---- Has Google turned the dial down in anchor text keywords?

Also, this particular keyphrase was hit only on a regional Google... SERPs on Google.com were unaffected.
Meaning whatever this is, it's a LocalRank issue, at least for us. Our site has enough TrustRank while its LocalRank parameters were pretty low to start with ( not hosted in the country, not having the proper .tld, default is English which is not the language for the region... etc. ).
...and yes, as tedster points out, that word "local" can be confusing. ;)
Apart from the terminology of LocalRank, Miamacs analysis of his geo-regional drop is a good one.
I'm also seeing the filter dials being tuned constantly, and they can relate to link quality (including filtering designed to identify purchased links), anchor text patterns, apparent link-network patterns, phrase-specific duplication issues, etc etc.
