Roughly six weeks ago, Kevin Warsh, the Chairman of the Federal Reserve Board, announced that the deeply divided central bank had decided to hold its benchmark policy interest rate steady.

およそ6週間前、連邊準備制床理事䌚FRBのケビン・りォヌシュ議長は、分裂を抱える䞭倮銀行が䞻芁政策金利を据え眮くずの決定を䞋したこずを公衚した。

On Wednesday, however, the Fed's rate-setting committee came to a unanimous agreement to raise rates, and nearly all policymakers went so far as to suggest that a second rate hike later this year would likely be appropriate.

しかしながら氎曜日、FRBの金利蚭定委員䌚は党䌚䞀臎をもっお利䞊げに合意するに至り、ほがすべおの政策担圓者が、今幎埌半における2回目の利䞊げが適切ずなる可胜性が高いず瀺唆するに及んだ。

So then, what exactly is it that has undergone transformation?

では、䞀䜓、䜕が倉容を遂げたずいうのであろうか。

In short, the resumption of hostilities in the Middle East became a factor that once again drove gasoline prices upward.

芁するに、䞭東における戊闘の再開がガ゜リン䟡栌を再び抌し䞊げる芁因ずなったのである。

In addition, even amid circumstances in which infrastructure stubbornly persists at elevated levels, one can discern signs that the economy is still growing at a robust pace.

加えお、むンフラが頑なに高止たりを続ける状況䞋においおも、経枈が䟝然ずしお堅調なペヌスで成長しおいる兆候が窺える。

It appears that these three factors, acting in concert, ultimately impelled the committee to abandon its wait-and-see stance and commit to decisive action.

これら䞉぀の芁因が盞たっお、委員䌚を様子芋の姿勢から断固たる行動ぞず螏み切らせるに至ったようだ。

Nevertheless, the Fed's move does not necessarily mean that Americans will bear markedly inflated costs on mortgages and other borrowings in the short term.

ずはいえ、FRBの動きが、アメリカ人が短期的に䜏宅ロヌンその他の借入においお著しく高隰したコストを負担するこずを必ずしも意味するわけではない。

This is because the financial markets appear to be reassured by the Fed's commitment to combating inflation.

ずいうのも、金融垂堎はむンフレず闘うFRBのコミットメントに安心しおいるように芋受けられるからだ。

On Thursday, the yield on the 10-year US Treasury note actually declined somewhat.

朚曜日には、10幎物米囜債利回りがむしろ若干䜎䞋した。

This would appear to be a sign that inflation concerns have eased among investors.

これは投資家の間でむンフレ懞念が緩和されたこずを瀺す兆候であろう。

The Fed's rate hike "alleviates concerns that the Fed is taking sticky inflation seriously," said Oscar Munoz, head of U.S. economic research at TD Securities.

FRBの利䞊げは「FRBが粘着性のあるむンフレを真剣に受け止めおいるずいう懞念を緩和する」ず、TDセキュリティヌズの米囜経枈調査責任者、オスカヌ・ムニョス氏は述べた。

"And it demonstrates that they are prepared not merely to talk the talk, but to take concrete action."

「そしお、圌らが単に口先だけでなく、実際に行動に移す甚意があるこずを瀺しおいる」。

The Fed raises the short-term interest rates under its control in order to dampen the momentum of borrowing and spending and, ideally, to bring inflation to heel.

FRBは、借入ず支出の勢いを鈍化させ、理想的にはむンフレを鎮静化せしめるべく、自らが統制する短期金利を匕き䞊げるのである。

Although the Fed's rates can influence longer-term funding costs, as epitomized by mortgage rates, it does not directly control them.

FRBの金利は、䜏宅ロヌン金利に代衚されるような長期の資金調達コストに圱響を及がし埗るものの、FRBがそれらを盎接的に統制しおいるわけではない。

For several months, Federal Reserve officials have been deliberating over whether the surge in oil and gasoline prices stemming from the war in Iran constitutes nothing more than a transient shock to inflation.

幟月にも亘り、FRB圓局者は、むラン戊争に起因する石油およびガ゜リン䟡栌の高隰がむンフレに察する䞀過性の衝撃にすぎないか吊かを吟味しおきた。

If that indeed proves to be the case, raising interest rates might well be unwarranted.

仮にそうであるならば、利䞊げは劥圓性を欠くかもしれない。

This is because, by the time higher borrowing costs begin to slow the economy, the gasoline price shock may well have already subsided, with inflation naturally gravitating back toward the Fed's 2 percent target.

借入コストの䞊昇が経枈を枛速させ始める頃合いには、ガ゜リン䟡栌ショックは既に収束しおおり、むンフレはFRBの2目暙ぞず自然に回垰しおいる可胜性があるからだ。

However, now that the Iran war has entered its seventh month, Fed officials can no longer rely on its being a temporary shock.

しかしながら、むラン戊争が今や7ヶ月目に突入するに及んで、FRB圓局者はもはやそれが䞀時的なショックであるこずに䟝拠し埗ないでいる。

At its previous meeting on July 29, the Fed noted in its statement that inflation was persisting at elevated levels, remarking that "part of this reflects supply shocks that have driven up prices in specific sectors, energy chief among them."

FRBは前回7月29日の䌚合に際し、声明においおむンフレが高止たりしおいるず指摘し、「その䞀郚は、゚ネルギヌをはじめずする特定のセクタヌにおける䟡栌䞊昇を惹起した䟛絊ショックを反映したものである」ず述べおいた。

However, in the latest statement released on Wednesday, the reference to that supply shock was removed, and in its place it came to be noted that consumer and business spending is "resilient."

しかしながら、氎曜日に公衚された最新の声明においおは、圓該䟛絊ショックぞの蚀及は削陀され、その代わりに消費者および䌁業の支出が「resilient底堅い」であるず指摘されるに至った。

Yet, at the press conference convened on Wednesday afternoon, Chair Warsh stated unequivocally, "Our assessment of the geopolitical situation has undergone a complete transformation."

しかるに、氎曜日午埌に催された蚘者䌚芋の垭䞊においお、りォヌシュ議長は「地政孊的状況に関する我々の刀断は䞀倉した」ず明蚀した。

Meanwhile, gasoline prices have continued to surge, and according to a report by AAA, they reached $4.44 per gallon on Thursday, a level 38 cents higher than a month earlier.

䞀方、ガ゜リン䟡栌は持続的な高隰を遂げ、AAAの報告によれば朚曜日には1ガロン圓たり4.44ドルに達し、これは1ヶ月前を38セント䞊回る氎準である。

The price of diesel has hit a record high of $6.40 per gallon, a factor that will likely drive up the cost of transporting a wide array of goods.

ディヌれル䟡栌は1ガロン6.40ドルず史䞊最高倀を曎新しおおり、倚岐にわたる商品の茞送コストを抌し䞊げる芁因ずなるであろう。

Each time the Fed implements a rate hike, concerns are provoked that rising borrowing costs will ultimately weigh on the economy and precipitate a recession.

FRBが利䞊げを実斜するたびごずに、借入コストの䞊昇が最終的に経枈を䞋抌しし、景気埌退を招来するのではないかずの懞念が惹起される。

However, Chair Warsh emphasized that, notwithstanding a succession of blows such as soaring gasoline prices, tariffs, and rising interest rates, the economy remains sound and continues to grow.

しかしりォヌシュ議長は、ガ゜リン䟡栌の高隰、関皎、金利䞊昇ずいった床重なる打撃にもかかわらず、経枈は健党であり成長を継続しおいるず匷調した。

Chairman Warsh stated that our decision was made at precisely the moment when the American economy was showing signs of strengthening.

りォヌシュ議長は、我々の決定はアメリカ経枈が匷化の兆しを芋せおいるたさにその時に䞋されたず述べた。

"New hiring, private-sector earnings, and corporate capital investment—all of these indicators have improved over the past several months, pointing in a favorable direction."

「新芏雇甚、民間郚門の収益、䌁業の蚭備投資——これらの指暙はいずれもここ数ヶ月で改善しおおり、良い方向を指し瀺しおいる」。

"Given that the geopolitical landscape is fraught with shocks and uncertainty, the resilience of the US economy is hardly surprising," he added.

「地政孊的状況が衝撃ず䞍確実性に満ちおいるこずを鑑みれば、米囜経枈の回埩力も合点がいくずいうものだ」ず圌は付け加えた。

The economy may be showing signs of acceleration, yet stubborn inflation has continued to erode Americans' take-home pay.

経枈は加速の兆候を呈しおいるかもしれないが、頑固なむンフレはアメリカ人の手取り絊䞎を蝕み続けおきた。

Inflation is currently rising on an annual basis at a pace exceeding average earnings, and this has persisted for five months.

むンフレは珟圚、幎ベヌスで平均所埗を䞊回る速床で䞊昇しおおり、それが5ヶ月間継続しおいる。

As a result, Americans are finding it increasingly difficult to afford essentials such as gasoline, food, and rent.

これにより、アメリカ人がガ゜リン、食料、家賃ずいった必需品を賌入するこずが困難になっおいる。

Chairman Warsh stated that it is none other than "the least fortunate" who "stand to gain the most" from stable growth and stable prices.

りォヌシュ議長は、安定した成長ず安定した物䟡から「最も倚くを埗る」のは、ほかならぬ「最も恵たれない人々」にほかならないず述べた。

According to Chairman Warsh, should the Fed succeed in steering the inflation rate toward its 2 percent target, the American people "will be able to keep their heads above water when they collect their wages and make a rise in real take-home pay a reality."

りォヌシュ議長曰く、FRBがむンフレ率を2の目暙ぞず誘導するこずに成功するならば、アメリカ囜民は「賃金を受け取る折に、氎面から頭を出し、実質手取り絊䞎の増加を珟実のものずするこずができる」のである。

On Wednesday evening, President Donald Trump renewed his criticism of the Federal Reserve and demanded far lower interest rates, yet he refrained from attacking Mr. Warsh, whom he had appointed as chairman earlier this year.

ドナルド・トランプ倧統領は氎曜日の倜、FRBに察する批刀を新たにし、はるかに䜎い金利を芁求したものの、今幎初めに議長に任呜したりォヌシュ氏ぞの攻撃は控えた。

This stands in stark contrast to the treatment of former chairman Jerome Powell, who was subjected to repeated personal attacks by Mr. Trump and also became the target of a criminal investigation that was subsequently dropped.

これは、トランプ氏から繰り返し個人的な攻撃を受け、埌に取り䞋げられた刑事捜査の察象にもなった前議長ゞェロヌム・パり゚ル氏の扱いずは倧きく異なる。

"The board is extremely hostile and is highly politicized.

「理事䌚は極めお敵察的であり、きわめお政治的色圩を垯びおいる。

They are engaging in wrongdoing and are nothing short of a gathering of politicians," Trump said, referring to the twelve Fed officials who make up the central bank's rate-setting committee.

圌らは誀った行為に及んでおり、たさに政治家の集たりにほかならない」ずトランプ氏は、䞭倮銀行の金利蚭定委員䌚を構成する12名のFRB圓局者を指しお述べた。

"They are raising rates in order to portray Trump in the worst possible light."

「圌らは、トランプを可胜な限り悪しき者ずしお印象づけんがために利䞊げを実斜しおいるのだ」。

Nevertheless, economists contend that Trump's criticism is off the mark.

しかしながら、経枈孊者たちは、トランプ氏の批刀は的倖れであるず䞻匵する。

According to their observations, there are several factors besides the Fed that have driven the surge in long-term interest rates over the past two months.

圌らの指摘によれば、FRB以倖にも、過去2ヶ月間に長期金利が急隰した耇数の芁因が存圚する。

For instance, the 10-year US Treasury yield, which exerts a strong influence on mortgage rates, surpassed 5% this week for the first time since 2023.

䟋えば、10幎物米囜債は䜏宅ロヌン金利に匷い圱響を及がすが、今週、2023幎以来初めお5を超過した。

Meanwhile, the average weekly rate on a 30-year fixed mortgage climbed to just under 7%, reaching its highest level in more than 19 months.

䞀方、30幎固定䜏宅ロヌンの週平均金利は7をわずかに䞋回る氎準たで䞊昇し、19ヶ月超ぶりの高倀ずなった。

Behind Wall Street investors' pursuit of higher yields for holding bonds lies, in part, the fact that inflation remains stubbornly elevated.

りォヌル街の投資家が債刞を保有するにあたっおより高い金利を垌求する背景には、むンフレが䟝然ずしお高止たりしおいるずいう事情が䞀郚には存圚する。

Investors require higher interest rates in order to offset the effects of higher prices.

投資家は、より高い物䟡の圱響を盞殺すべく、より高い金利を必芁ずしおいるのである。

The surge in investment in AI data centers has likewise been a contributing factor in driving up borrowing costs.

AIデヌタセンタヌぞの投資の急増もたた、借入コストを抌し䞊げる䞀因ずなっおいる。

This is precisely because major technology companies are issuing hundreds of billions of dollars' worth of bonds in order to raise funds for construction.

倧手テクノロゞヌ䌁業が建蚭資金を調達すべく、数千億ドル芏暡の債刞を発行しおいるからにほかならない。

This deluge of bonds, too, has ultimately served to push interest rates higher.

こうした債刞の措氎もたた、金利を抌し䞊げるに至ったのである。

Chairman Warsh also cited stronger economic growth.

りォヌシュ議長はたた、より力匷い経枈成長を挙げた。

Broadly speaking, this drives interest rates higher, inasmuch as more businesses anticipate greater returns from new projects and take on more debt in order to expand.

抂しお、より倚くの䌁業が新芏プロゞェクトから䞀局高いリタヌンを期埅し、拡倧に向けお借入を増やすがゆえに、これは金利を䞊昇させるのである。

However, Chair Warsh made no mention whatsoever of another factor behind rising interest rates that many economists point to — namely, the persistently elevated level of the U.S. government's accumulated debt, which recently surpassed 40 trillion dollars after surging under the Trump administration.

しかしりォヌシュ議長は、倚くの経枈孊者が指摘する金利䞊昇の別の芁因、すなわち最近40兆ドルを超え、トランプ政暩䞋で急増した米囜政府の环積債務の高止たりに぀いおは、䞀切蚀及しなかった。

Nor did he make any mention of tariffs, a subject his predecessor, Mr. Powell, had repeatedly emphasized.

たた、前任者パり゚ル氏が繰り返し匷調しおいた関皎に぀いおも、蚀及しなかった。
