Today Markets Analysis: Global bond markets remain highly sensitive to inflation, central-bank expectations and energy prices. Brazilian 10-year yields have eased as softer inflation strengthens expectations for further monetary easing, while UK and US government bond yields remain elevated as markets reassess the outlook for inflation and interest rates.

Brazilian 10-Year Yield Falls on Rate-Cut Bets

Brazil’s 10-year government bond yield fell to around 14.14% in September, a three-month low, following softer-than-expected inflation data.

Brazil’s annual inflation rate eased to 4.22% in August 2026, from 4.44% in July and slightly below the 4.27% forecast. Inflation has therefore moved further inside the central bank’s 1.50%–4.50% target range, strengthening expectations that the Banco Central do Brasil could reduce the Selic rate by another 25 basis points at next week’s Copom meeting.

The decline in bond yields reflects the growing possibility of monetary easing, although Brazil’s still-high domestic interest rates continue to provide significant carry support for local assets.

Political developments are also increasingly influencing market expectations. Recent polling has shown Flávio Bolsonaro gaining ground in the presidential race, with markets generally viewing the Bolsonaro camp as more fiscally restrictive. At the same time, elevated borrowing costs and relatively weak business activity continue to weigh on Brazil’s economic outlook.

Institutional tensions have added another layer of uncertainty, with an intensifying dispute involving Supreme Court justices Alexandre de Moraes and André Mendonça contributing to concerns surrounding Brazil’s political and institutional environment.

UK Gilt Yields Ease but Remain Near Multi-Decade Highs

The UK 10-year gilt yield dipped toward 5.3% as the recent energy-price rally paused and investors assessed economic data ahead of next week’s monetary-policy meetings in both the UK and US.

Despite the decline, yields remain close to 19-year highs, while the 30-year gilt yield remains near 6%, a level last seen in 1998.

UK economic activity has provided some support for yields. GDP increased 0.4% month-on-month in July, exceeding expectations, while growth over the three months to July also remained at 0.4%.

Markets currently expect the Bank of England to leave interest rates unchanged next week. Governor Andrew Bailey has indicated that future policy decisions will depend heavily on incoming economic and geopolitical developments, pushing back against expectations that another immediate rate increase is inevitable.

However, inflation risks remain significant. Elevated oil prices continue to create concerns around renewed price pressures, with markets pricing substantial additional tightening through mid-2027.

US Treasury Yields Remain Elevated

The US 10-year Treasury yield was around 4.92% on Friday, slightly below Thursday’s level but still close to its highest levels since 2023.

The market continues to focus heavily on inflation. US core CPI increased 0.3% month-on-month, accelerating from 0.2% in July and exceeding the 0.2% forecast. Annual core inflation nevertheless slowed to 2.4%, while headline CPI increased 0.4% month-on-month, leaving the annual rate at 3.4%.

The stronger monthly core reading materially changed interest-rate expectations. The probability of a Federal Reserve rate increase next week rose to approximately 90%, compared with around 70% before the inflation release.

The Treasury market also absorbed another buyback operation, although demand was weaker than expected. The US government repurchased $5.2 billion of bonds against a $6 billion maximum, while approximately $10.5 billion of securities had been offered.

Today Markets View

Bond markets are increasingly being driven by the interaction between energy prices, inflation and central-bank policy. Brazil represents a contrasting story, with easing inflation creating room for lower rates and supporting a decline in long-term yields.

The UK and US remain more complicated. Persistent energy-price pressures and resilient economic data are keeping inflation expectations elevated, limiting the scope for near-term monetary easing and maintaining upward pressure on longer-dated government bond yields.

“The direction of global bond markets is increasingly being determined by whether energy-driven inflation proves temporary or becomes embedded. Brazil is gaining room to ease as inflation moves deeper into target, while the UK and US remain constrained by elevated price pressures and tighter monetary-policy expectations.”
