What's Driving the Move

Two separate forces collided this week, forcing a repricing of the rate path across G10 central banks.

The Bessent Intervention and Treasury Buyback

Treasury Secretary Scott Bessent's buyback program for long-term government bonds pushed 10- and 30-year Treasury yields down by an estimated 8–12 bp intraday at announcement, according to Reuters. The immediate outcome was looser financial conditions — directly at odds with the Fed's current stance. Inflation expectations, measured via 5-year TIPS breakeven rates, rose noticeably in response, as markets interpreted the operation as a currency-weakening strategy and an indirect form of monetary stimulus. This dynamic puts the Fed in a difficult position: the central bank risks losing control of the long end of the curve if the Treasury continues to intervene actively.

Bessent is working against the Fed's own objective — and the market is starting to price in the consequences.

Iran Sanctions: Inflation via Oil

Trump announced crushing economic warfare against Iran on Wednesday, and Bessent confirmed that a press conference is scheduled for Monday to announce what he described as "the toughest sanctions in history." According to ForexLive/investinglive.com, the market's immediate reaction is that oil prices will remain supported — or rise further — as Iranian exports potentially collapse. This is pro-inflationary and complicates the picture for all G10 central banks that have yet to cool their respective inflation processes.

Data-Driven: A Mixed Week for Other Central Banks

Beyond the two main drivers, the week delivered an economic data picture that largely confirmed existing expectations:

  • Bank of England (BoE): UK labor market data came in weak, and CPI was in line with forecasts. Markets now price in only 27 bp of tightening toward year-end, with an 81% probability of no change at the next meeting. The "wait and see" strategy remains intact.
  • RBA (Australia): Australian jobs figures disappointed to the downside, and pricing reflects just 15 bp of tightening with an 85% probability of a pause.
  • BoC (Canada): Core inflation is hovering around target. A 97% probability of a hold — the highest hold probability in the G10 universe.
  • BoJ (Japan): Core inflation came in at 1.8% y/y in August, up from 1.6%, but still below the 2% target the BoJ formally pursues. Markets price in 35 bp and a 67% probability of a hike as early as September. Focus will now shift to whether the central bank signals a faster tightening path than consensus expects.
  • SNB (Switzerland): Almost no signal — only 5 bp priced in and a 91% probability of no change.

Market Reaction Across Asset Classes

Rates and Bonds

The long end of the US yield curve faced active downward pressure following Bessent's buyback announcement — but shorter maturities held steadier, temporarily steepening the curve. 2-year Treasury yields remain anchored near the level implied by Fed expectations, but going forward markets will listen closely to the Fed's communication on how it views the Treasury's intervention.

DXY and Currency Markets

A weaker dollar — partly driven by the debasement narrative surrounding the buyback operation — provided support for the euro and British pound intraday. EUR/USD recovered somewhat after the week's correction, while JPY is in focus with BoJ tightening priced in for September. A further BoJ hike combined with a sustained Fed pause could push USD/JPY further down toward key support levels around 143–144.

Equities

Risk-on sentiment (BTC: $77,802, F&G: 72/100) suggests that equity markets are for now absorbing inflationary pressure without panic. The Treasury's liquidity injection via the buyback program is being read in part as stimulus. The technology sector is sensitive to any further rise in inflation expectations, which would push real yields higher and compress PE multiples.

Commodities

Oil is the asset class to watch most closely. Trump's Iran rhetoric provides a clear upside risk framework for crude. If Bessent's upcoming sanctions announcement on Monday actually cuts Iranian exports materially, further pressure on Brent and WTI is likely — amplifying inflationary pressure and complicating central banks' task.

The Fed and Bessent are pulling in opposite directions — and the bond market is the battlefield.

Technical Picture

US 2-Year Treasury Yield

Technically, the 2-year is holding support around the 4.55–4.60% level, which represents the lower edge of this year's trading range. A break below this would signal that markets are pricing in a more aggressive Fed pause than consensus implies. To the upside, 4.85% is a key resistance level, coinciding with levels tested after the last FOMC meeting.

DXY (US Dollar Index)

DXY is meeting resistance in the 103.5 zone and has failed to establish itself above this level for the past two weeks. RSI on the daily chart is pointing toward overbought territory (near 60), suggesting limited further upside potential in the near term. The debasement narrative surrounding the buyback operation places a structural ceiling over USD.

Oil Price (Brent)

Geopolitical risk premium from the Iran sanctions provides a technical floor around the $78–80/barrel level for now. Markets will re-test upside resistance around $84–85/barrel if the sanctions actually reduce Iranian exports materially. A break below $76, however, would signal that markets do not believe in full sanctions enforcement.

A BoJ September hike is 67% priced in — USD/JPY is the cross with the highest bimodal risk over the next 30 days.

What to Watch

Monday, August 25

  • Bessent's press conference on Iran sanctions — this is the week's single most important event. The details of the sanctions package will directly affect oil prices and global inflation expectations. Markets are waiting for concrete language on scope and enforcement.

Fed Communication (Ongoing)

  • How does the Fed respond to the Treasury's buyback program? A hawkish response (more aggressive rhetoric) will force curve flattening and put pressure on equities. A soft response increases inflationary pressure and weakens USD.

BoJ — September Meeting

  • 67% price in a hike. If the BoJ delivers and signals further tightening, there is significant movement risk in USD/JPY and Japanese government bonds (JGBs). A disappointment, on the other hand, would trigger yen weakness.

Price Levels to Monitor

  • USD/JPY: 143.00 (support) — a break here opens the door to the 140 level
  • Brent crude: $76 (floor) / $84–85 (resistance)
  • US 2-year yield: 4.55% (support) / 4.85% (resistance)
  • DXY: 103.50 (resistance) / 101.80 (support)
  • ECB and RBNZ: Any surprising data prints from the eurozone and New Zealand next week will reprice the 40–52 bp already in the market
