LONDON, June 17 (Reuters) - Share markets couldn't add to recent gains and government bond yields inched fractionally higher on Monday, as investors hunkered down for what is shaping up to be a crucial week for global monetary policy.
With expectations running high that the U.S. Federal Reserve will signal on Wednesday its first rate cut since the financial crisis, only a few asset classes were straying far.
The focus was still the dollar's surge late last week after above-forecast U.S. industrial output and retail sales data and upbeat consumer confidence soundings pushed back futures markets bets of any quick Fed chop.
The greenback held its gains as most major currencies trod water. Wall Street futures looked flat too, while a 10% drop in German airline Lufthansa's shares following a profit warning kept Europe's STOXX 600 subdued.
"A (U.S.) rate cut this week seems extremely premature," said Royal Bank of Canada Capital Market's Global Head of FX Strategy Elsa Lignos.
"But the Fed can make some communications tweaks that at least open up the possibility for a cut in July. The question is how flexible that messaging will be."
Traders are pricing a high probability of a July rate cut, despite there being unusually high uncertainty, particularly around trade, Lignos added. She said a G20 meeting late this month could also change the narrative again.
The main concern, though, is if tensions do continue, the trade war could tip the U.S. and other economies into recession.
European Central Bank board member Benoit Coeure said in an interview that the bank's sub-zero interest rates could be cut again if needed. It could also restart the quantitative easing programme it wound down at the end of last year.
It came too as long-term euro zone inflation expectations hit a new all-time low. Euro zone bond yields did inch fractionally higher as had U.S. Treasuries, though to all intents and purposes they were still in multi-year troughs.
The dollar's index against a basket of six major currencies , meanwhile, brushed a two-week high of 97.603 as the yen drifted and the euro fetched $1.1216, near the lower end of its recent trading range.
"The question is not whether we have instruments; we do have instruments. We can change our guidance. We can cut rates. We can restart QE," Coeure told the Financial Times.
"The question is which instrument, or combination of instruments, would be best suited to the circumstances."
In emerging markets, average sovereign yields were at 6-year lows and a welcome drop in unemployment helped Turkey's markets brush off another sovereign downgrade from Moody's and a warning risks of a full-blown crisis were rising.
MSCI's broadest index of Asia-Pacific shares outside Japan had ended slightly weaker overnight while Japan's Nikkei average had closed flat.
The Bank of Japan also meets this week and is widely expected to reinforce its commitment to its massive stimulus programme.
There had been something of boost from Hong Kong's Hang Seng Index which finished 0.4% higher. At the weekend, the territory's leader Carrie Lam backed down over a bill that would have allowed extradition to China.
The Hang Seng had fallen for three sessions in a row, after the extradition bill triggered mass protests and some of the worst unrest seen in the territory since Britain handed it back to Chinese rule in 1997.
"Last week the issue looked as if it would become another thorny point between the United States and China. As the bill is now being postponed indefinitely, things will likely calm down, which is good for markets," said Hiroyuki Ueno, senior strategist at Sumitomo Mitsui Trust Asset Management.
Mainland Chinese shares traded within a tight range, with the benchmark Shanghai Composite up 0.2% and the blue-chip CSI 300 barely budging.
U.S. Secretary of State Mike Pompeo told Fox News on Sunday that President Donald Trump would raise the issue of Hong Kong's human rights with China's President Xi Jinping at a potential meeting of the two leaders at the G20 summit in Japan this month.
Bitcoin jumped overnight to $9,391.85, its highest level in 13 months. It was last quoted at $9,195.62, up 2.4%.
Geopolitical tensions in the Middle East added another layer of uncertainty after the United States blamed Iran for attacks on two oil tankers in the Gulf of Oman last week.
Pompeo had also said Washington will take all actions necessary to guarantee safe navigation in the Middle East, though oil prices slipped again as worries about the broader slowdown in the global economy dominated.
Brent futures fell 65 cents, or 1%, to $61.36 a barrel after gaining 1.1% on Friday. U.S. West Texas Intermediate (WTI) crude futures were down a similar amount at $51.95, having firmed by 0.4% in the previous session.
Also sapping prices was the dim outlook for oil demand growth in 2019 projected by the International Energy Agency (IEA) on Friday, citing worsening prospects for global trade.
