Turkey's central bank hiked its key interest rate by a larger-than-expected 750 basis points to 25% on Thursday, sparking a rare lira rally and signalling a new determination to address rebounding inflation as part of a broader policy U-turn.
The surprise move leaves the policy rate at its highest level since 2019, and sent the Turkish currency to its strongest level since mid-July. The bank has raised its one-week repo rate (TRINT=ECI) by 1,650 basis points since June.
The policy committee - including three members taking part for the first time and seen as having hawkish sway - repeated it would tighten "as much as needed in a timely and gradual manner" to cool inflation, which soared to nearly 48% last month.
Analysts said the move was the clearest step yet toward more orthodox policies after years of unorthodoxy under President Tayyip Erdogan, and should help rein in inflation expectations.
The lira had touched new all-time lows almost daily in recent weeks, including in the minutes before the policy decision. But it jumped more than 3% versus the dollar afterward and was at 26.41 at 1205 GMT.
Turkish bank stocks rallied nearly 10%, lifting the broader Istanbul bourse, while the government's dollar-denominated bonds jumped more than 2 cents according to Tradeweb data.
The poll, conducted last week, showed that interest rates were not expected to rise to 25% until year end.
The rate hike "sends a very strong signal that the (bank) is determined to rein in inflation and the initial market response is very positive," said Piotr Matys, senior FX analyst at In Touch Capital Markets.
However, he said, "at least some investors will be wondering whether the 750bps hike has been approved by President Erdogan."
TURNAROUND
Erdogan appointed former Wall Street banker Hafize Gaye Erkan to head the central bank in June after his May re-election, in the face of an economy strained by depleted FX reserves and soaring inflation expectations.
He named three new policy makers - Osman Cevdet Akcay, Fatih Karahan and Hatice Karahan - to the bank in July in another signal that independent economists would more forcefully tackle inflation, which has held well above the official 5% target for years.
Erdogan's past drive to slash rates sparked a currency crisis in late 2021 and sent inflation above 85% last year. Annual consumer prices are seen rising to around 60% by year end due partly to currency depreciation.
The central bank said that rising oil prices and a deterioration in inflation expectations suggests that inflation will end the year at the upper bound of its forecasts. Still, "disinflation will be established in 2024," it added.
The currency is down about 68% in two years largely due to Erdogan's previously outspoken opposition to high rates and influence over the central bank. It crashed again this summer as the new economic team in Ankara loosened the state's grip on FX markets and began shedding unorthodox policies and regulations.
The central bank has also selectively tightened credit. At the weekend it began rolling back a costly scheme, adopted to halt the late-2021 currency crash, that protects lira deposits against forex depreciation.
