As of yesterday, it was 1:112, already sharp decline in RUB value compared to pre-war/pre-sanction levels of ~1:80. Now it's 1:158.

What changed in the last 24 hours? I'm no expert, but apparently, this lines up with Moody's downgrading of Russia's credit rating to Ca:

> *Moody's said default risks had increased, and that foreign bondholders were likely to recoup only part of their investment.*

> "The likely recovery for investors will be in line with the historical average, commensurate with a Ca rating," it said. "At the Ca rating level, the recovery expectations are at 35 to 65% (of face value)."
