Regarding the impact of a 1% increase in energy commodity prices (see Chart 6), except for
the direct effect on PPI energy, the effect is rather muted. According to the result, the impact
amounts to an increase by 0.27% on PPI energy after 4 quarters, by 0.022% in PPI
intermediate and 0.008% in PPI consumer goods. Regarding the impact on consumer prices,
the impact is rather similar for non-energy industrial goods and services prices (around
0.005% after 16 quarters), while it is stronger for processed food prices (about 0.012%) , with
an overall slower pass-through compared to producer prices. Using the weighted average for
the CPEX suggests an impact of 0.006%. It should be noted that the present study only looks
into the indirect effect on the non-volatile components of the HICP, while the direct effect on
the HICP energy would be significantly stronger and more immediate. A rule of thumb would
suggest that a 1% increase in oil prices would lead to a 0.01-0.02% increase in total HICP due
to the direct effect of oil prices.11 A somewhat astonishing fact is that the effect on processed
food prices is about twice as large as that on the other consumer prices which is due to a
stronger impact of PPI energy and intermediate goods on this component of the HICP. This
may reflect the relatively high energy content in food production.

PPENE: PPI energy; PPINT: PPI intermediate goods; PPCONS: PPI consumer goods; CPFDPR: HICP
processed food; CPNEIG: HICP non-energy industrial goods; CPSERV: HICP services, CPEX: HICP excluding
unprocessed food and energy.
The impact on consumer prices according to our models is roughly in line with that of
different macro-models when taking into account the fact that we only consider the HICP
excluding unprocessed food and energy here. In particular, the ECB AWM, the EC QUEST,
