According to NBC, Russia is not able to sell government bonds in the US and some European countries, after invading Ukraine:
Tuesday’s sanctions also barred the Russian Central Bank from financing in the U.S. and some European countries, meaning Russian government bonds can no longer be sold in many Western markets, causing their values to plummet.
I am wondering about which actual European countries still allow Russian government bonds. This is particularly interesting since virtually all EU countries seem to favor SWIFT disconnection.
