cpf还房贷，利率升高，需要去cpf网站修改吗？

我记得刚开始的时候，我在cpf网站弄了保险，然后在cpf网站注册了用cpf还款。cpf网站注册每个月还款的时候，会让你填上总共贷了多少，每个月要还多少。如实填了，每个月还多少钱我填的正好就是银行每个月要得钱。目前没问题每个月扣钱也正好。

然后贷款第二年，利率升高，

We write to inform you that, following a revision of interest rate, the interest rate of the above account has been adjusted from 1.15%pa to 1.65% pa on a monthly rest basis with effect from 29th November 2013.

Accordingly, your revised loan installment is SGD****378.00 per month. Please note that this amount is next due on 15th January 2014.

With your acceptance of the letter of Authorization that was sent to you earlier, please be informed that the CPF Board will be apportioning your CPF savings towards the repayment of your monthly loan installments as follows:

- Where there is a decrease in the monthly installments, the CPF board would maintain the CPF portion such that the cash portion paid by you is reduced.

- Where there is an increase in the monthly installments, the CPF board would increase your CPF portion towards the repayment of the monthly installments such that the cash portion paid by you remains unchanged.

目前我的情况是所有的全部是cpf还的，没用过cash。我不是很清楚当时在cpf网站注册时，写的贷款总额和每月还款额是什么东西，需要修改吗？不修改会自动升到最新的还款数额吗？

谢谢。
