Think the bank offered endowment or insurance products in general, cos don’t want clients to use leverage to go into something risky and go bankrupt (potentially even losing the leverage). Once the client sets aside 70k and gets leverage of 180k to put total of 250k into the endowment, upon maturity 20Y later, the policy’s surrender value is ~400k (assume ~4% pa returns). Deduct 20Y of interest, to b conservative, say 2%pa of 180k (or 72k over 20Y) and return 180k loan back to bank, client should pocket up to ~S$140k. This is based on S$70k of original capital.
Banker also suggested I put in 30k into a China high yield fund (apparently 10% pa returns but not guaranteed) and use the dividends to pay off the annual bank interest, any extra dividend goes into the bank account. So just put aside 100k away for 20y and “do nothing”.
