Straight from the horse’s mouth, via Chanticleer:
…up in Hong Kong, as least one of the Big Four was making it very clear that full pass-through was unlikely; the bank was keen that investors particularly understood that deposit rates at zero gave it very little room to move.
If we assume that somewhere between 10 basis points and 15 basis points would be passed through from an initial RBA rate cut, then perhaps the even bigger question is what might be passed on from a second rate cut?
