LONDON, Sept 26 (Reuters) - Europe's benchmark bond yield steadied on Tuesday after its biggest daily drop in seven weeks as investors waited for a Federal Reserve speech that may flesh out plans to tighten U.S. monetary conditions.
The yield on Germany's 10-year bond, seen as a safe store of cash in times of stress, slid six basis points on Monday after an unexpectedly weak election result for Angela Merkel and after North Korea accused the United States of declaring war.
When European trading began on Tuesday, Germany's yield edged up slightly as analysts said a speech from Fed chair Janet Yellen due at 1645 GMT swept into focus.
Investors will be parsing her words, and those of other Fed officials due to speak on Tuesday, for clues on whether the U.S. central bank will stick to plans to raise interest rates in December.
"Investors are not fully up to speed with the risk of hawkish signals from Fed officials," Mizuho strategist Antoine Bouvet said.
"The Fed is back in a situation where it would want to show optimism at the very least, and the market should be pricing in more hikes in the coming months and quarters than it is currently."
According to CME's FedWatch tool, money markets point to a 70 percent chance of a hike in December but only a 20 percent chance of a further hike in March 2018.
Analysts said a rise in oil to a 26-month high, which bolsters inflation, and a sale of two-year German debt also kept upward pressure on yields.
Yet again, the market's reaction to the latest escalation in tension between North Korea and the U.S. proved short-lived.
Yields on U.S. Treasuries and German Bunds fell to a day's low when North Korean Foreign Minister Ri Yong Ho said on Monday afternoon that Twitter comments from U.S President Donald Trump amounted to a declaration of war.
Both traded back up early on Tuesday in what analysts say reflects a widespread belief that diplomacy will still prevail.
At 1020 GMT, German 10-year yields rose 1 basis point to 0.40 percent, just off an 11-day low of 0.395 percent hit on Monday.
All other euro zone bond yields were a touch higher on Tuesday.
Elsewhere, Emmanuel Macron will push on with plans to detail a major overhaul of the single currency zone, even though a weakened Merkel may not be in a position to help him deliver on it.
Her conservatives were already resistant to some aspects of the French President's plan, notably an idea to give the euro zone a multi-billion-euro budget of its own, administered by Brussels. Her likely new coalition partners, the FDP, are even more hostile to that.
