Let's test a theory

$OCBC Bank (O39.SG)$ If interest rate drops, but dividend maintains, wouldn't 80 cents dividend at 12.5 price yield 6.39% be super attractive compared to the low expected yield from T bills or SSB? If net interest income drops a little only due to uptick in new loan disbursement, then wouldn't dividend yield have to drop to say 5.5%, implying an increase in share price because its quite unthinkable for ocbc to cut dividend. Investors with more risk appetite will want to park their money away from low interest yielding assets into blue chip with good dividend returns thus driving up share price. Could this be possible?
