assets with its liabilities The bank will be fundamentally insolvent if the value of its assets is less than the value of its liabili... View the full answer
