Is the bonus interest compounded?

No, the bonus interest does not compound. Only the base interest does.

• Your base interest is added to your balance every day, allowing it to compound and grow faster - exactly like how the interest mechanism works with your Main Account and Savings Pocket today. 
• Your bonus interest is calculated daily on that daily ending balance which includes the base interest that is posted to your account daily. The calculated bonus interest will be accrued and accumulative until the end of tenure. Upon maturity of the term, the cumulative bonus interest will be posted as a single lump sum entry to your Bonus Pocket.
