> can be extremely hard to physically get to your savings money in a crisis
Having spare cash around is never a bad idea. But there are precious few timelines in which the banking system collapses so completely that savings are inaccessible for extended periods (or at all) but paper U.S. dollars continue to hold value.
No one expects it to hold 100% of value, but even 10% of say $50k could be very helpful to live through the few months of the turmoil. Or to get to that foreign real estate which people recommend buying in comments on HN.
Well it's one of the tail cases, so all things considered both local currency and foreign currencies are useful, each in it's own quality. So is a foreign currency in a foreign bank.
