Took you long enough. That was 3 weeks ago. Affect means to bring about a change, which would apply to this sentence.
Yeah, sorry about the date, I didn’t notice it when I responded. I was just looking at results from a search on Obama threads.
However, you’re still incorrect. “Effect” is the correct word here.
“Then, in September (September again weird) 2008 a strange one to two hour electronic run on US banks to the tune of $550 billion was effected before authorities were able to put a stop to it.”
In this sentence, “effected” has the meaning listed on Dictionary.com, definition #10, verb: “to produce as an effect; bring about; accomplish; make happen: The new machines finally effected the transition to computerized accounting last spring.”
“Affected” would make no sense in that sentence because it would have to be talking about something else that AFFECTED (somehow altered or changed) the two-hour electronic run on US banks, which was already in effect!
