Yen Rises After Record Demand at Japan's 20-Year Bond Auction While the Euro Steadies as French Curfews Take Hold
The yen ended a two-day slide on Tuesday after strong demand for Japanese government debt, and the euro recovered some ground as curfews calmed French streets. The moves were modest, but they show how bond auctions and politics are steering currencies this week.

The moves
The yen rose 0.2% to about 158.15 per dollar on Tuesday, snapping a two-day slide, Reuters reported. The euro gained 0.2% to about $1.1234. Sterling rose 0.4% to about $1.3351. The offshore yuan firmed 0.1% to about 6.678 per dollar after China's central bank left its benchmark lending rates unchanged. Chart 1 sets out the moves. These are European-morning quotes reported by Reuters and will have moved since.
Why a bond auction moves the yen
Japan's 20-year government bond auction drew record demand, with a bid-to-cover ratio of 5.84 against 4.01 last month. Strong demand can ease worries that the market is struggling to absorb government debt supply. It can also shape expectations about how far the Bank of Japan will let yields rise. Traders often read both channels into the currency. The link is plausible, but a single session's move does not prove a causal chain.
The yen's weak starting point
Even after Tuesday's gain, the yen remains near 158 per dollar, a weak level by historical standards. The gap between Japanese and US interest rates continues to favour the dollar. A one-day rebound after an auction does not change that underlying pressure. It does show that the currency responds quickly to signs of stability in Japanese bonds.
The euro and French politics
The euro's recovery followed a difficult Monday. French borrowing costs jumped after violent protests, and the euro slipped. On Tuesday, overnight curfews in Paris and other cities appeared to calm the streets, Reuters reported. The currency recovered part of Monday's loss. The euro is reacting to French risk because France is the euro area's second-largest economy and a large issuer of debt.
Sterling's firmer tone
Sterling's 0.4% rise made it one of the stronger major currencies on the morning. British markets were also dealing with a Google Cloud outage that disrupted several banks, but there was no sign in the reported moves that the outage affected the currency. Domestic economic data and expectations for the Bank of England remain the main drivers.
The yuan after the rate decision
The offshore yuan firmed slightly after the People's Bank of China held its one-year and five-year loan prime rates at 3.00% and 3.50%. A hold was widely expected. Markets were also digesting Governor Pan Gongsheng's comments that the bank will study making the overnight reverse repo rate its main policy rate.
The dollar's backdrop
The dollar index had risen 0.1% to about 101.97 on Monday, according to Standard Chartered's daily note. Oil above $110 a barrel and expectations that the Federal Reserve will hold rates at its 27 to 28 October meeting give the dollar support. Currency moves on Tuesday were small relative to the dollar's broader strength this year.
What to watch
The key events are further Japanese debt auctions, the evolution of French protests and the Fed meeting next week. Quotes move quickly in this environment, and the Journal states observation times with each level.
