London, May 14 (BridgeNews) - U.K. producer output prices posted a non-seasonally adjusted yearly rise of just 0.5% in April, the lowest increase since March 1999, data issued Monday by the Office for National Statistics showed. This modest increase came in spite of an 6.6% unadjusted yearly rise in input prices. The input price increase "mainly reflected a rise in crude oil prices," the ONS said. Crude oil prices rose by 6.3% between March and April and by 22.2% on the year.
* * * On the output side, the impact of budget changes on petroleum and tobacco duty appeared to have little effect, contrary to some analysts expectations.
The ONS said even if the budget duty change on petrol and tobacco had been passed on in full, they would only have reduced the output index by 0.1 percentage points in April.
The effect of foot-and-mouth disease among U.K. livestock did appear to show up on the output side. The output food index rose by 0.2 percentage points between March and April, and the ONS said this was "mainly caused by rises in meat product prices."
