Well, that 90% figure may or may not be accurate, depending on which slice of the currency market you are referring to. Would you care to cite your source for that figure?
Here's how the overall market is divided (figures taken from the BIS 2010 Triennial Survey, and rounded):
• $4 trillion per day traded in the worldwide foreign exchange market
(this total includes the spot currency market and all of the various currency derivatives markets)
• $1.5 trillion per day traded in the spot currency (forex) market
(this is 37.5% of the overall currency market)
• $1.365 trillion per day traded in the institutional spot forex market
(this is 91% of total spot forex, and 34.1% of the overall currency market)
• $0.135 trillion per day (= $135 billion per day) traded in the retail spot forex market (our market)
(this is 9% of total spot forex, and 3.38% of the overall currency market)
Which segment of the overall market are you referring to?

I don't think that statement can be supported. For the sake of discussion, let's assume that your 90% figure, above, is correct.
Assuming that ALL non-speculative currency transactions involve real money transfers, then the question becomes what portion (if any) of speculative currency transactions also involve real money transfers.
The largest speculative trades occur between mega-banks at the interbank level of the market, and those trades absolutely are booked as real money transactions.
And, large hedge funds, large private equity funds, and high-net-worth individuals who have direct access to one or more of the banks in the interbank network also do speculative trading, and their speculative trades are booked as real money transactions, as well.
So, at least a portion --- and possibly a very large portion --- of speculative trades do involve real money transactions (what you referred to as "transfer of currency").
Again, would you care to cite your sources?
