OFZs (abbreviation for Russian: Облигации Федерального Займа, romanized: Obligatsyi Federal'novo Zaima, lit. 'Federal Loan Obligations') are coupon-bearing federal loan bonds issued by the Russian government. The Ministry of Finance auctions off OFZs to finance the federal budget, or less commonly, to bail out troubled banks. Given their role, they form an essential part of the Russian financial system.
OFZs were introduced in June 1995 to complement the GKO market as an instrument with medium and long-term standing. Inflation-linked OFZ bonds are also issued. In August 1998, the Russian government defaulted on domestically issued debt, including OFZs. In 2012, OFZs were connected to the pan-Europe settlement and clearing system Euroclear.
The share of foreign-held OFZs increased from nearly zero in 2006 to 25% by the end of 2013. As of February 2018, 33.9% of all outstanding OFZs were held by foreigners. By September 2018 the number had dropped to 27%, due to the threat of further US sanctions against the Russian economy.
