Markets are split on the Turkish central bank’s next move, with expectations centred on either no change to the repo rate or a 300 bp rise. Corridor tightening is also described as tightening in practice.
The disinflation narrative is described as unconvincing, with inflation issues said to pre-date the current price shock. Policymakers are described as expecting an oil price shock to worsen conditions in coming months.
External balances are described as deteriorating, adding to pressure on the Turkish lira (TRY). The TRY exchange rate is described as heavily managed, which can limit near-term volatility.
A lack of tightening is described as a risk factor for a sharper TRY sell-off and a higher chance of abrupt adjustment. Measures such as limits on swap exposure or requirements for exporters to sell foreign-currency proceeds to the central bank are described as not substituting for monetary policy action.
The upcoming central bank decision presents a divided outlook, with markets split between holding rates steady and a significant 300 basis point hike. This uncertainty is creating a tense environment for the Turkish Lira, making the outcome a major catalyst for the weeks ahead.
We see the disinflation narrative as unconvincing, especially as recent data showed annual inflation stubbornly holding above 72% in March 2026. Furthermore, Turkey’s current account deficit widened to nearly $5 billion in February, signaling that external balances are deteriorating. These figures make the central bank’s choice all the more urgent.
The recent surge in global oil prices, with Brent crude now trading consistently above $95 a barrel, will only make this situation worse in the coming months. This external shock amplifies the already unsustainable inflation trend. We do not accept that the disinflation plan was working fine until this shock arrived.
We recall the aggressive rate hikes through much of 2025, which were meant to put inflation on a clear downward path. However, any failure to deliver significant tightening now would confirm market fears that political pressure is preventing the central bank from acting. Such inaction would be interpreted as an inability to control the situation.
For derivative traders, this binary outcome suggests a sharp increase in USD/TRY volatility is likely. Implied volatility in the options market is already trading at three-month highs, reflecting the tension. Strategies that profit from a large price move, regardless of direction, should be considered to position for the event.
If there is no significant policy tightening, we would be concerned about a sharper lira sell-off. The heavily managed exchange rate has smoothed volatility recently, but it cannot resolve the underlying imbalances. The probability of a more abrupt and disorderly currency adjustment will rise materially in the event of policy inaction.
