The United Stated, United Kingdom and Chinese economies are showing fresh signs of weakening, the Organisation for Economic Co-operation and Development (OECD) said on Wednesday.

According to OECD, the reverse is the case in the euro zone as activity of many countries in the zone is firming up.

The OECD’s monthly leading indicator, a measure designed to flag turning points in the international economy, showed dips for the US, the UK and other key economies such as China and Brazil in May.

The indicator, a synthetic index where 100 is the long-term average, fell to 99.5 in the US from 99.6 in April.

The index remained at 100.7 in the euro zone for the third consecutive month, but eased to 99.8 from April’s 100.0 in the UK.

China’s reading declined to 97.3 from 97.5 and Brazil’s to 98.8 from 99.1.

The index was stable in Japan at 99.9.

Within the euro zone, the index also held steady at 100.7 in France and at 101.0 in Italy, while for Germany, it rose to 100.0 from 99.9.
