EMRE DELİVELİ > Braveheart ROCs Central Banking

Print Page Send to friend »

During a speech on Friday, Central Bank Governor Erdem Başçı underlined that it would take a (brave) heart to implement the Bank’s latest tool, Reserve Option Coefficients (ROCs).

Commercial banks have been allowed to keep some of the lira reserves they are required to maintain at the Central Bank in foreign currency (FX) for a while. At the end of May, the Central Bank increased the upper limit of this option to 45 from 40 percent of total required reserves. It also noted that this last 5 percent would have to be multiplied by a coefficient of 1.4. So 100 liras of reserves could be replaced with 140 liras worth of euros or dollars.

Since then, the Bank has not only increased the upper limit gradually to 60 percent, it has also introduced different ROCs at different tranches. While it cut its lending rate by 1.5 percent at the latest rate-setting meeting on Tuesday, the Central Bank also increased all ROCs by 0.2, which now vary between 1.3 in the first tranche of 0-40 percent to 2.2 in the final tranche of 55-60 percent and have emerged, along with the interest rate corridor, as the primary policy tool.

You might wonder why banks would want to keep more money as reserves that don’t pay out any interest- the simple answer is that it is cheaper to borrow FX than lira. In fact, you can find the threshold FX interest rate for each tranche by dividing the cost of Central Bank funding by the ROC. Since that rate is currently 6.1 percent, banks would want to utilize the option in full for the first tranche as long as they can borrow in FX at lower than 4.7 (6.1/1.3) percent.

Of course, this is only a very rough calculation, which assumes banks can get as much foreign funding as they want. But the more interesting question is why the Central Bank would want to implement such a scheme. For one thing, it would take some pressure off the lira if the country is exposed to strong capital inflows resulting from the global easing by the major central banks.

In fact, ROCs can work both ways. When this hot money stops or reverses, banks could tap their FX reserves at the Central Bank. In this sense, the Bank sees its new tool as an automatic stabilizer. While it could indeed decrease FX volatility, I am not sure if this novel system could withstand a major crisis. Besides, I wonder if it is making Turkey more vulnerable by encouraging foreign borrowing.

Başçı noted that that having FX parked at the Central Bank makes it easier for banks to borrow from abroad, and they have indeed resumed getting foreign loans. That’s when I started getting confused. I thought the Bank did not want dollarization and currency mismatches in the first place. The ratio of short-term debt to reserves, one of the Bank’s reserve strength indicators, is already above one.


My confusion grew when he emphasized that only central banks not paying interest on reserves could implement ROCs, and that required guts, or a brave heart. I could not figure out the relationship, so I consulted a Turkey economist as well as a couple of central bankers. They could not, either.

The Central Bank’s new tool indeed ROCs. I hope adding another layer to the already-complex set of policies does not make us also roll.

Emery Bey, I always enjoy your column even though I am not too sophisticated in the world of economics & finance. You seem very knowlegeable and have a good handle on what's happening in the country. In the back of my mind however, I always wonder if "Greek Style" accounting is often taking place in government circles. Unfortunately, we never know until it's too late. Please keep up the good work and your independent analysis of the facts as you see them.

Cost of borrowing in the EU is peanuts compared to Turkiye because they are all suffering from double dip recession.Turkiye is money hungry country and its only natural and healthy to take the slack out of European lending by upping our ever increasing demands.We need it we can use it optimally.
