Thanks. xe.com was the other site i couldn't remember earlier.
I have GBP, EUR, JPY, TRY data and should have something to post soon. I've already looked up the necessary dates, so don't want to make others repeat my work (until they want to verify and further analyze what I've done) :)

I don't believe there is any single official rate. Oanda, XE and WSJ are all good guides, but I don't think any of those show you the full range of rates on a given day. Since many currencies can have a trading range of well over 1% on a single volatile day, an average rate doesn't necessarily tell you if the rate you received was particularly good or bad. A Bloomberg terminal is probably the best source of data, since you can pull up a full chart of trading rates for any two currencies on any given day to make sure your transactions fall in the range. But most of us don't have one of those.

Also note that if you're looking at ATM transactions, you should be looking at the rates for the day of the withdrawal. If you're looking at credit card transactions, you should be looking at the rates for the transaction "posting date" listed on your statement and not the "sale" or "transaction" date.

Notes:
It took me over 10 minutes on the phone with Capital One to get a travel auth posted prior to making this test. I never call ahead for any of my other 0% forex cards for any of my travels. This is one reason why I seldom use the Cap One card.

I conducted a similar test a bit more than a year ago (see my post in this same thread from April 2009) and the card with the best exchange rate then, as it is now, was the Citibank Chairman Amex. Although it has a $500 annual fee, I have nothing but wonderful things to say about the service on this card. It is truly exceptional.

I was surprised that the Pentagon Federal Amex came through with the worst exchange rate. It was also surprising to me that all four of the Visa cards posted the exact same exchange rate. I wish that I had had a 0% MC to test (but the only one I know about is from Capital One and I don't want any more of their cards). Rumor has it that MC offers the best foreign exchange rate (compared with Visa and Amex).

Considering how tightly the cards' rates fall between the Min and Max Market Exchange Rates for the posting date of the charges, I think that it's safe to say that all of the cards I tested are truly 0% forex cards. This is in response to the insistent but unproven assumption that one member makes in this thread that all 0% forex cards include a hidden 1% surcharge from the card issuer (i.e. Visa, MC). I believe his/her information to be incorrect. With the possible exception of the Pentagon Federal Premium Travel Rewards Amex, all of the results from both of my tests (the one from April of 2009 and this most recent one) are consistent with the conclusion that these cards' claims that they are 0% forex cards are entirely accurate.

What do they give you for that $500 annual fee?

Besides low forex transactions?

Of course a lot of businesses overseas won't take Amex.

I always call before I travel to put notices on the credit and debit cards I will be using overseas. However, on my last overseas trip I somehow completely forgot to do this. I remembered when I pulled out my Capital One to pay for something. I was worried they would reject the transaction, but it went through as did all my other transactions during the one week trip.

Crap one FTW! never called ahead for my last trip to the Philippines and South Korea, and 1 rewards point per dollar spent.

Speaking of Capital One, it seems they are offering 2 new online only checking accounts. Online Interesting Checking and Rewards Online checking, so I guess you don't have to be located in a state where they have branches to get a checking account with no foreign transaction fees.

Thanks for a very informative, fact-based survey and post. It's rare that we see such a thorough, real world test of forex fees (or anything else) on FT.

thanks for recognizing my effort.
it's nice to know that it's appreciated.

It absolutely is appreciated. We also appreciate the patience of the Woolworth's clerk who let you ring up six identical transactions in a row! :)

It would of course be even better if we can continue to get tests like this spread over time so we can see whether the Chairman Amex is just happening to get a better rate on a particular day or if it consistently does better than the Visa cards.

FWIW, in my friend's recent tests, his Citigold ATM card has consistently gotten slightly better rates (<1% better) in several trials against his TD Bank and Schwab ATM cards in identical, serial transaction tests like this in several countries. So I wonder if Citi processes its own forex transactions and is therefore able to provide better rates, as opposed to some of the smaller banks and CUs that seem to use Visa/MC to do the forex transactions for them. Or it could just be luck of the draw on a given day.

+1

Yea, that kind of effort should be appreciated.

Pentagon Federal Credit Union
 

Would it be worth a call to Pentagon Federal Credit Union to get them to EXPLAIN why the difference for THEIR two charges? They may understand why their own cards are different.

+1
Very detailed report.
Thanks for all the hard work in getting that done.

I sort of tested this a couple of years ago (used my AMEX Blue and CapOne) and the CapOne FOREX rate was always worse than AMEX, and in a couple of cases was worse than AMEX FOREX+fees.

The Citi ATM is where I got screwed. OK FOREX rates, but fees up the wazoo.
