It's been a while - almost a year, in fact - since we touched base with one
of our favorite pointers on Euro-zone economic growth, Belgium's so-called
leading indicator. The number for September was enough of a surprise that it's
worth a quick re-visit.
To recap, this indicator - formally called the Belgian National Bank's Business
Confidence Survey - is based on three indices that measure current patterns
and future prospects in Belgian manufacturing, construction, and commerce.
It's worth monitoring because of what it tells us about growth prospects in
the wider Euro-zone. Belgium represents barely 4% of Euro-zone GDP, but some
75% of its own GDP is dependent on exports, and 80% of those exports go to
the other eleven members of the 'zone. In addition, little Belgium specializes
in making intermediate goods - things like chemicals, plastics, semi-conductors
and steel, which are used as inputs for both consumer or investment goods.
Any increase in demand for consumer OR investment goods will usually be preceded
by an increase in the output of intermediate goods.
All of this explains why Belgium's leading indicator is so closely watched
by economists - it has predicted future trends in Euro-zone GDP growth almost
perfectly for the better part of a decade, with about a three-month lead.

The main index recovered steadily from a decade-low -21.5 in June 2003 into
positive territory (just) in mid-2004, before sliding all the way to -12.4
in May of this year. Sure enough, Euro-zone GDP growth slowed steadily from
mid-2004 onward. During the summer months, the Belgian indicator didn't seem
to know whether it was about to recover or to slide anew. This month, it abruptly
recovered from -10.9 in August to -5.6 in September. Most of the boost came
from manufacturing, with that sector's sub-index jumping from a moribund -14.1
last month to -7.0 this month. Confidence in the sector reportedly was based
on heightened activity and a strong improvement in demand. Does this mean we
can expect an improvement in Euro-zone GDP in Q4?
The other indicator to watch, and the one favored especially by currency market
players, is the German business climate index released monthly by the Ifo institute.
The headline index measures the business climate in Germany, and is more of
a coincident indicator than a leading one. More attention focuses on the sub-index
that measures the business outlook for the next six months.

Germany is the Euro-zone's largest economy, accounting for almost a third
of the region's overall output. So, the Ifo index, and particularly the outlook
sub-index, should give a good impression oftrends for the area as a whole.
Like the Belgian leading indicator, the Ifo weakened in late 2004 and early
2005, but couldn't seem to make up its mind which way it was headed in the
summer months.
The September Ifo will be released on Tuesday, September 27. The ZEW research
institute index of investor confidence, released earlier this week, dropped
sharply to 38.6 from 50.0 in August. Obviously investors are unnerved by the
inconclusive German general election, but they are also concerned over soaring
oil prices and a slowdown in global growth. Are German businesses feeling similarly
anxious?
If Tuesday's Ifo turns south, markets and investors will assume that the Belgian
number was a one-month blip and that Q4 will be a weak one in the Euro-zone.
