THE sharemarket closed slightly lower yesterday as fears that Spain might need another financial bailout overshadowed weaker domestic inflation figures.
The S&P/ASX 200 Index fell 9.3 points, or 0.23 per cent, to 4123.9.
CMC Markets chief market analyst Ric Spooner said investors were worried that a surge in Spain's borrowing costs above 7 per cent would be unaffordable for the debt-laden country if they stayed at that level for long.
"The bottom line is it's very difficult to aggressively reposition yourself into risk assets and equities while Spanish bond rates are where they are," he said. "The Spanish government is now being obliged to pay a borrowing cost that it won't be able to sustain over the medium term."
The release of lower than expected inflation figures did little to encourage investors.
