14:17 <@MagicalTux> when we were in the second largest bank in Japan, we represented more than half of all the volume of SWIFT processed by that bank (almost overloading their systems a couple of times)
I can see:
1. No mention of overloading computer systems.
2. No mention of a million SWIFT transfers every day.
Japan is economically very different from the rest of Asia.
Well it does not exactly say the word computer, but since they are also in the same quote basically claiming they sent about a million SWIFT transfers every day it pretty much confirms the obvious which is that it is computer systems and not manual systems this quote is talking about as the bank is not going to handle million transfers manually.
A million SWIFT transfers is some number you pulled out of your hat. You imply the bank has several million large companies as customers. This is not realistic.
A SWIFT transfer isn't much manual work. Returns and rejects are.
Since they claim they represented more than half of the volume it means something in the range of million since the volumes at the bank are several millions.
Source?
I claim that my calculations make about sense and you are just refusing the interpret the quotes the obvious way without any kind of justification for that, just that you refuse to believe the obvious.
Here is another quote from IRC, which you conveniently ignored:
14:10 < sturles> MagicalTux: Why only 10 SWIFT transfers per day? Is that commonplace for customers in your bank?
14:12 <@MagicalTux> sturles, most companies in Japan will do one, maybe two SWIFT transfers a month to providers overseas (actually most will do zero)
Do you really think the bank has more than 30 million companies paying via SWIFT (most companies will do none) as customers? Assuming 2 million SWIFT transfers a day where MtGox has half. Let me ask again: Can you provide a source for that number? In most cases a simple payment by credit card or another method will do fine, and there is no need for a SWIFT transfer. Not daily. Not every week. Not even every month for most companies.
And Japan is different from the rest of asia but in the direction that Japan has bigger percentage of banking functions than many other parts so the number of SWIFT messages processed are probably higher in Japan than my calculations show.
Or it could be that Japan, as a highly advanced and organized society, has more practical payment options available to them. E.g. international credit cards with low fees.
