They just print marginally slower than the rest of central banks. But yes, it's increadibly hard to get credit in Switzerland, interest rate are still low, at least for mortgages, but this drive housing price at crazy high levels. You still need to justify income to cover 5% interest when it's effectively at 1% or less, with 5 rooms house averaging at 1.25MCHF (~1.55MUSD) and around large cities it's more like 1.5 to 2MCHF up, you can clearly not afford one with a top level engineer salary or even mif level banker cannot afford. Only chance is to be in couple and both working 100% with mid to high level jobs (fuck family life) to have a slightly chance to qualify for a mortgage.
