Western European cities flood, most recently in 2021. The short list of low-risk high-GDP countries is limited to city states and the likes of Hungary, Czechia, Qatar, Denmark, Switzerland, Austria, Finland and Iceland [1]. Worldwide.

From that list:
4 Luxembourg 0.52%
13 Switzerland 1.03%
88 Germany 3.92%
110 United Kingdom 5.78%
131 Spain 9.68%
168 United States 22.73%
Though this does definitely tell me I was wrong about Australia, and that it only looks safe from a distance because the news isn't reporting on it:
164 Australia 21.36%

Hungary is quite nice though. Also, I'll take the Balkans over Western Europe any day. Not Bosnia or Kosovo, but the other EU countries, maybe even North Macedonia or Serbia. Or Southern Italy if you also want to be sophisticated.
There's evidence that the current is already slowing [1], and the midpoint of estimates for when it might collapse is at 1.8C warming, something we seem pretty likely to blow past within a decade or two.
It'd be bad for Australia and the Southwest US as well, since collapse of the AMOC would bring permanent La Nina conditions.
