Summary

Joseph Wang reviews the week's central bank and market developments. The Bank of Japan hiked but disappointed markets and left the yen weak, the Bank of England adjusted QT to be less aggressive, French OAT spreads widened on fiscal and political concerns, and the US is unlikely to face a sovereign debt crisis because the Fed can always buy Treasuries. He also flags Middle East geopolitics and the US midterms as key drivers for markets and the AI trade.

  • BOJ hiked to 1.25% but two dissents signaled slower tightening; yen weakened.
  • Bank of England kept rates unchanged but tweaked QT to sell only to the government.
  • French OAT spreads over Bunds widened to about 100bp, highest in 14 years.
  • US sovereign debt crisis seen as unlikely due to Fed backstop.
  • Middle East developments are expected to drive S&P 500, oil, and yields after September opex.
  • A potential Democratic midterm sweep could bring more AI regulation and affect the AI trade.
Ideas

Fed out-hikes BOJ, yen weakens
The BOJ hiked to 1.25%, but the decision disappointed markets because two Takichi appointees dissented, suggesting slower further tightening. Meanwhile the market expects the Fed to out-hike the BOJ, keeping the US-Japan rate differential wide and arguing for further dollar strength and yen weakness.
USD/JPY HIGH

Long JGBs better behaved despite weak yen
Although the yen remains weak, long-end JGBs have been better behaved than in the past. The weak yen had been feared to spook long-dated JGBs and, through global sovereign debt markets, long-dated Treasuries; that risk is now less acute and is a positive development.

BOE QT tweak supports gilts
The Bank of England is adjusting QT to be less aggressive and will sell gilts only to the government, giving the Treasury control over the maturity structure of debt. This reduces the BOE's role in determining duration supply to the private sector and is a more neutral, supportive stance for the gilt market.
UKGILT MED

France cannot print, OAT spreads widen
French OAT spreads over German Bunds have widened to about 100bp, the highest in 14 years, because France has a wide fiscal deficit and, unlike the US, no own printing press. It is politically difficult to cut spending or raise taxes, and upcoming elections/Le Pen add risk, so fiscal troubles manifest in wider spreads.
French OATs HIGH

French OAT spreads over German Bunds have widened to about 100bp, the highest in 14 years, because France has a wide fiscal deficit and, unlike the US, no own printing press.

BNDX HIGH

Middle East events drive S&P, oil, yields
After September opex, the market will be driven mainly by Middle East developments. A positive resolution would be extremely bullish for the S&P 500, potentially pushing it to 8,000, and send yields lower; an escalation to end the war would be bad for markets, causing oil and yields to surge.

Democrats may regulate AI buildout
A possible Democratic sweep in the midterms could bring in candidates who are warier of the AI data center buildout and more supportive of AI model regulation, which could have a big impact on the AI trade.
