A7A5 is an RUB stablecoin issued by Old Vector (A7A5), launched on 28 Jan 2025.
A7A5 is a ruble-denominated token issued by Old Vector LLC, a company registered in Kyrgyzstan. The US sanctions list gives Old Vector's establishment date as 13 December 2024. Kyrgyzstan's financial market regulator, Finnadzor, lists an Old Vector issuance in its state register of virtual asset issues. The regulator told Kyrgyz outlet Akchabar that it registered the issuance of 100 billion A7A5 tokens on 19 February 2025, against 100 billion rubles.
The US Treasury designated Old Vector LLC on 14 August 2025, alongside the exchange Grinex and A7 Limited Liability Company. Treasury states that the A7A5 token is issued by Old Vector and that Old Vector 'worked with Garantex and others in the creation of the A7A5 token'. Ownership sits one step away: Treasury says A7 and its subsidiaries are owned by sanctioned Moldovan oligarch Ilan Mironovich Shor and by sanctioned Russian bank Promsvyazbank. It does not say Shor owns Old Vector.

How far A7A5 trades from its RUB peg, from DIA's daily price reads.
Figures are in basis points: 100 bps = 1%.
Peg volatility is how much A7A5's price swings around 1 RUB from one day to the next: the standard deviation over 30 or 90 days. A stablecoin that sits steadily at 0.998 RUB scores near zero. Largest deviation is the single day in the last 12 months furthest from 1 RUB, signed.
The ranking counts every active RUB stablecoin with at least two daily prices in the last 90 days.
Prices are daily closes at 00:00 UTC, from DeFiLlama with CoinGecko where DeFiLlama has no price. The chart beside this panel plots those same daily closes, so every figure in the table can be found on a line here. DeFiLlama quoted rounded and filled prices until 30 September 2025, so for USDT and USDC the closes before 1 October 2025 are the median of exchange closes instead, and a filled US$1.0000 close is left out of the typical move and the largest move.
Stablecoins whose value rises by design, such as savings wrappers, are left out. Their price is a yield curve, not a peg.
Only USD stablecoins are compared. Other currencies are priced through a daily exchange rate fixed at a different time of day from the stablecoin's close. That gap shows up as the same false depeg on every stablecoin of the currency at once.
For a RUB stablecoin, the largest deviation leaves out days when most other RUB stablecoins closed the same distance from par on the same side: that move is the exchange rate, not A7A5. A move A7A5 makes alone, or a discount it holds while the others stay at par, is kept.

Activity in A7A5 has fallen sharply. Elliptic reported daily transaction volume of $24.3 million in June 2026, down 96% from the July 2025 peak, and recorded no new minting of the token since July 2025.

From late September 2025, users reported that USDT received from swapping A7A5 was frozen or flagged on arrival at global exchanges.

A7A5 is designed to be backed by cash and money-market assets.
There is no published reserve attestation for A7A5. The transparency page on the A7A5 website shows tokens in circulation by network and links a smart contract audit report. It gives no reserve figure.
What exists instead is two accounts of the backing.
Neither statement is a reserve report. Neither names a custodian account, a balance, or an independent party that verified one.

Who licenses A7A5's issuer and how its reserves are reported.
The United States, the United Kingdom and the European Union acted against A7A5 and the entities around it.
The EU measure goes further than the US and UK actions because it names the token itself.
On the Kyrgyz side, Finnadzor's register lists Grinex as a virtual asset exchange operator, and the regulator said Grinex "is not an operator of virtual asset trading".

We checked the issuer's disclosure pages and found no reserve attestation. Coins we have not checked carry no value here at all.
Registered elsewherelicence tier of Old Vector (A7A5)
Sanctions exposure. EU persons are prohibited from transacting in A7A5 directly or indirectly. The issuer is designated in the US and listed in the UK.
Downstream taint. Proceeds from swapping A7A5 into USDT were reported frozen or flagged at global exchanges from late September 2025.
No verifiable reserve. No reserve attestation is published. Chainalysis and the Swiss sanctions listing name Promsvyazbank deposits, while Finnadzor said Old Vector itself carries out the financial backing. A holder cannot check either claim.
Primary venue outage. Grinex was the primary trading venue, and it lost bank-card top-ups on 4 April 2026.
Frozen issuance. Elliptic recorded no new A7A5 minting after July 2025.

Old Vector LLC, a company in Bishkek, Kyrgyzstan, established on 13 December 2024 according to the US sanctions list. Kyrgyzstan's regulator Finnadzor said it registered the A7A5 issuance on 19 February 2025. The company is tied to the Russian settlement firm A7 LLC.
Yes. OFAC designated Old Vector LLC, Grinex and A7 LLC on 14 August 2025, Old Vector was added to the UK sanctions list on 20 August 2025, and the EU's 19th package adopted on 23 October 2025 prohibits any transaction involving the A7A5 token.
No reserve attestation is published. Chainalysis describes the backing as ruble deposits at Promsvyazbank, while Kyrgyzstan's Finnadzor said the financial backing is carried out by Old Vector itself.
