I can see how this could make sense. (Although, without the context it is a stab in the dark as to the writer's intended meaning.)
Perhaps the writer is trying to say, 'convenience' has replaced 'loyalty' for the buzzword we'll use for promoting our company in advertisements.
Just think of how the commercials have changed in theme over the years...
10 to 20 years ago was about 'loyalty':
10 or 20 years ago, commercials and marketing used to be all about loyalty -- bank to customer and customer to bank. Think of grandpas taking their grandkids to open their first account and saying 'Hi' to all the tellers by name. That type of advertisement used to sell.
Today is about 'convenience':
People get more excited about convenience when looking for everyday solutions and products. So, the banking advertisements focus on the ease of making quick transactions. For example, you might see a customer doing everything through their smartphone without ever seeing a familiar smiling face.
"Convenience is therefore the new loyalty."
