Interest rates on credit cards and vehicle loans in Qatar have gone up in the range of 0.32% to 1.16% (32-116 basis points) in 2016, a QCB report has shown. 
In line with the interest rates on deposits, weighted average interest rates on credit facilities for all maturities, except that for 1-3 years, increased somewhat during 2016; the increase ranging between 12-38 basis points, it said.
The broad success of QCB’s liquidity management strategy in ensuring a stable interest rate regime to support diversified economic growth was also evident from the behaviour of interest rates on customer deposits and credit facilities of banks. 
The weighted average interest rates on customer deposits for all maturities recorded some increase at the end-of 2016 as compared to end-2015 – the increase ranging between 0.28% and 0.69% (28 − 69 basis points), Qatar Central Bank said in its 8th Financial Stability Review.
Qatar interbank offered rate (QIBOR) introduced in May 2012 has been playing an indicative role for banks in determining interbank rates. 
QIBOR and interbank rates have generally co-moved since then, except in periods of market volatility. 
During 2016, while QIBOR and overnight rate showed similar trend, the overnight rate generally ruled above the QIBOR rate during the first half and below it during most part of the second half of the year.
During 2016, interest rates moved in line with the evolution of liquidity in the system as well as some hardening of inflation as compared to the previous year. 
QCB’s active liquidity management operations, however, helped in containing movement of interest rates in various segments of the financial market in a range bound manner.
In the money market, this was reflected in overnight rates, which eased during the first quarter as well as during June-July with the increase in liquidity surplus, QCB said. 
Following the moderation of surplus liquidity due to T-bonds auctions during August-October, overnight rates hardened somewhat during the fourth quarter of the year. The overnight rates increased in line with the increase in QCBDR and QCBLR by 0.25% (25 basis points) each to 1% and 4.75% respectively on December 15, 2016. 
Overnight rates generally ruled above the QMR deposit rate during the year, except in July 2016. 
In 2016, the overnight rate moved in a wider range of 0.74−1.66% and averaged at 1.16%, as compared with the range of 0.64−1.36% and average of 0.89% in 2015.
“There was some hardening at both end of the maturity spectrum for the overnight rate, and at the short-end for interbank rate, in 2016 as compared with 2015,” QCB said.
The evolving liquidity conditions were also reflected in the movement of T-bills yields during the year. 
After easing up to April, T-bills yields generally hardened at longer maturities, while yields at shorter maturities largely moved in line with the movement of inter-bank rates, QCB said.
Implicit yield on 91-day T-bills generally remained higher than the overnight interbank rate, except in May 2016. It increased from 1.48% in December 2015 to 1.67% in December last year, QCB noted.
