1.Q : So does our cost gets better with the lower LD?
A. : It depends. Cost of deposit on Thai Life deposit is low at 0.5% compared with other deposits.
However, this is still lower than yield from inter-bank placement of 2.44%. Therefore, a drop in LD from Thai Life deposit actually bad for TCRB.
Overall, it is better with higher LD from lower excess liquidity.
The opportunity cost, being the interest gap of 0.98% (yield from interbank 2.44 % - COF 3.42 % (Incl. DPA 0.47%))
2. Q : How much saving we made on the lower cost, roughly ?
A : Exclude Thai life, the opportunity cost saving from lower excess liquidity is about 1 MB per year ( LD 93.3%)
If LD ratio is up to 95% we can save more about 4 Mb. per year
