Russia has hiked interest rates to 12% after the rouble fell to its lowest value in 16 months.

The rouble fell past 100 per US dollar on Monday, prompting Russia’s central bank to hold an emergency meeting.

The Bank of Russia said it decided to raise interest rates from 8.5% to curb inflation, which hit 4.4% in August.

Pressure has been mounting on the Russian economy due to imports rising faster than exports and military spending growing for the Ukraine war.

“Steady growth in domestic demand surpassing the capacity to expand output amplifies the underlying inflationary pressure and has impact on the rouble’s exchange rate dynamics through elevated demand for imports,” the Bank of Russia said in a statement.

The bank said “inflationary pressure” was building, but that its target was to bring inflation, which is the rate prices rise at, down to 4% by 2024.

Russia has been targeted with sanctions by Western countries following its invasion of Ukraine in February 2022.

Its currency, the rouble, plummeted after war first broke out, but was bolstered by capital controls and oil and gas exports.

However, it has lost about a quarter of its value overall against the dollar since Ukraine was invaded and this week more than 100 roubles was needed to buy one US dollar.

On Tuesday, the rouble recovered slightly, but remains much weaker than it was last year.

It is not the first time the Bank of Russia has been aggressive with interest rate hikes. When Russia first attacked Ukraine the bank raised rates from 9.5% to 20%, but began cutting them shortly afterwards.
