The increase is higher than the 7.1% growth Mastercard had forecast in September, when it anticipated consumers would pull purchases to October in the hunt for early deals.
Return Inventories To Normal
Retailers including Amazon.com Inc and Walmart Inc in the United States offered large discounts during the holiday season to get rid of excess stock and bring back inventories to normal levels.
That led to strong demand for everything from toys to electronics during the five-day-long period between Thanksgiving and Cyber Monday.
However, sales of electronics dropped 5.3% over the broader roughly two-month period, according to the Mastercard SpendingPulse report.
But sales in the apparel and restaurants categories, rose 4.4% and 15.1%, respectively, helping boost the overall number.
Online sales jumped 10.6% in the period, slightly less than the 11% increase last year, the Mastercard report said.
Meanwhile, during the cyber week, total retail sales had jumped about 11%, a separate Mastercard SpendingPulse report in late November showed.
Mastercard SpendingPulse measures in-store and online retail sales across all forms of payment. It excludes automotive sales.
