Reserve requirement ratio of the banks

Single Borrower’s Limit (SBL) limits a bank’s loans to a single borrower to 25% of their total loan portfolio. In 2017, the central bank has approved the exclusion of the short-term exposures of banks to clearing and settlement banks arising from payment transactions from SBL.

Notes: Some countries totally ban industrial capital owning a bank since "bank" is the heart of this capitalism. A lot of conglomerates own banks in the Philippines. It's really really good for them even though there is SBL rule. 

Reserve requirement ratio currently stands at 20% of the total deposit and deposit substitute. Banks cannot lend out more than this ratio but BSP is planning to cut the rate as of 2017. 

Notes: This is the magic of banking system since banks can virtually create money using this ratio. If you never heard of this, search "money multiplier" effect. Basically, most of the money in this world, doesn't really exist. It's just a number in the computer system.
