I did a research project into climate change and the risk it poses to banks in Switzerland. Switzerland had experience flooding in the past few years.
After digging through all the data, the issue wasn’t really climate change. Average rainfall didn’t increase at a statistically significant level.
The issue was….the Swiss are building too many houses in places they shouldnt. Near river banks and in the country side where green land used to be. It was something like new builds in certain areas in the past decade was like 200% more than the past few decades.
What was driving this increase? Well, the Swiss were losing money leaving it in the banks. Interest rates were negative so it drove the Swiss to invest money into real estate into the country side. What’s even more illogical is that the Swiss are leaving those places in droves to the cities so no one even lives in those places.
So basically, Swiss banks, are at risk of massive losses from flooding from all the mortgages and loans for land development in places they should build
