Every U.S. Treasury maturity except the two-year closed above 5% on Wednesday, after a weak $70 billion five-year auction sent the 10-year yield to 5.13%, its highest since 2007. Stocks fell as traders priced in another Fed hike in October.

PARA 01
The losses in the United States Treasuries market1intensified on Wednesdayas robust economic data and a weak auctiondroveyields across most maturitiesto the highest levels in almost two decades.
Higher oil pricessparked the declines earlier in the session,fanning worries around elevated inflation and punishing European government debt as well.Releases showing stronger-than-forecast U.S. manufacturing and services activityaccelerated the slide,which then picked up speed as a five-year Treasury auction drew surprisingly dim demand.6
The auction resultspushed the yield on five-year U.S. notes2above five per centfor the first time since 2007, leaving the two- and three-year maturities the only coupon-bearing tenors below that milestone level.Thirty-year yields surged closer to their highest since 2004.The selloff spilled over into stocks, with the S&P 500 Index dropping almost one per cent at one point.

“You don’t want to step in front of the freight train today,”said Sean Simko, head of fixed-income investment management at SEI Investments.“You’re seeing the trifecta —stronger economic data, supply pushing the five-year to levels we haven’t seen in yearsand the view that inflation is sticky globally.”
“今天你可不想站到那辆疾驰的火车前面，”SEI Investments 固定收益投资管理主管 Sean Simko 说。“你看到的是三件事凑到了一起 ——更强的经济数据、把五年期收益率推向多年未见水平的供给以及全球通胀具有粘性的看法。”
PARA 05
The economic data and the jump in oil prices amid the standoff in the Middle Eastled traders to boost bets on further Federal Reserve policy tightening.Officialslifted borrowing costs last week for the first time in three years, to a range of 3.75 per cent to four per cent,a move Chairman Kevin Warsh said removed a “dose of accommodation.”
经济数据，加上中东僵局之下的油价跳涨，促使交易员加大对美联储进一步收紧政策的押注。官员们上周三年来首次提高借贷成本，把目标利率区间上调到 3.75%–4%，美联储主席 Kevin Warsh 称，这一步去掉了“一剂宽松”。

Swaps8now fully reflectthree quarter-point hikes over the next year,with significant hedging for a fourth increase.If realized, that would take the central bank’s target rate into a range of 4.75 per cent to five per cent.

“Pressure is starting to build up on the short end of the yield curve,”5said Christophe Boucher, CIO of ABN AMRO Investment Solutions.Wednesday’s economic datawill allow the Fed to “double down” on its hawkish stance, he said.7
The 5.033 per cent yield required to clear the auctionwas more than three basis points above3the expected level ahead of the bidding deadline.By that measureit was the second-worst five-year auction in data recorded since 2018, exceeded only by the result in June 2022 after the first of the Fed’s several jumbo 75 basis point rate hikes.
The rate on the maturity4surged as much as 20 basis points on Wednesday.The yieldsurpassed the high of 4.99 per cent seen in 2023,at the peak of the Fed’s hiking cycle to tame surging inflation.
Meanwhile,the benchmark 10-year raterose almost 17 basis points to 5.13 per cent, the highest since 2007.The 30-year yieldtraded at about 5.4 per cent, the highest since 2007,and within about 4 basis points of the highest level since 2004.

PARA 13
Policymakershave become increasingly worried aboutinflation that hasn’t retreated to their two per cent target in five and a half years,with some warning of price pressures that appear to be persistent as international tensions keep energy prices elevated.That’s against the backdrop of a robust U.S. labour market.
The bond selloffraises the stakes forthe Treasury Department’s expanded buyback program,9announced in mid-August after long-term yields climbed to multiyear highs that have since been exceeded.The second operation under the expansion,targeting debt maturing in 20 to 30 years, is set for Thursday.

PARA 15
Benchmark 20- and 30-year yieldsadded to their climbafter the announcement that the buyback target— which officials previously had said would at least double to US$4 billion —would be US$6 billion, the same as the first expanded operation on Sept. 10.
A Treasury is a bond the U.S. government sells to borrow money. You hand Washington cash today; it pays you interest and returns your money on a fixed date.
Why it matters here ▸ The whole article is about the price of this one instrument. When Treasury prices fall, their yields rise — and that sets the borrowing cost for mortgages, companies and the government itself.
Extended note: Treasuries are called risk-free because the U.S. government can tax and print. Every other borrower pays a spread on top of the Treasury yield.
2yield/jiːld/点击看中文解释 ↓
The yield is the yearly return you get if you buy a bond at today's price and hold it until it is repaid. It is written as a percentage.
Why it matters here ▸ “The benchmark 10-year rate rose almost 17 basis points to 5.13 per cent” is the number the whole story hangs on: a higher yield means costlier money for everyone.
Extended note: Yields are set by the market, not by decree: they are the price at which buyers and sellers agree to lend. The 10-year is the global benchmark for 'risk-free' money.
3basis point/ˈbeɪsɪs pɔɪnt/点击看中文解释 ↓
A basis point (bp) is one hundredth of a percentage point: 0.01%. So 100 basis points = 1 percentage point.
Why it matters here ▸ “The rate on the maturity surged as much as 20 basis points” = it jumped 0.20 percentage points in a single day. For a 30-year bond that is a violent move.
Extended note: Central banks usually move in 25bp steps, so 'three quarter-point hikes' means 75bp in total — exactly what swaps now price for the next year.
4maturity/məˈtjʊərəti/点击看中文解释 ↓
The maturity of a bond is the date it is repaid, and by extension the length of the loan: a 2-year, 5-year, 10-year or 30-year.
Why it matters here ▸ The article compares maturities one by one — 5-year, then 10-year, then 30-year — because 'the bond market' is really a ladder of loans of different lengths.
Extended note: Short maturities track central-bank policy; long maturities track inflation and deficit expectations. Reading which end moved tells you what the market is actually worried about.
5yield curve/jiːld kɜːv/点击看中文解释 ↓
The yield curve is one line that plots the yields of the same borrower across all maturities, from a few months out to 30 years.
Why it matters here ▸ “Pressure is starting to build up on the short end of the yield curve” — the short end is the 2- to 5-year zone, the part most sensitive to Fed policy. That is exactly where Wednesday's damage was worst.
Extended note: A curve that shifts up everywhere is a re-tightening signal; a curve that flips to downward-sloping (inverted) is an early recession alarm.
6auction/ˈɔːkʃn/点击看中文解释 ↓
An auction is how the U.S. Treasury sells new debt. Dealers and investors bid, and the price that clears the whole amount — the lowest yield the market will accept — wins.
Why it matters here ▸ “The 5.033 per cent yield required to clear the auction was more than three basis points above the expected level” — buyers demanded extra compensation, and that shortfall of demand is what snapped the five-year past 5%.
Extended note: A 'tail' means the Treasury had to pay more than expected to sell the bonds. Investors are demanding a bigger term premium to hold government debt.
7hawkish/ˈhɔːkɪʃ/点击看中文解释 ↓
A hawkish central banker sounds tough on inflation and leans towards higher interest rates; a dovish one worries more about growth and leans towards cutting.
Why it matters here ▸ “Wednesday's economic data will allow the Fed to 'double down' on its hawkish stance.” In plain terms: strong data gives the Fed a licence to keep raising rates.
Extended note: Watch what the market prices, not just the adjectives: swaps and futures turn every hawkish sentence into a probability within minutes.
8swap/swɒp/点击看中文解释 ↓
An interest-rate swap is a private contract in which two parties trade fixed interest payments for floating ones. Big investors use it to hedge or to bet on where central-bank rates will go.
Why it matters here ▸ “Swaps now fully reflect three quarter-point hikes over the next year” — 'fully reflect' means the market has already put a 100% probability on those moves.
Extended note: Swap-implied rates are a market consensus, not a forecast: they shift every time a data release lands, which is why a single PMI print can reprice the whole curve.
9buyback/ˈbaɪbæk/点击看中文解释 ↓
Here a buyback means the U.S. Treasury using its cash to buy back some of its own older bonds in the market before they mature.
Why it matters here ▸ “The bond selloff raises the stakes for the Treasury Department's expanded buyback program” — with yields at 2007 highs, the government's own attempt to support the long end is now under the spotlight.
Extended note: The size is the message: US$6 billion cannot bend a multi-trillion-dollar market, so investors read it as a signal that the Treasury is worried about long-end borrowing costs.

3 道题。点选项立即判分；解析需要单独点开。
Q1According to the article, what pushed U.S. Treasury yields to their highest levels in almost two decades on Wednesday?
正确答案：B
文章第一段就把原因讲清了：强劲的经济数据加上一场疲软的拍卖，把多数期限的收益率推到近二十年高位。第二段补充了油价走高这一早期推手；第十段用拍卖细节坐实需求疲软（中标利率高于预期、为 2018 年有记录以来第二差）。A 错在时间与事实：加息发生在上周，不是周三，周三只是预期升温。C 把油价方向说反了（原文是 Higher oil prices；布伦特当天还涨了 3.86%），制造业数据也是强于预期而非弱于预期。D 与原文相反：抛售反而让财政部的回购计划更关键，周四就有一场操作。 The losses in the United States Treasuries market intensified on Wednesday as robust economic data and a weak auction drove yields across most maturities to the highest levels in almost two decades.Distractor check: A confuses last week's actual hike with the market's rising odds for October; C reverses the direction of both oil and the PMI; D contradicts the buyback paragraph.
Q2The article says swaps “now fully reflect three quarter-point hikes over the next year.” What does that tell you?
正确答案：B
「掉期市场已完全计入」= 交易员把这些加息写进了价格，属于预期。原文紧接着用虚拟语气划清界限：If realized, that would take the central bank's target rate into a range of 4.75 per cent to five per cent.（“如果真发生，才会……”）。A 错在把「预期 3 次」读成「已经加了 3 次」——事实上这是三年来首次加息周期的开端。C 方向反了：市场押注的是加息而不是降息。D 把市场定价误解为官方承诺；美联储没有在声明里承诺过。 Swaps now fully reflect three quarter-point hikes over the next year, with significant hedging for a fourth increase.Key distinction: market pricing is a probability, official policy is a decision. 'Fully reflect' means 100% priced, and 'would take' signals a hypothetical outcome.
Q3What does the article's closing discussion of the buyback programme suggest about the Treasury's position?
正确答案：A
原文用了 raises the stakes（把事情的分量抬高了）这一判断，并说明该计划是「在长期收益率升至多年高位之后」于 8 月中旬宣布的，而这些高点此后又被刷新 —— 弦外之音正是：收益率涨得太高，财政部坐不住了。而这次操作规模只有 60 亿美元、与 9 月 10 日首次操作持平，也暗示其力度有限、更像表态。B 错在对象与机制：回购针对的是 20–30 年期债务，不是把某个收益率「钉住」。C 把角色搞反了，回购是财政部的债务管理工具，不为助力加息。D 与事实相反，操作就定在周四。 The bond selloff raises the stakes for the Treasury Department's expanded buyback program, announced in mid-August after long-term yields climbed to multiyear highs that have since been exceeded.The phrase 'that have since been exceeded' is the tell: the problem the programme was designed for has got worse, which is why the stakes are higher now.
