President Vladimir Putin's economic adviser criticized the central bank on Monday after the ruble plunged past 101 against the U.S. dollar, blaming its 30% year-to-date slump on loose monetary policy, revealing growing discord among Russia's monetary authorities.

The ruble has lost around a quarter of its value against the dollar since Putin sent troops into Ukraine in February 2022, as Western sanctions shrink Russia's balance of trade and military spending soars.

It hit 101.7475 per U.S. dollar on Monday, its weakest point in almost 17 months and 30% down so far this year. Based on the cross rate, the year-to-date fall was 26.2%.

Putin's economic adviser Maxim Oreshkin said the central bank could ensure that the pace of lending drops to sustainable levels with higher rates. High consumer lending, along with a stark labor shortage and wide budget deficit have all fanned inflation this year.

"The main source of ruble weakening and accelerating inflation is soft monetary policy," Oreshkin wrote in an op-ed for the TASS news agency. "The central bank has all the tools to normalize the situation in the near future."

The Bank of Russia's next scheduled interest rate decision is on Sept. 15. Asked whether it might make an emergency hike from the current 8.5%, it declined to comment.

In a later statement, the bank said it would meet on Tuesday to discuss the key interest rate.

"On Tuesday, 15 August 2023, the Board of Directors of the Bank of Russia will hold a meeting to consider the level of the key rate," the central bank said in a statement.

Oreshkin said a strong currency was important for the economy. "A weak ruble complicates the economy's structural transformation and negatively affects the population's real incomes," he said.

The central bank has blamed the ruble's slide on Russia's shrinking current account surplus – down 85% year-on-year in January-July. On Monday, the bank said it saw no financial stability risks from the ruble's weakening but that a rate hike was possible soon.

Higher interest rates would make life harder for borrowers, including companies and the government as it finances military operations in Ukraine.

'Laughing at us'

Central Bank Governor Elvira Nabiullina won plaudits for her handling of the economy in the immediate aftermath of Russia's invasion, but she may be being lined up as a scapegoat ahead of next March's presidential election, as the weak ruble and stubbornly high inflation hurt consumers.

Popular pro-Kremlin television presenter Vladimir Solovyev, whose Rossiya 1 shows are watched by millions of Russians, launched into an aggressive, expletive-ridden criticism of the central bank late last week.

"...every other country is laughing at us, at our ruble being one of the three weakest currencies, thanks to the 'genius' policy of the central bank," he said.

The ruble has chartered a turbulent course since Russia invaded Ukraine, slumping to a record low of 120 against the dollar in March last year before recovering to a more than seven-year high a few months later, supported by capital controls and surging export revenues.

In the year leading up to the war, the ruble traded at around 74 to the dollar on average, with its movement dictated by factors like prices for oil, Russia's major export, and susceptibility to sharp geopolitics-induced swings.

'Damning indictment'

"The weaker ruble is a damning indictment of Russia's war on Ukraine," Timothy Ash, a London-based senior sovereign strategist at BlueBay Asset Management, said in an email.

"It is being driven not only by lower energy receipts due to the loss of the bulk of the European gas business but also by the success of the G7 oil price cap, the much higher cost of imports due to sanctions and then continued capital flight."

Last week, Russia effectively abandoned its budget rule, with the central bank halting the finance ministry's FX purchases to try to reduce volatility. Analysts widely agreed that those measures alone were too minimal in scope to significantly support the currency.

"The central bank is not fully in control," independent Moscow-based economist Ian Melkumov told Reuters, although it has aggressive tools that it is currently reluctant to use.

He said the bank could hike rates drastically, as it did to 20% shortly after Russia began what it calls a "special military operation" in Ukraine. A move to even 15% would stop the ruble's decline, he said, but it would come at a price.

"The central bank doesn't want to kill the economy and businesses in the same way it had to last year," he said.
