This was a week of macro fear: Trump's threats against Iran, oil that jumped, new tariffs, and bond yields that spiked to an eighteen-month high. We wrote separately about all of these. And then, amid all the noise, one report arrived that is especially worth listening to - because it is a direct window into the question above all others: how is the American consumer doing? American Express (NYSE: AXP) reported, and its answer is unequivocal: the affluent consumer is strong, and keeps spending.
About the Company: Not Just a Credit Card
American Express is not just another card issuer. Its model is unique: it operates a closed loop - it issues the card, operates the payment network, and holds the direct relationship with the merchant. The meaning: Amex sees both sides of the transaction - how much the consumer spends and where - and that gives it both a dual revenue source (merchant fees + interest and membership fees) and an economic-intelligence window into the spending habits of the market's affluent segment.
And precisely for that reason, its report is not just a company report - it is a macro indicator. When Amex reports on card-member spending, it is effectively reporting on the health of the consumer that matters most to the economy: the one who spends.
What Was Reported: Strength Across the Board
Earnings beat. EPS of $4.53, up 11% versus $4.08 a year ago, and above the estimate (~$4.40). Net income rose 8% to $3.11 billion, and revenue (net of interest expense) rose 10% to $19.6 billion.
And here is the heart - the spending. Card-member spending (billed business) rose 9% to $455.8 billion - and according to the CEO, this is the fastest growth pace in spending in three years (currency-adjusted). In other words: not only is the affluent consumer not cutting back, they are accelerating.
Credit quality - excellent. And here is the point that refutes the "consumer under pressure" fear: the net write-off rate stood at 2.0% - stable versus a year ago, among the best levels in the industry. Loss provisions actually fell to $1.1 billion (versus $1.4 billion a year ago), following a reserve release. A credit company releasing reserves rather than building them - that is a sign of confidence, not worry.
A generational growth engine. Amex continues to recruit especially Millennials and Gen-Z, whom it defines as having "higher lifetime value" - young customers who will stay for decades. This is an investment in the future of the customer base.
Guidance rose. On the basis of the strong first-half performance, Amex raised its revenue-growth guidance to 10% and reaffirmed the annual EPS guidance. CEO Stephen Squeri summed up: "an excellent quarter... we are competing from a position of strength." Total expenses, it should be noted, rose 12% - mainly due to investment in benefits and the loyalty program, which feeds the acquisition engine.
Our Connection: The Consumer Who Refutes the Fear
This is exactly the angle that makes the report interesting beyond the stock. In today's macro piece we argued that the market "has seen this movie before" and that behind the noise, businesses are in good shape. Amex is living proof of the second part: while headlines talk about war and tariffs, the affluent consumer is spending at the fastest pace in three years, and paying their debts as usual. The American consumer carries a weight of about 70% of GDP - and when its strong segment accelerates, that is a macro data point that offsets a large part of the fear.
The Bull Thesis
Whoever reads it positively will see a humming machine: spending at a three-year peak, credit quality among the best in the industry, generational recruitment (Millennials and Gen-Z) that builds the future, and raised guidance. The closed-loop model gives Amex a built-in advantage and a dual revenue source, and the affluent segment it serves is more resilient to slowdowns than the average consumer. Bottom line: this is the company that wins when the consumer is strong.
The Bear Thesis
Whoever reads it critically will note that Amex's expenses rose 12% - faster than revenue - because you have to "pay" in benefits to keep customers in the card war. The reliance on the affluent consumer is a double-edged sword: if unemployment rises or the economy enters a recession, that segment too will cut back, and today's excellent credit quality can flip quickly. A reserve release increases profit today but shrinks the cushion for tomorrow, and the stock's valuation already prices in continued growth.
The debate in one line
The bulls see the affluent consumer accelerating: spending at a three-year peak, excellent credit, generational recruitment and raised guidance. The bears see expenses running faster than revenue, dependence on a recession-sensitive consumer, and a reserve release that flatters the present. Both sides are reading the same report.
Summary
American Express delivered not just a strong report, but a macroeconomic statement: the affluent American consumer - the single most important engine of the economy - is strong, spending at the fastest pace in three years, and paying their debts. In a week when the headlines screamed risk, this report is a reminder that the economic fundamentals are holding. The question for the investor is not whether Amex is a good company - the report confirms it is - but how much of the strength is already priced in, and what will happen to the affluent consumer on the day the economy slows. Until then, Amex enjoys the strongest segment in the market, and gives all of us a rare window into what is happening in America's wallet.
