Markets, wherever they are will likely cater for their customers. If the majority are in US/Europe then no reason why an exchange at GMT+10 couldn't operate according to NY/London hours or simply remain open 24 hours. But for fun, here are some ideas for candidates in an EU compatible time zone: Iceland (withdrawing EU application), South Africa, Brazil, UAE, Qatar, Bahrain, Kuwait, Russia, Turkey, Uruguay, Mauritius, Nigeria, Ghana, Kenya. Though, don't think it's worth worrying about. NY's and London's time aren't up yet. Historically, the cost of doing business (trading) has fluctuated. The best times could still be to come, after all the 20s are almost here again.
In the recent circumstances it does not matter as much as you think it does. Which is what Krugman actually wrote.
The OP makes some good points, and I suppose I would be more worried if I lived in the UK, with the threats they face. Here we have some protection. I seriously doubt that Sanders will get the nomination. if Hillary were indicted for example, which is unlikely, the party would immediately push forward an establishment replacement like Joe Biden. Hillary herself is totally bought and paid for by the bankers, etc so she is mainly going to talk, or maybe sock it to the middle class like her husband did. Republicans are still likely to control the House and therefore could block anything like a transactions tax, provided they have some backbone. They are ever quick to sell out their base, but I suspect they would find their courage if the big check writers on Wall Street were threatened.
From the guy whose head is stuck so far up Krugman's ass the man can see it every time he brushes his teeth.
hmm not so sure about the simply stay open 24 hours comment. Im a european equity/bond trader, im not going to trade those markets from hong kong at 3 in the morning. It needs to fit in with the time zone. I know a few guys that have gone to Dubai its pretty geared up for trading there. Great time zone. A lot of the European places opening up there and zero income tax.
