Dear Experts,
My bank wants to issue LC to an X Bank,but with no RMA. Y Bank only has the RMA with Z Bank which is in the same country with X BAnk. My bank has the RMA with Y bank and Y Bank is willing to advice LC thru Z bank first, and Z is requested to advice to X Bank in th end.
We plan to issue the LC first to bank Y, but how do we say in 57D MT700 (Advice Through) ?can we say :
1. SWIFT CODE BANK Z, as the 2nd advising bank
2. SWIFT CODE BANK X, as the beneficiary bank.
so those two banks (bank Z and bank X) will be mentioned in 57D.
Your opinion does matter.

Hi Pal,

IMHO, bank X in field 57A
Bank X is the beneficiary's bank where, probably, the transaction is domicilied.
I think that the intermediary banks will try to contact the beneficiary directly
for marketing purpose.Swift Book no. 7, speaks of Receiver bank.
Other comments appreciated

57A or 57D can only allow one bank according to SWIFT format.
It seems to me that the only way to proceed it is as follows.
Your bank sends a MT-700(indicates 57A or D as X bank) to Y bank asking for routing your MT-700 to Z bank via MT-710.

It would be a lot easier if your bank has RMA with Z.....
