* Nigeria leads OPEC output fall in May from multi-year high

* IEA report due on Tuesday

LONDON, June 13 (Reuters) - OPEC forecast that the world oil market will be more balanced in the second half of 2016 as outages in Nigeria and Canada help to speed up the erosion of a supply glut.
The Organization of the Petroleum Exporting Countries said its oil output fell 100,000 barrels per day (bpd) to 32.36 million bpd in May, according to its monthly report. That is 160,000 bpd less than OPEC’s forecast of the average demand for its crude in the second half.
Oil has risen to $50 a barrel from a 12-year low of $27 in January as the outages curb excess supply. These, say OPEC, are accelerating a tightening in the market it expected to happen anyway, as lower prices finally take their toll on higher-cost supply outside the group.
“The excess supply in the market is likely to ease over the coming quarters,” OPEC said in the report, published on Monday.
“Shutdowns in Nigeria and Canada tightened the oil market markedly and brought supply and demand more closely into alignment earlier than many had expected, bolstering prices.”
But OPEC cautioned: “Nevertheless, there is still a massive global supply overhang.”
Prices collapsed from $100 two years ago in a drop that deepened after OPEC refused to cut output, hoping lower prices would curb rival supply. With signs the strategy is working, OPEC at a June 2 meeting made no change to its output policy.
The price drop is hitting non-OPEC supply as companies have delayed or cancelled projects around the world. OPEC forecasts supply from outside producers will decline by 740,000 bpd in 2016 led by the United States, unchanged from last month.
OPEC supply had been climbing since the 2014 policy shift, reaching its highest since 2008 in April. The output drop in May was led by Nigeria, the report said citing secondary sources.
With demand for OPEC crude expected to rise to an average of 32.52 million bpd in the second half as non-OPEC supply falls and seasonal demand rises, OPEC’s report points to a deficit of 160,000 bpd if the group keeps pumping at May’s rate.
OPEC said its output exceeded the demand for its crude by 2.59 million bpd in the first quarter, when prices hit the 12-year low.
OPEC stuck with a forecast that world oil demand will rise by 1.20 million bpd this year.
The next closely watched report on global oil supply and demand is due on Tuesday from the International Energy Agency. (Reporting by Alex Lawler; editing by Jason Neely/Ruth Pitchford)
