Turkish financial markets endured a turbulent week, marked by a steep decline in equities and renewed pressure on the national currency. The benchmark BIST 100 index closed Friday's session at 12,792.81, representing a daily loss of 2.19%. This drop capped a difficult period for investors, with the index retreating from a level of 13,717.81 just one week prior.
Central Bank in Focus Amid Inflation Battle
The Central Bank of the Republic of Turkey is scheduled to hold its monetary policy committee meeting on March 12. A recent survey of economists indicates a strong consensus that the bank will maintain its key policy rate at 37%, signaling a pause after a prolonged tightening cycle. This expectation has removed a potential support for the lira, which is highly sensitive to interest rate differentials.
Official data revealed that consumer price inflation accelerated to an annual rate of 31.53% in February, up from the previous month. Finance Minister Mehmet Simsek acknowledged the challenge, stating that authorities are working to mitigate the inflationary impact stemming from higher global oil prices due to geopolitical tensions.
Currency and Commodity Pressures Mount
The Turkish lira weakened considerably throughout the week, breaching the psychologically significant 44 level against the U.S. dollar. It touched a historic low of 44.0750 by Friday. In response, the central bank intervened aggressively in the foreign exchange market, with estimated sales reaching approximately $13 billion for the week. This action caused overnight lira funding rates to spike above 40%, surpassing the main policy rate.
Concurrently, the price of Brent crude oil, a critical import for Turkey, soared to $88.9 per barrel. This represents a substantial increase from $72.65 just seven days earlier, directly raising the nation's energy import bill and exacerbating inflationary pressures.
Broad Market Selloff and External Context
The downturn was broad-based, with the banking sector leading losses. Reports indicated the BIST banking index plummeted nearly 5% at the start of the week. By Friday's close, only 25 constituents of the BIST 100 finished in positive territory, while 74 ended lower. The total market capitalization of the benchmark index contracted from 13.59 trillion liras to around 12.6 trillion liras over the week.
The selling pressure extended beyond Turkey's borders. The MSCI Emerging Markets index shed over 6%, and Europe's STOXX 600 declined 5.5% during the same period. However, Turkey's acute dependence on imported energy magnified the domestic impact of the oil price shock, particularly as hopes for imminent interest rate cuts faded.
Institutional Perspective and Underlying Risks
Despite the market turmoil, some institutional voices urged perseverance with current economic policies. Odile Renaud-Basso, President of the European Bank for Reconstruction and Development, encouraged Turkey to "stay on course" in its battle against inflation. She noted that the EBRD's investment in the country is expected to remain "very high" this year.
Nevertheless, significant risks persist. Prolonged geopolitical instability, particularly tensions involving Iran, could keep energy prices elevated for an extended period. This scenario would constrain central banks' ability to ease monetary policy and continue to fuel inflation concerns. Renaud-Basso warned that such conflict "can reduce risk capital," emphasizing that "the risk is on the downside" for the economic outlook.
All eyes are now on the upcoming central bank decision. Analysts from institutions like HSBC anticipate a hold on rates. The critical question for markets will be whether policymakers commit to maintaining tight liquidity conditions to defend the lira, or suggest that last week's volatility can be managed without further aggressive measures.
