French far-right leader Marine Le Pen on Tuesday proposed a more radical fiscal plan, pledging to cut €140 billion in spending over a five-year term if elected president, and planning to enshrine deficit reduction targets in the constitution through a national referendum. Economists have expressed doubts about the feasibility of the plan. Meanwhile, Reuters reported on Wednesday that Angel Ubide, head of fixed income and macroeconomic research at Citadel, warned that France's fiscal policy has little room for error, and that systemic problems in its large economy could escalate into a problem for all of Europe. The market has already reflected these concerns, with France's 10-year government bond yield briefly surpassing 5% last week, reaching a 24-year high, and the euro falling below 1.12 against the dollar, touching a 17-month low.
