FRED has added 6 data series for the Visa Spending Momentum Index (SMI).
The SMI is a monthly measure of changes in consumer credit and debit card spending. Reported by Visa, the index is calculated from a sample of current depersonalized transaction data collected from its own payments network. An SMI value of 100 indicates consumer spending is increasing at a pace similar to its long-term trend. SMI values above 100 indicate faster consumer spending and values below 100 indicate slower consumer spending. More details are available here.
