Best indicators for inflation, from Asindu Drileba
November 10, 2025 |
The more goods cost, the more money visa makes since the fees they charge Issuing banks & acquiring banks are based on a percentage basis. So, higher prices (inflation) –> better predicted revenues for Visa? Inspired by a nice documentary on the history of VISA.
I wonder what the best indicator for inflation would be for testing this? CPI? Oil?

I was thinking as to find a similar indicator for economic slow turn, spending cuts. It came to my mind to follow sales slips. I live in Malta which is a very tech friendly country for spending habits such as Apple/Google Pay availabilities, many digital banks access etc. I often asked if I need a receipt that I usually don’t. It depends for every country but if there is a rule for stores/restaurants to keep at least a copy for each transaction then it might be the indicator to follow. It might be used for inflation as well but of course needs detailed information.
Pamela Van Giessen comments:
To the best of my knowledge, merchants are not required to keep receipts. We track each sale but it will be the credit card processor or platform such as Square that holds the credit card or Apple or Google pay receipts. I can’t imagine that merchants would be willing to share their sales data. I know I wouldn’t.
Visa doesn’t care how much goods cost. They get their nearly 3% processing fee (+ .10 or .15 per transaction) whether there are 20 transactions for $100/ea or 40 transactions for $50/ea. In fact, they make more $ on a higher volume of transactions.
I don’t think tracking Visa or MC, etc could be a meaningful prediction of inflation as all the credit card companies continuously fight for market share. Note that they all send out multiple credit card offers to everyone all the time. Then, you have a store like Costco that only accepts their credit card (Citibank).
Additionally, there are people who use primarily cash. Those $ would be left out. You may say that cash use is low, and maybe it is. What I can tell you is that today at a market 80% of my sales were cash and that was likely the case for all the other merchants at this market. Older people especially use cash a lot. Just like drug dealers.
I have a theory that the cash economy is much bigger than everyone thinks. Insight into that might be more interesting.
Carder Dimitroff responds:
After considering Panela's cash sales point, I remembered that several companies required customers to switch from credit card payments to bank transfers. Additionally, several small establishments offer incentives for customers to pay in cash. They may be attempting to simplify their accounting and tax reporting. I do know that the federal government has immediate access to individual credit card transactions.
Pamela Van Giessen adds:
I thought it was the Fed that used to report on aggregated credit card data.
The other challenge with using credit card financials is that the credit card processors raise their % cut all the time. This is not due to actual inflation; it is due to them having a government protected moat that allows them to take more and more whenever they want because merchants are stuck with the whole system and consumers don’t realize that they will pay for the service — in increased prices. Every time Square, PayPal, etc., send me notices that they will be increasing fees, I increase my prices. I guess that is a kind of proxy for inflation but it’s a lousy sort of financial market induced inflation not based on anything more than their desire for more profits. I am all about free markets but the credit card processing biz is not even close to a free market.
The government using credit card processing to surveil us may be one reason I see more and more people using cash.
Larry Williams suggests:
Stock market is good predictor of inflation.
