NEW YORK (MarketWatch) -- Yields on Germany's 2-year debt DE:2YR_GER -14.06% fell to 0.10% on Tuesday, their lowest level on a closing basis in at least 10 years, according to FactSet Research. German debt is considered a safe haven during times of market turmoil or worries about the economic outlook. The yield on Germany's short-term security also fell under yields on Japanese 2-year debt, which traded at 0.11%, for the first time since at least late 2010. Japan's yields have been the lowest among major global economies because of the country's "Lost Decade" - or really about two decades.
