Credibility at Stake: Why the Fed May Need to Raise Rates in September to Avoid a Monetary Policy 'Anna Karenina' Failure

Deep News08-02 18:09

Following Fed Chair Jerome Powell's first press conference, market skepticism about the central bank's commitment to fighting inflation is growing. Bank of America Securities warns in a recent report that monetary policy now faces an "Anna Karenina principle" scenario—success requires multiple conditions to be met simultaneously, while failure in any single critical area could derail the goal of price stability.

After the Fed voted 9-3 to hold rates steady, Powell did not provide a sufficiently clear policy explanation, instead emphasizing that the market has already tightened financial conditions, partially substituting for the effect of rate hikes. This statement has triggered a market repricing: longer-end yields have risen, the yield curve has steepened, breakeven inflation rates have widened, and the dollar has weakened—a classic market reaction to a central bank under credibility pressure.

Bank of America believes that if inflation data over the coming weeks fails to provide clear dovish support, a September rate hike may no longer be just a policy option, but a necessary step to reclaim market trust and repair policy credibility.

Powell's Remarks Fuel Doubt: Is the Fed Passively Following Markets or Actively Anchoring Inflation?

Powell's comments at the press conference sent a complex signal. On one hand, he argued that financial markets have already proactively tightened conditions, meaning the Fed does not need to achieve the same effect through further rate hikes. On the other hand, he hinted at the possibility of referencing more inflation indicators and considering tools beyond rate hikes to address price pressures.

Bank of America points out that the problem lies in the divergence of Powell's policy logic from traditional central bank communication frameworks.

Former Bank of England Governor Mervyn King's "Maradona theory of interest rates" suggests that central banks guide markets to preemptively tighten financial conditions through policy expectations, thereby reducing the pressure to raise rates themselves. Powell's statement, however, is closer to a different logic: the market adjusts interest rates on its own, and the Fed simply observes and follows.

But Bank of America warns that this logic carries risks. A rise in long-end rates does not necessarily mean financial conditions are genuinely tightening; it could also reflect a market repricing of higher fiscal deficits, stronger economic growth, higher risk premiums, or elevated inflation expectations.

The market's movement following the press conference reflects this concern: rising long-end real rates, widening breakeven inflation rates, and a further steepening of the yield curve suggest that investors are beginning to doubt the Fed's ability to maintain long-term inflation anchoring.

Moderate Employment Growth Supports a Soft Landing, Strengthening the Case for a September Hike

Bank of America expects the U.S. to add 80,000 non-farm jobs in July, slightly below market expectations, but private sector payrolls are forecast to increase by 95,000, up from 49,000 in June.

The report believes the current labor market shows no clear signs of deterioration. Initial jobless claims remain moderate, and job growth is ongoing. While summer seasonal factors, weak ADP employment data, and slower local government hiring pose risks, the overall trend still supports a soft landing for the economy.

Regarding the unemployment rate, Bank of America expects it to rise from 4.2% in June to 4.3%, mainly due to a rebound in the labor force participation rate. On wages, average hourly earnings are forecast to rise 0.3% month-over-month in July, with the annual rate holding steady around 3.5%, showing no clear inflationary pressure.

Bank of America argues that if the employment data meets expectations, it would mark the fifth consecutive month of non-farm payroll growth, bringing the average monthly private sector job additions in 2026 to about 89,000 and further reducing downside risks to the labor market.

Against the backdrop of a still-resilient job market and persistently sticky inflation, Bank of America believes the rationale for the rate-cutting cycle from last year is weakening, while the policy basis for a September rate hike is strengthening.

Under the 'Anna Karenina Principle,' the Fed Faces a Test of Credibility

Bank of America uses the classic opening of Tolstoy's *Anna Karenina* and the "Anna Karenina principle" coined by economist Jared Diamond to explain the current predicament facing the Fed. This principle holds that success requires all necessary conditions to be met, while failure often results from the absence of just one critical condition.

For monetary policy, achieving price stability requires not only the interest rate tool, but also central bank credibility, stable inflation expectations, fiscal policy coordination, and financial system stability, all working in tandem.

Bank of America notes that monetary policy is not a pure mathematical model, but an art reliant on communication. The core task of a central bank press conference is to make the market understand its policy reaction function; if this fails, uncertainty is transferred to the market, potentially leading to a de-anchoring of inflation expectations.

The problem with Powell's latest press conference is precisely that he did not clearly explain how the Fed will balance growth, employment, and inflation in the future.

Bank of America believes the Fed still has an opportunity to regain control of the market narrative, and the September meeting will be a critical juncture. If incoming data does not prove that inflation is rapidly declining, a rate hike may become an essential step for the Fed to repair its credibility and re-establish a policy anchor.
