While it is always right to promote prudence, and promote keeping enough cash buffer, and to calculate different interest rate scenarios (as all banks have always been supposed to advise customers in such a way for years), Lion King has gone further by repeating similar messages/videos in various ways, exaggerating 50% haircut, and to quote irrelevant cases like China's recent spike of 30%, which is actually overnight or 7-day repo rate, while Singapore's mortgage loans are based on 1-month or 3-month SIBOR/SOR, which does not usually have such spikes (just check the historical chart).
By doing so would raise suspicion that Lion King is doing this for selfish reasons, e.g. to justify his recent sell, or to buy his next target at lower prices. Well, actually this is what most people are here for, but I'm just quite free now, and would like to point this out. I'm not saying Lion King should not do this, everyone has his own reasons, and forum is an open space for all to find info, discuss, and try to achieve his hidden agenda.
