PRAGUE, Dec 16 (Reuters) - The Czech central bank surprised markets on Wednesday with a 25 basis point cut in its main interest rate to a new record low, showing the bank's concern of protracted economic weakness.
Policymakers trimmed the main two-week repo rate <CZCBIR=ECI> <CZRP=>, used to skim off excess liquidity, to 1.00 percent, bringing it in line with the euro zone's main rate and far below rates in other non-euro central European countries.
The crown <EURCZK=> weakened as much as 0.7 percent to 26.275 per euro following the decision but later firmed back to around 26.225, slightly above Tuesday's closing levels. Money market rates dropped.
Analysts had said the decision would be a close call and the market had priced in a 25-50 percent chance of a cut, but most banks had forecast no change due to losses of 0.6 percent for the crown in the last month and a pick-up in inflation.
"Today's decision is a bit surprising when seen in the context of recently released data and growing risk aversion in financial markets," said Radomir Jac, chief analyst with Generali PPF Asset Management.
"Risk aversion and the possibility of a weaker crown were the key reasons for keeping interest rates on hold in November."
Analysts and dealers pointed to board member Eva Zamrazilova, who voted for stable rates in November, as the voter most likely to have swung the balance on the seven strong board.
She said last week she saw room for a cut if there were no inflation pressures on the horizon [
].Most economists said the move was probably the last cut in the present easing cycle and months of stability were now most likely.
The bank also cut the Lombard rate, used for overnight lending to banks, by 25 basis points to 2.0 percent. But it left the discount rate paid to banks for overnight deposits unchanged at 0.25 pct, breaking the custom of moving all rates simultaneously.
Money market rates <CZKF=> fell, with one week interbank rates <CZKSWD=> down to 0.85/1.18 at 1149 GMT from 1.05/1.35 before the decision. Forward Rate Agreements <CZK3X6F=>, contracts betting on future changes in interest rates, eased to 1.52/1.57 from 1.62/1.67, according to Reuters data.
CROWN IN SPOTLIGHT
Dealers said the cut boosted the likelihood that the crown would be used as a funding currency of carry trades, which use currencies with low interest rates to invest in higher yielding ones.
"The crown has the lowest rates in the region and in the case of a negative outlook for the region all currencies in the region would weaken in the same way," said David Navratil, an analyst at Ceska Sporitelna.
Analysts believe the highly open Czech economy has probably passed the worst but they do not expect any strong upturn and there are substantial political and budget risks ahead of an election next year.
The economy shrank at 4.1 percent in the third quarter, less than the bank forecast for a 4.9 percent contraction. It grew 0.8 percent on quarterly basis.
But a shrinking household consumption and worsening labour market threatening to suppress demand and subsequently price growth, justified views of the need for more easing.
Consumer inflation was 0.5 percent in November, above the bank's forecast for 0.1 percent. The bank targets consumer inflation at 2 percent with a tolerance band of 1 percentage point either side.
