Housing loan interest

Bank Negara Malaysia's decision to increase the Overnight Policy Rate (OPR) by 25 points on 9th Mar 10 has increased BLR-based housing loan interest. Base Lending Rate (BLR) which is tied to OPR has increased from 5.55% to 5.80%.
For the month of March 10, I paid additional RM50++. I estimate the additional cost would be more than RM50++ next month because first 9 days of March was still using old rate.
From now onwards, I lose additional RM50++ now to bank :(

Even though today is April Fool, but I'm not fooling you la... But don't be fool by others :D
