Australia’s business mood improved in July even as operating conditions softened, according to the National Australia Bank’s monthly survey released Tuesday. The headline Business Confidence Index rose to 7 from 5 in June, marking its highest reading since earlier this year and suggesting that firms are becoming more optimistic about the economic outlook. By contrast, the survey’s Business Conditions Index slipped to 5 from 9, indicating a moderation in trading, profitability and employment metrics. Economists monitor the twin measures for clues on corporate investment and hiring plans; the divergence signals that while sentiment is recovering, firms are still experiencing uneven demand on the ground.
