Switzerland also has the highest level of household debt (which includes mortgages) in the world. Lending volume and price usually have a fairly linear correlation.

The volume tied to mortgages is high compared to other countries because you can essentially keep 2/3rd of the debt forever, and even more if you indirectly amortize through your pension fund.
One important difference between Geneva and Denmark though - Genevas extremely expensive housing market (in both purchase and rent prices) is driven by its geographical location. It's surrounded by mountains on most sides and sitting on a lake. This means there's pretty much no space to build more buildings to accommodate the influx of people moving there to work in science and politics.
Geneva building prices were skyrocketing without those loans just because there was no way to build more.
