Growth and credit data released today in China brought mixed news. First-quarter headline gross domestic product registered an annualized 6.7 percent growth, in line with both consensus forecasts and Beijing’s guidance and a sign that China’s economy has stabilized. Separately, credit data from the People’s Bank of China for March was much stronger than forecast, with new loans rising sharply. The continued credit expansion coupled with strength in the fixed-investment segment of GDP raises concerns that the ongoing rebound is being heavily fueled by debt and central-bank liquidity measures. The question facing investors is whether the current pace of growth is sustainable without these massive credit flows.

Citi beats estimates. First-quarter results issued today by Citigroup included profits that were higher than consensus analyst estimates at $1.10 per share versus $1.51 for the same period a year earlier. Returns were driven in part by a drop in operating costs, which fell to $10.5 billion after streamlining and headcount reduction measures instituted by CEO Mike Corbat. First-quarter trading revenues for both equities and fixed income contracted for the fourth consecutive year to less than $4 billion.
