LONDON (Reuters) - The euro and Italian government bonds continued on Tuesday to cheer German- and French-led plans for a 500 billion euro EU coronavirus recovery fund, though stock markets were suffering from fatigue after their best day in months.
There was still a sense of optimism after Monday's news that early-stage tests on a possible COVID-19 vaccine had also proved encouraging but the momentum was shifting.
Europe's STOXX 600 index gave up an early rise to slip 0.4% after surging 4% in the previous session, oil began to tread water [O/R] and safe-haven U.S. government bonds were making ground in debt markets.
"The Franco-German proposals are ambitious, targeted and, of course, welcome," European Central Bank President Christine Lagarde said of Monday's plan, which would move the EU in the direction of a so-called 'transfer union'.
The euro was buying $1.0932, having gained about 1% against the dollar since the plan was announced. It was also up near a two-month high against the Swiss franc, while the cost of betting against the euro was falling.
After a sizeable fall in Italian borrowing costs, Spanish and Portuguese yields led the moves lower on Tuesday. Morgan Stanley (NYSE:MS)'s economists called the Franco-German proposal a "powerful common response, helping to mitigate the risk of a southern slump."
The Spanish 10-year yield fell 9 basis points to 0.715%, the lowest since early April, while Portuguese bond yields hit their lowest since March 31, down 12 bps on the day at 0.78%.
Italian yields were between 2 and 8 bps lower on the day. The 10-year government bond yield fell nearly 10 basis points to 1.602%, its lowest since April 9 at one point.
"It was a meaningful breakthrough but it is not going to be plain sailing from here," said Vasileios Gkionakis, Global Head of FX Strategy at Lombard Odier, citing resistance already voiced by a sizeable number of northern EU countries.
In the equity markets, Wall Street's S&P 500 futures were down 0.4% after Monday's strong rally.
Asia had followed. MSCI (NYSE:MSCI)'s broadest index of Asia-Pacific shares outside Japan jumped 1.8% to two-week highs and Japan's Nikkei had added nearly 2%.
In the commodity markets, profit-taking pruned Brent's early gains, though the rally looked broadly intact amid signs that producers are cutting output just as demand picks up.
Brent last stood 0.5% higher at $35 a barrel, after touching its highest since April 9. U.S. WTI was at $32.50. Gold was little changed at $1,731 an ounce.
