So invest $cap/10 over 10 years and you have a ssb ladder which pays ~3.3% every year?
Or would you invest $cap right at the start and reinvest every 10yrs?
I think the supply will be greatest only in the beginning
after which monthly the new supply will be less and thus limited (a cap in which we can purchase therefore makes sense)
basically those who opt out (get back principal) will allow new investors to take over their positions (done monthly)
and also once the SSB matures, the product will be rolled over to exisiting or new bond holders. new SSB can also be created, which this may be done yearly
so basically MAS is the one that decides how big the SSB pool will be
for example a 10 billion dollar pool, then the bonds will keep rolling over inside this portfolio managed by MAS
they can expand or reduce supply by controlling the size of this SSB pool
Basically MAS can be seen as a portfolio manager, with a huge basket of SGS bonds. buying into the SSB, is like buying a small piece of that basket... if u dun want it, others can take over your piece
