Central Banks Brace for Impact as Inflation Data Floods Markets

This week the global economy serves up a master class in collective second-guessing. Between central bank decisions, employment reports, and inflation data arriving from three continents, markets will have enough signal—and noise—to keep them arguing through September.

Start with the employment picture. U.S. nonfarm payrolls arrive Friday, the number that determines whether the Federal Reserve has political cover for a September rate increase. ADP private payrolls, arriving Wednesday, forecast a tepid 47,000 jobs added, which will either prime the markets for disappointment or set expectations low enough that Friday's number looks respectable by comparison. This is how economic forecasting works now: we study the appetizer to guess whether the main course will be overcooked.

The Fed itself speaks Thursday through its Beige Book, that carefully curated collection of anecdotes from regional banks that serves the dual purpose of explaining reality and preparing the public for whatever decision the central bank has already made. Investors will parse it for language suggesting rate pressure, the way religious scholars once searched texts for hidden meaning. Elsewhere, the Bank of Canada meets Wednesday with consensus expecting rates to hold at 2.25 percent, a posture of patience that reflects neither confidence nor courage. The Reserve Bank of New Zealand also decides this week, adding another data point to the global tapestry of central banks trying not to overreact.

But inflation is the story that won't be ignored. Eurozone CPI for August is expected to accelerate to between 3.3 and 3.4 percent annually, up from 2.9 percent in July. That jump alone may force the European Central Bank's hand at its September 16 meeting, according to most forecasters. It is the kind of number that renders discussions of "data dependency" technically true but strategically useless—the ECB will hike because it will have to appear to be doing something.

Switzerland and South Korea report their own inflation figures this week, part of the global price-pressure story that no central bank can credibly ignore anymore. When developed economies from Europe to Asia all see price acceleration simultaneously, the synchronized-shock narrative becomes harder to dismiss as transitory. This is the inflation narrative that proved resilient: it stopped being a supply-chain problem and started looking like a demand problem, which is what keeps policymakers awake.

Fed Chairman Kevin Warsh already signaled the thinking in his speech at the Kansas City Fed's Jackson Hole symposium, noting that inflation remained a key concern and that interest rates may need to rise in coming months. Deutsche Bank analysts have assessed that a rate hike at the September 16 FOMC meeting is the most likely outcome. Translation: the market is pricing in tightening because the central bank has already telegraphed it. This week's data will either confirm that script or force a rewrite.

Asia adds texture. China releases manufacturing and services surveys. Japan offers central bank commentary. Australia reports growth data. The ISM Manufacturing index arrives Tuesday, forecast between 55.8 and 56.4, while ISM Services follows Thursday. None of this will resolve anything definitively. Instead, it will provide fodder for conflicting interpretations, the raw material from which market participants construct whatever narrative best suits their existing positions.

This is what happens when central banks have collectively announced that data dependency is their governing principle: markets become obsessed with data, central banks become slaves to the narrative they've created, and the week ahead becomes a gauntlet of information that everyone will interpret differently on Friday than they did on Monday. The economic calendar is now the economy.
