OK SAG, please do tell ...
But, you're kidding me, right? I see all this financial commentary here on FR, and fully 95% of it absolute crap. You don't beat the bankers by playing THEIR game (in this case depositing funds in their thoroughly criminal institutions), you beat them by FADING the game that they must play.
Take a simple case: the Euro.
Do you know what EuroBunds are? Or BOBLs? Or Schatzes? No? Well, I'm not surprised. They are, respectively, 10-year, 5-year, and 2-year Euro-denominated bonds. Just like the 10-years and 5-years and 2-years in the US. The Euro bonds are (duh!) denominated in Euros; the 10-years and so forth are denominated in USD. Similarly, the Long Gilt in the UK (10-years). OK, so far?
Now, here's a question for you. If you don't get this one right, forget about trading in the way that I have implied (and will explain), ok?
When a country goes to negative interest rates, and another country does not at the same time, long rates, short rates, doesn't matter, then: HOW SHOULD YOU TRADE their assorted debt-mkt instuments?
I'll make it simpler still: exclude the US from this discussion/question/answer.
I await your answer.
FReegards, and good trading to you!
