Asian stocks skid on Ukraine fears, oil at 7-year peak

Asian shares sagged on Monday as warnings that Russia could invade Ukraine at any time sent oil prices to seven-year peaks, boosted bonds and belted the euro.

The United States on Sunday said Russia might create a surprise pretext for an attack, as it reaffirmed a pledge to defend "every inch" of NATO territory.

The cautious mood saw MSCI's broadest index of Asia-Pacific shares outside Japan drop 1.2%. Japan's Nikkei lost 2.6%, while Chinese blue chips fell 0.6%.

S&P 500 futures were down a fraction and Nasdaq futures eased 0.1% after steep losses on Friday. EUROSTOXX 50 futures shed 1.8% and FTSE futures 0.7%.

Markets have been in convulsions since an alarmingly high US inflation reading sparked speculation the Federal Reserve might raise rates by a full 50 basis points in March.

There was even chatter about an emergency inter-meeting hike. That was spurred in part by the timing of a closed Fed Board meeting for Monday, though the event seemed routine.

The talk was tamped down when the Fed released an unchanged bond buying schedule for the coming month, since the central bank has said it would only hike after its buying had ceased.

San Francisco Fed President Mary Daly also played down the need for a half-point move in an interview on Sunday, saying being too "abrupt and aggressive" on policy could be counter-productive.

Futures markets since have scaled back the risk of a half-point rise to around 40%, when it had been priced as a near certainty at one stage last week.

"Broad-based inflation pressures have given rise to earlier-than-expected pressure for a synchronised shift toward restrictive policy across the globe," said JPMorgan chief economist Bruce Kasman.

"But we do not expect it to translate into aggressive action in March," he added. "In part, this reflects uncertainties related to Omicron, geopolitical tensions, and the purchasing power squeeze from high inflation—all of which weigh heavily on current-quarter growth."

Attention will now be on an appearance by St. Louis Fed President James Bullard later on Monday, given he recently called for 100 basis points of tightening by June.

All the rate chatter sent Treasury yields to peaks last seen in 2019, before geopolitical tensions prompted a safe-haven rally late on Friday. Yields on 10-year notes were last at 1.94%, having been as high as 2.06% last week.

The yield curve also flattened markedly and almost inverted between seven and 10-year maturities, as investors wagered the coming Fed tightening would slow economic growth.

The risk of war in Ukraine has seen the euro retreat to $1.1344, from last week's top of $1.1495. The safe-haven yen regained some ground to leave the dollar at 115.37 yen, from a peak of 116.33.

The Bank of Japan conducted an unlimited bond buying offer on Monday to restrain yields there.

The drop in the euro lifted the dollar index up to 96.059 and away from last week's trough of 95.172. The dollar was also up at 77.15 roubles, after jumping 2.9% on Friday.

Gold was holding gains at $1,859 an ounce, after climbing 1.6% on Friday.

Oil prices climbed further to fresh seven-year highs amid concerns a Russian invasion of Ukraine would trigger US and European sanctions and disrupt exports from the major oil producer in an already tight market.

Brent added another $1.14 to $95.58 a barrel, while US crude rose $1.34 to $94.44.
