ANKARA: World financial leaders will agree to calibrate and communicate monetary policy carefully to avoid triggering capital flight, but will not call an expected US rate rise a risk to growth, a draft communique showed on Friday.

Many emerging market economies are concerned that when the US Federal Reserve raises borrowing costs, investors will withdraw from other markets and buy dollar assets, weakening other currencies and creating turbulence as capital flees.

Officials from emerging markets wanted the communique from finance ministers and central bank governors of the Group of 20 biggest economies, meeting in Turkey, to say that a US rate rise now would be a risk to growth.

But the draft avoids such wording.

"We note that in line with the improving economic outlook, monetary policy tightening is more likely in some advanced economies," the draft communique, seen by Reuters, said.

"We will carefully calibrate and clearly communicate our actions to minimize negative spillovers, mitigate uncertainty and promote transparency," said the draft, which may yet change before it is finally agreed on Saturday.

An earlier version of the text said policy tightening in developed economies "may remain one of the main sources of uncertainty in financial markets".

"In one of the wild formulations it said that this was the biggest threat to the world economy. This was killed immediately and forever," a Russian source said earlier.

The text welcomed strengthening activity in some economies but said that global growth fell short of expectations, although it expressed confidence a recovery would gain speed.

It also indirectly addressed Chinese moves that weakened its yuan currency in August, in a sign these were not seen as a competitive devaluation to prop up Chinese exports. G20 members reiterated their commitment to exchange rate flexibility and would "refrain from competitive devaluations and resist all forms of protectionism," it said.

Reinforcing that message, U.S. Treasury Secretary Jack Lew told Chinese Finance Minister Lou Jiwei that it was important that China let the yuan move up as well as down, and avoid any move to lower its value to gain a competitive edge in global trade, a US official said.

China told the group it was committed to continuing structural reforms and to supporting economic growth, Europe's Economic Commissioner Pierre Moscovici told reporters after the meeting.

Slower growth in China and rising market volatility have boosted the risks to the global economy, the International Monetary Fund warned ahead of the G20 meeting, citing a mix of potential dangers such as depreciating emerging market currencies and tumbling commodity prices.

But the G20 had been seen as unlikely to come up with any concrete new measures to address the spillover from instability in the world's second-largest economy, or to call directly on Beijing to address structural issues such as rising bad debts.

EASY MONEY

Luxembourg Finance Minister Pierre Gramegna, whose country holds the rotating presidency of the European Union, shrugged off the prospect of US interest rate hikes.

"We cannot live all the time on easy money ... One has to be realistic that at one point in time the curve of interest rates will have to change," he told Reuters.

Bank of Japan Governor Haruhiko Kuroda said any Fed rate rise would be a positive sign for the global economy, despite the unease in some emerging markets that such moves could cause capital outflows and currency volatility.

"If the US were to raise rates, that would speak to the underlying firmness and growth in the US economy, and that would actually be a plus for the global economy," he said.

One specific idea being examined at the Ankara meetings is a proposal from a group of financial stability experts to adopt a two-stage approach for introducing Total Loss Absorption Capacity (TLAC) buffers for big banks, a G20 source said.

The buffer is a new layer of debt big banks like Goldman Sachs and Deutsche Bank AG must issue to write down in a crisis and bolster their capital.

The proposal would introduce a buffer of 16 percent of a bank's risk-weighted assets from 2019 and 20 percent from 2022, the source said.

The United States had pushed for 20 percent, while some in Europe had been arguing for 16 percent on the grounds that their banks were still recapitalising after the financial crisis.

The draft pencilled in that a deal should be ready for the endorsement of G20 leaders at their summit in southern Turkey in November, but some countries were concerned there would not be enough time to reach a final agreement by then.

There was no clear pronouncement on China's desire to have the yuan included in the International Monetary Fund's Special Drawing Rights basket of currencies, but the draft said G20 finance chiefs expected progress in November, when the IMF has a board meeting on the issue.

"China has moved in the direction in currency and monetary policy ... that is necessary if they want to achieve the goal of getting China into the IMF currency basket," German Finance Minister Wolfgang Schaeuble told reporters, welcoming Beijing's near 2 percent yuan devaluation last month.

China is keen for the symbolic boost it would get from the yuan's inclusion.

Bundesbank chief Jens Weidmann said he is open to discussion on including the yuan in the IMF basket, and said China's recent market upheavals should not pose a lasting danger to the global economy.

"The currency basket should in principle reflect relative global economic strengths," he told Reuters, but added China must fulfil the conditions for inclusion.

One delegate said it was possible that the likely failure of the US Congress to approve an IMF quota reform that would give China and other emerging markets more say could work in Beijing's favour on the SDR issue.

The reasoning goes that benefiting the leading emerging economy, China, could help offset the perennial failure to boost emerging market quotas.

However, IMF members will also be examining whether China's heavy intervention in the yuan market was befitting of a freely convertible reserve currency, the delegate said.

One option being floated was the idea of giving China a more limited share of the SDR basket at first until its convertibility and market orientation improved.
