* Yield-curve inversion latest sign of economic trouble
* Yen, Swiss franc benefit from safe-haven flows
* Falling Treasury yields pressure dollar/yen
By Stanley White
TOKYO, Aug 15 (Reuters) - The yen held on to gains against
major currencies in early Asian trading on Thursday as growing
signs of a global economic slump drove investors into safe-haven
assets.
The Swiss franc and gold also edged higher as investors fled
from stocks and sought safe-haven assets after the U.S. Treasury
yield curve inverted for the first time in 12 years and U.S.
stocks sold off sharply.
The inversion, where 2-year yields trade higher than 10-year
yields, is considered by some analysts to be a sign that the
U.S. economy is likely to enter a recession.
Sentiment was already fragile after disappointing economic
data from China and Germany revealed the extent of the damage
the U.S.-Sino trade war is causing to two of the world's most
important exporters.
Safe-haven currencies, gold, bonds and other low-risk assets
could continue to get a boost due to growing worries about the
poor health of the global economy.
"When volatility rises, dollar/yen becomes strongly
correlated with Treasury yields, so the currency pair has more
room to fall," said Junichi Ishikawa, senior foreign exchange
strategist at IG Securities in Tokyo.
"I expect other safe havens to rise. The mood is downbeat,
because of the trade war and bad economic data."
The dollar was a tad lower at 105.85 yen JPY=EBS in Asian
trading Thursday. On Wednesday, the yen rallied 0.8% versus the
greenback, its biggest daily gain in two weeks.
The dollar index .DXY , which measures its value against a
basket of six major currencies, stood at 97.987 after a 0.2%
gain on Wednesday.
The U.S. Treasury yield curve US2US10=TWEB temporarily
inverted on Wednesday for the first time since June 2007. U.S.
30-year yields also plunged, dropping to a record low of 2.015%.
Against the dollar, the Swiss franc CHF=EBS last traded at
0.9766, holding on to a 0.3% gain posted on Wednesday.
Spot gold XAU= , which is usually bought in times of
economic uncertainty, traded near the highest in six years.
