Traders Pile Back Into Treasury Short Positions as Bond Volatility Hits Six-Month High
After a brief short-covering rally prompted by weaker US jobs data, traders rapidly reloaded bearish positions on US government bonds in the first week of October 2026, signalling that the months-long selloff has further to run. A Bloomberg Markets Pulse survey found that more than half of 173 respondents expect 30-year Treasury yields to hit 6% before the end of the year. The 10-year yield reached levels not seen since 2007 and a gauge of bond price swings climbed to a six-month high. Bloomberg Opinion noted that US net interest payments now run at roughly $1 trillion a year, accounting for around half of what the government borrows, with the federal deficit already at approximately 6% of GDP.
Why it matters for finance, banking and treasury
Sustained Treasury market volatility at these levels has direct operational consequences for bank treasury teams: repo haircuts can widen, intraday liquidity buffers may need topping up and collateral transformation desks face increased margin calls. For fixed income and rates desks, a market where short bets keep rebuilding after every rally is a sign of structural rather than cyclical selling pressure, which demands active hedging review rather than a wait-and-see approach. US fiscal dynamics, with a $1 trillion annual interest bill, raise the longer-term question of how much further term premium can rise before it feeds back into credit spreads and funding costs across the wider financial system. Risk managers and CROs should ensure their interest rate stress scenarios now include a 6% long-bond path as a plausible, not a tail, outcome.

FSB Final AI Sound Practices Report Due This Month as Cyber Risk Named Top Threat
The Financial Stability Board is set to publish its final report on 12 sound practices for responsible AI adoption by financial institutions in October 2026, a key deliverable to the US G20 presidency. In a letter to G20 finance ministers and central bank governors dated 31 August 2026, FSB Chair warned that frontier AI models' growing autonomy and offensive cyber capabilities make cyber risk the most immediate financial stability concern linked to AI. The sound practices framework covers materiality-based risk assessment, model governance, data quality, explainability, human oversight requirements that tighten as AI autonomy grows, and third-party AI risk management. Separately, HM Treasury in the UK confirmed it is gathering evidence for decisions on designating major AI and cloud providers as Critical Third Parties under the UK CTP regime.
US Treasury Yields Hit 24-Year Highs as Global Bond Selloff Deepens
Long-end US Treasury yields surged to levels not seen since 2002 in the first week of October 2026, with the 10-year touching 5.34% and the 30-year reaching 5.7%. Traders extended short positions against US government bonds even after a brief rally triggered by weaker-than-expected jobs data. BMO Global Asset Management's Earl Davis told Bloomberg that a 30-year yield above 6% is now 'inevitable' and likely to arrive within the month. Bond market volatility climbed to a six-month high as fiscal sustainability concerns, persistent inflation and a hawkish Fed backdrop combined to keep pressure on the long end.
EU Digital Omnibus Gives Banks and Insurers 16 Extra Months to Comply With High Risk AI Rules
The EU's Digital Omnibus on AI (Regulation EU 2026/1744), which entered into force on July 27, 2026, pushed the full compliance deadline for standalone high risk AI systems in financial services, including credit scoring, insurance underwriting and fraud detection, from August 2026 to December 2027. Embedded systems received an even later deadline of August 2028. Crucially, Article 50 transparency obligations still took effect on August 2, 2026 as planned, meaning banks cannot treat the extension as a reason to pause compliance work entirely. The classification list is unchanged: systems that were designated high risk before the Omnibus remain high risk.
