Slashed cash rate buoys sharemarket

The sharemarket closed the week near a five-year high after the Reserve Bank cut the cash rate to historic lows, and a weakening dollar gave the big miners a boost.

A slight decline in the US unemployment rate also contributed to the buoyant mood, as the dollar fell to an 11-month low of 100.47 US cents early on Friday.

For the week, the benchmark S&P/ASX 200 rose 76.6 points, or 1.5 per cent, at 5206.1 points, while the broader All Ordinaries Index jumped 85.7 points, or 1.7 per cent, at 5191.1 points.

The RBA surprised some economists this week when it cut the cash rate by 25 basis points to 2.75 per cent.

It is the lowest the cash rate has been in decades, as the central bank tries to help rejuvenate non-mining parts of the economy.

The RBA's statement on monetary policy, released on Friday, cut its inflation forecast by three-quarters of a percentage point to 2.25 per cent for the year to June.

"There was very little guidance on the future direction of rates," St George economist Janu Chan said.

"However, the language used suggests a shift to a more neutral stance. Additionally, the few changes to the RBA's assessment on the global and domestic economy suggest that it is not poised to cut rates again immediately."

On Friday, banking stocks finished in negative territory despite the bourse closing at the highest point since June 2008.
