ECB with a "Wait-and-See" Bias - Even When the House is on Fire
When "Data-Dependence" Becomes an Excuse for Inaction
The European Central Bank (ECB), like many of its peers, frequently reassures the public and markets that it is “data-dependent.”
The phrase is meant to signal discipline, objectivity, and responsiveness. But in practice, this data-driven approach has begun to resemble a form of institutional inertia - especially when the data itself is late, noisy, or misleading.
Germany's Federal Statistical Office recently revised its GDP figures, revealing that what had previously been described as mere “stagnation” was, in fact, the longest recession in modern German history: 8 consecutive quarters of zero or negative growth up to Q2 2024. For two full years, Europe’s largest economy was effectively in decline - and yet this reality was not acted upon, because the data at the time didn’t quite say so.
This revision is not just a statistical curiosity, as Heiner Flassbeck explains in detail. It exposes a deeper problem with how central banks interpret their mandates. In a world of real-time shocks, delayed data revisions can lead to devastating policy errors. A central bank that waits for confirmed evidence of a slowdown is already too late.
The supposed virtue of “data-dependence” is that it keeps policy grounded in observable facts. But this principle becomes dysfunctional when policymakers rely on lagging indicators, such as GDP and headline inflation, while ignoring broader signals from the labor market, business surveys, or credit conditions. Even worse, by clinging to a narrative of “wait and see,” ECB risks becoming passive observers rather than active stewards of the economy.
Moreover, “data-dependence” offers no clear rules. Which data? How much deviation from forecasts is needed to prompt a response? Without this clarity, the mantra becomes a rhetorical shield against criticism. It allows policymakers to avoid difficult decisions by deferring to the data - even when the data itself is ambiguous or incomplete.
Markets, too, are left confused. In recent quarters, forward pricing has consistently anticipated interest rate cuts, while the ECB pushed back, citing “insufficient evidence.” This mismatch undermines trust in central bank communication, weakens forward guidance, and leaves fiscal authorities unsure how to calibrate their own responses.
There is also an asymmetry of risk that data-dependence ignores. Acting too soon might carry political or reputational risk, but acting too late can entrench real economic damage - from business closures to long-term unemployment and declining investment.
What Europe needs is not a central bank that follows data blindly, but one that uses data wisely - as part of a broader, risk-aware judgment. Policy should be forward-looking, responsive to credible trends, and brave enough to move before every indicator turns red.
Sometimes, being “data-dependent” is just another way of saying:
“We chose not to decide.”
