You could check with headhunters (see the FAQ on this site) in banking/IT. Some would argue Singapore's been on the brink of recession for years so it's not surprising that the numbers finally confirm suspicions of such.
Perhaps there are more opportunities here than in Argentina, but tough to say as each situation different.
Consolidation is definitely occurring in the financial services sector, as much here as any other country. IT companies have similarly struggled as they have elsewhere in the world.
However the standard of living here for both Singaporeans and foreigners is quite high compared to many other countries in the world and you may find that money is not the only consideration for a move here.
If it's on your mind or you are looking at the prospect of going to Argentina unemployed then it is definitely worth taking a look. There always seem to be jobs advertised in the paper etc so presumably some people are still looking for good employees.
