Abu Dhabi: US Treasury Secretary Henry Paulson said on Sunday leaders of Gulf oil producing states had told him that abandoning their currency pegs to the dollar will not solve their inflation problems.

Paulson, two-thirds of the way through a four-day trip to Saudi Arabia, Qatar and the UAE, said leaders in the region have "quite an awareness that the peg does not influence inflation to a significant degree.

"They recognise that inflation is the overriding issue ... Ending the peg is not the solution to the inflation problem."

However Paulson said he could not rule out any moves by Gulf states to abandon the peg, reiterating his view that currency policy decisions were sovereign matters.

Five of the six Gulf oil producers - except for Kuwait - peg their currencies to the dollar, which means that they must match US Federal Reserve interest rate cuts even as their economies surge on record high oil prices.

Some in the region argue that this and the dollar's decline in recent months is fuelling inflation, which might be better controlled by pegging to a basket of currencies.

An economic adviser to Qatar's ruler has said the Gulf state needs to drop its peg to the dollar because its economy is surging while the US economy is slowing, London-based MEED reported.

At 13.74 per cent, Qatar's inflation was the highest recorded among Arab countries in the Gulf last year.

But Paulson, in talks with officials including Saudi Arabia's King Abdullah, Qatar's prime minister and finance ministers from the two states, said earlier in Doha he has yet to hear a leader blame the peg as the chief cause of inflation.

Instead, Paulson said, officials in the region cited high prices for food, construction materials such as cement and other key commodities were the primary sources of inflation.

He said they cited Kuwait as a country which is still struggling with high inflation despite its abandonment of a dollar peg last year.

Oil producers in the Gulf region have a long term goal to achieve monetary union and more countries abandoning dollar pegs could hamper those efforts.

Paulson also repeated his view that a strong dollar was in the United States' interest and that the greenback's value would ultimately reflect strong longer-term economic fundamentals.

Paulson also said he believed rapidly growing sovereign wealth funds were mainly seeking returns on their investment rather than pursuing political goals on behalf of their governments.

But he said adoption of "best practice" guidelines by the government-run funds would help allay protectionist fears.

"We're not picking on wealth funds", Paulson said, noting best practices under development by the International Monetary Fund were "a good way to inoculate ourselves against protectionist sentiment around the world".
