| there are several factors to consider.
as a laymen, u'd have difficulties actually interpreting the trend of any foreign currency movement.
let's say you do a CHF mortage at 3.5% with the GBP to CHF rate at 2.5CHF to the Pound.
when CHF rise to 2.4CHF to the pound, maybe within the year, would you panic and swap it back into pound ? once you do that you'd incur at least a 10 or 20bps charge on the basis swap (of cos again it depends on how the bank package it for u, they might absorb it). then next you see it swinging back to 2.5CHF to the pound again.
mathematically it might make sense but you'd have to have a strong believe in how the currency will move and you have to stick to your strong believe for the long term switch to work. else you would be listening and believing every other comment of the economists and incurring additional cost only to be made to look stupid after a few switches. |
