Understanding why financial markets don't always respond to data releases

Major economic indicators are among the most anticipated events in financial markets. Reports on inflation, employment, business activity and similar metrics can shape views on monetary policy and the broader economic outlook. However, markets do not consistently respond to such data in a uniform manner.

The crucial point to grasp is that financial markets operate with a forward-looking perspective. Asset valuations are driven by expectations regarding future economic conditions, central bank actions and related factors. Present conditions are not the focus. How markets react to an economic report depends on whether it alters those underlying expectations.

Not every economic release holds the same weight. For instance, an employment report that exceeds forecasts may initially push bond yields higher. Yet, if inflation is concurrently falling and the central bank grows more worried about undershooting its inflation target, the jobs surprise may not suffice to shift interest rate expectations.

The reverse scenario is also possible. A modest inflation surprise could have a substantial impact if market participants believe it will alter the central bank's next policy step.

Central banks generally determine which data matters most

Policymakers track a broad array of economic signals, but the significance of each indicator shifts with the economic backdrop. When inflation is the primary concern for a central bank, markets become highly responsive to price data such as CPI, PPI, wage growth and similar measures. When the spotlight moves to the labour market, jobs figures like NFP, jobless claims and others take on greater importance.

Thus, the relative importance varies depending on the economic environment and the central bank's priorities. For example, if the Federal Reserve is concerned about stubborn inflation and has hinted that further tightening may be required, a surprisingly strong inflation report could provoke a pronounced hawkish repricing. A weak consumer confidence report might have minimal or no effect because it does not relate to the Fed's immediate worry.

This explains why central bank communication is so critical for markets. Officials often signal which economic variables they are watching most closely. Traders then shift their attention accordingly, making some releases more capable of moving markets than others.

Positioning also matters

Market positioning can also influence how prices respond to economic data. If traders already anticipate a specific outcome, a report that confirms that expectation may generate little or no reaction. This occurred during the initial months with CPI reports, as markets had already priced in an inflation spike caused by rising energy costs linked to the US-Iran war.

This effect can become even more pronounced when positioning becomes overcrowded. If traders are heavily positioned for a particular outcome and conditions shift, the repricing of expectations can produce large market swings as participants hurry to adjust their holdings.

A relevant example is tomorrow's US PPI release. The report arrives after two key developments have already significantly altered market expectations for monetary policy.

First, Fed Governor Waller delivered very hawkish comments, supporting a December rate increase and raising the prospect of an even larger move if inflation data surprised on the upside. Then, the US CPI report came in above expectations, confirming the case for a December rate hike and increasing the likelihood of a 50 basis point move.

This suggests that tomorrow's PPI report is unlikely to trigger a large market response, because it would not change current expectations, even if the data comes in above forecasts. Most of the hawkish repricing has already occurred, leaving little room for additional adjustments.
