Barclays Capital warns in the 56th edition of its annual research publication, the Barclays Equity Gilt Study 2011, which was published last week in London, that the current focus of policymakers on short-term results suggests that markets and economies are likely to continue to exhibit a high degree of volatility, reminiscent more of the 1970s and 2000s than the 1980s or 1990s.  The recent impact of rapid commodity price rises on inflation is covered in the study, which makes the case that the disinflationary impact of low cost producers such as China and India is transitioning into an inflationary influence. As a result, the global disinflationary trend of the past 30 or so years appears to be turning.
