High Nominal Rates Don’t Always Mean Restrictive Policy

A 5% policy rate can coexist with accommodative real financial conditions — provided inflation runs higher. The gap between the nominal headline and the real-terms reality is one of the most persistent sources of analytical error.

Central bank communication anchors itself on nominal rates. The economy responds to real rates. The two readings diverge often enough to make the gap structural, not anecdotal.

When the policy rate reaches 5%, the reflex is to call monetary policy restrictive. The same logic appears in the historical decoding of curve-and-market divergence. Yet if inflation runs at 6%, real conditions stay accommodative: borrowing costs less, in purchasing power, than the headline rate suggests. The gap between perception and reality is one of the most frequent analytical errors. It explains why some economies keep growing under apparently restrictive nominal rates, and why others stagnate when rates look moderate. The relevant variable is the real rate, not the nominal headline.

The gap in practice: two revealing configurations

The United States offers the recent textbook case. Between July 2023 and September 2024, the fed funds rate held at 5.25-5.50% — the highest level since 2001. Real GDP growth still reached 2.8% in 2024 according to the Bureau of Economic Analysis, and the labour market remained robust. The mechanism runs through real rates, provided the inflation measures are not mixed. Against core inflation, which falls from 4.7% in July 2023 to 3.2% in September 2024 (Bureau of Labor Statistics), the effective real rate starts at +0.4% and only clears +2% in the summer of 2024, averaging +1.5%. Against headline inflation it runs higher, between +1.6% and +2.7%. Either way the level is moderate by historical standards, where the real rate peaked at 5.0% in 1989 and 3.2% in 2000; but the one-point gap between the two conventions is a reminder that the figure means nothing without its inflation measure.

Japan offers the symmetrical case. With a policy rate held at 0.5% from January to October 2025, monetary policy looks ultra-accommodative on a nominal screen. But Japanese inflation has run near 3% since the start of 2024 (Statistics Bureau of Japan), averaging 3.0% with only three months below 2.5%, which keeps the real rate around -2.5%. The “normalisation” narrative attached to the nominal increase obscures the fact that real conditions remain looser than they were during most of Japan’s deflationary period. Reading the nominal-vs-real distinction at face value is the precondition for avoiding these inverted diagnoses.

Why the bias persists in commentary

The policy rate is a single figure, clearly communicated, immediately comparable across time and across central banks. The real rate requires an adjustment calculation and depends on the inflation measure chosen — observed, expected, headline, or core. The asymmetry of complexity explains why media commentary, market briefs, and at times policymakers themselves stick to the nominal figure. That shortcut sustains the family of reasoning errors that propagate around rates and inflation precisely because the nominal headline looks self-sufficient.

Central bank communication itself sustains the confusion. ECB and Fed press conferences anchor on nominal rates. Forward guidance is expressed in nominal terms. Projections are presented as nominal paths. The real rate appears implicitly, embedded in the accompanying inflation projections — a layer of reading only specialists reconstruct. The central scenario adopted by most observers rests on the nominal grid, which is why the economy keeps surprising commentary: it responds to the real rate, not to the headline figure quoted on the screen.

The diagnostic anchor sits in the real rate. A “high” nominal rate says nothing without the inflation context. A “low” nominal rate can be restrictive when inflation is even lower. This single filter rewires the reading of monetary conditions and makes it possible to assess liquidity conditions beyond the nominal headline that commentary tends to take at face value.

Update, September 22, 2026. The two cases have kept diverging. In Japan the policy rate has climbed to 0.98% in August 2026, but with inflation at 1.9% year on year (Statistics Bureau of Japan, August 2026) the real rate remains negative: nominal “normalisation” has yet to produce any real tightening. In the United States the move went the other way: with the effective policy rate unchanged since January, rising inflation pulled the real rate back to +0.3% in August 2026, after a spell below zero in April and May.
