Answer:
6.50 years
Explanation:
Data provided in the question:
Amount invested in consumer loans = $75 million
Duration of consumer loan = 3 year
Amount invested in T-Bonds = $39 million
Duration of T-Bonds = 16 year
Amount invested in T-Bills = $39 million
Duration of T-Bills = 6 months
Now,
The duration of the bank's asset portfolio in years
= [tex][\frac{75}{75+39+19.5}\times3] + [\frac{39}{75+39+19.5}\times 16] + [\frac{39}{75+39+19.5}\times 0.5][/tex]
= 6.50
Hence,
The answer is option 6.50 years
