Saudi families paid for the school year in one week, and they paid for it out of the rest of the household budget. The Saudi Central Bank’s point-of-sale bulletin for the week ended August 22 records SR1.04 billion ($277 million) of education spending, up 133.9 percent on the week before. Total card spending barely moved: SR14.17 billion ($3.78 billion), down 0.1 percent. The money that went to tuition desks and school suppliers came from somewhere, and the bulletin says where. Restaurants and cafes fell 8.6 percent to SR1.67 billion. Food and beverage sales fell 4.1 percent to SR2.11 billion.

The confirmed numbers, from the central bank’s weekly bulletin. Education card payments reached SR1.04 billion on transaction counts up 55.7 percent. Books and stationery, the small sector that tracks the same calendar, rose 30.2 percent to SR155.18 million. Clothing added 1.7 percent to SR1.26 billion. Across the whole economy, the number of card transactions fell 4.9 percent to 237.35 million even as the value held steady. Riyadh took SR5.13 billion of the week, up 6 percent, while Jeddah slipped 4.4 percent to SR1.8 billion and Dammam and Alkhobar rose 9.3 and 11.5 percent.

Two of those numbers carry most of the meaning. The first is the flat total. A 134 percent surge in one sector inside an unchanged overall figure points to reallocation rather than new demand. In the short run the household card budget behaves like a fixed envelope, and the school bill was settled by eating out less for a week. That is the ordinary arithmetic of a seasonal expense, stated plainly because weekly surges are often read as momentum. This one is a transfer.

The second is the divergence between value and volume. Fewer transactions, same value, means larger payments. Tuition is the classic large-ticket card payment, a single swipe that carries a term’s fees, and its weight in the week explains why the count could fall 4.9 percent while the value held. The bulletin, in other words, caught the settlement week: the point at which obligations that families had planned for all summer became payments.

The sequence matters too. The prior bulletin, for the week ended August 15, showed education up 62.7 percent to SR446 million. This one shows a doubling on top of that. Two accelerating weeks running into the first bell on August 23 map the private-school fee calendar with some precision: deposits and supplies first, then the main instalment in the final week. Talat Hafiz, the economist, called the surge the normal seasonal effect of the back-to-school period, and the series supports him. Last year produced the same shape at the same point in the calendar.

The geography is the more durable signal. Riyadh’s 6 percent rise against declines in Jeddah and Abha is partly the same concentration that runs through most Saudi economic data this year, from contract awards to industrial licensing. But education spending clusters where private schooling clusters, and the capital’s share of this particular week is a reminder that the school economy, like much else, is increasingly a Riyadh economy. Dammam and Alkhobar, both up strongly, suggest the Eastern Province corridor is the second pole.

What to watch is the other side of the mountain. The week now being counted, the first with children in classrooms, should show education falling back toward its normal SR400 to 500 million range and restaurants recovering their share. If the total holds near SR14 billion through that rotation, household spending enters September intact after absorbing the year’s largest scheduled expense. The central bank’s August monthlies, and the education line in the next inflation release, will show whether fee levels themselves are rising faster than the wider basket. That number, not one settlement week, is the one that says how the cost of schooling is moving.
