Well 90% of Us mortgages are fixed.
Of the ARM mortgages, nearly 90% of them have longer terms than 1 year.
You're looking at maybe 2% of mortgages that will be impacted unless rates stay this high for >2 years.
Everywhere else in the world beside Denmark, where there are ONLY ARM mortgages - they're gonna be in for a world of hurt if interest rates stay this high for >2 years...
