August delivered another eventful month for global financial markets. Investors had to contend with renewed geopolitical tensions, shifting expectations for US interest rates and continued volatility in government bonds. Yet despite these challenges, risk appetite remained remarkably resilient.
US equities advanced as strong corporate earnings and continued enthusiasm for technology supported sentiment, while commodities benefited from renewed inflation and geopolitical concerns. At the same time, developments in private credit and prediction markets highlighted how the investment landscape continues to evolve beyond traditional public markets.
For investors, the picture remains nuanced. Economic resilience and corporate profitability continue to provide support for markets, but higher interest-rate expectations, geopolitical uncertainty and concerns over inflation suggest that diversification and selectivity remain important.
US Equities Advance Despite the Prospect of Higher Interest Rates
US equities extended their gains during August, supported by robust corporate earnings and continued investor enthusiasm for technology.
This resilience was notable because the backdrop was far from straightforward. Renewed conflict between the US and Iran increased geopolitical uncertainty, while movements in government-bond markets reflected changing expectations about the path of US monetary policy.
The US Treasury also expanded its long-dated bond-buyback operations during the month. Investors interpreted the move partly as a source of support for market liquidity at a time when the US faces substantial refinancing requirements.
The equity rally began to lose some momentum towards the end of August, however, as increased US-Iran military activity raised concerns about energy prices, inflation and potential disruption around the Strait of Hormuz.
These risks matter because a sustained increase in oil prices could complicate the outlook for inflation just as central banks are assessing whether price pressures have moderated sufficiently.
European equities, meanwhile, were less robust. Rising government-bond yields, renewed inflation concerns and geopolitical uncertainty weighed on sentiment.
The UK market proved comparatively resilient against several continental European indices. Its relatively greater exposure to energy companies and defensive sectors offered some protection as geopolitical risks increased.
Bond Markets Signal Renewed Interest-Rate Uncertainty
Headline movements in US Treasury yields did not fully capture the volatility experienced during August.
The 10-year US Treasury yield finished the month relatively close to where it began. Beneath that relatively modest overall move, however, there were significant fluctuations.
Yields initially declined as investors focused on softer economic data and the Treasury’s expanded bond-buyback programme. They subsequently moved higher following Federal Reserve Chair Kevin Warsh’s remarks at Jackson Hole.
Warsh did not explicitly signal that the Federal Reserve would raise interest rates at its September meeting. Nevertheless, he stressed that policymakers would need to respond if they were not confident that underlying inflation was moving sustainably back towards target.
Markets reacted quickly.
Before the speech, investors were assigning roughly a 35% probability to a quarter-percentage-point increase in September. Following Warsh’s comments, that implied probability rose to approximately 55–60%.
The episode illustrates the difficult environment confronting both central banks and investors. Monetary policymakers must balance signs of weaker economic activity against the risk that inflation remains stubbornly above target.
For markets, that means expectations for interest rates could remain highly sensitive to incoming inflation, employment and growth data.
Gold and Oil Benefit from Geopolitical and Inflation Concerns
Commodities were among the stronger-performing areas of financial markets during August.
Brent crude oil rose as renewed US-Iran tensions increased concerns surrounding energy supplies. Gold also performed particularly strongly, rising by around 10% during the month according to the commentary.
The strength of gold has been accompanied by significant central-bank demand.
Central banks purchased a net 288.9 tonnes of gold during the second quarter of 2026, according to the report. That was 62% more than during the same period a year earlier and represented the strongest second-quarter total on record, with China identified as a particularly large buyer.
Several forces may explain investors’ continued interest in gold. Geopolitical instability, concerns around inflation and questions over government debt and currency values can all increase demand for assets perceived as stores of value.
The global-market return graphic on page 7 reinforces the scale of the move. It shows gold returning 13.57% during August, while oil rose 7.32%. Among the equity markets displayed, the S&P 500 gained 2.69%, Japan’s Nikkei rose 3.08% and China’s SSE advanced 4.02%, while France’s CAC 40 declined 2.06%.
Bitcoin Joins the Search for Alternative Stores of Value
Bitcoin also had a strong month, recording its best monthly performance since late 2024.
Institutional participation through spot bitcoin exchange-traded funds continued to support activity, while investors also showed renewed interest in so-called debasement trades.
These are investments sought by some investors as potential protection against currency dilution, significant fiscal expansion or persistently high inflation.
The US Treasury’s decision to increase the maximum size of its bond-buyback operations also contributed to this narrative. Some market participants interpreted the move as supportive of greater liquidity, which contributed to short-covering across parts of the market.
Gold and bitcoin are very different assets, with very different risk profiles. Their simultaneous strength nevertheless illustrates a broader theme: concerns around fiscal sustainability, inflation and currency purchasing power continue to influence investor behaviour.
Asset-Backed Finance Attracts Growing Institutional Interest
Away from public markets, an important shift is taking place within private credit.
Institutional investors are increasingly allocating part of their private-credit exposure away from traditional corporate direct lending and towards asset-backed finance (ABF).
Direct lending typically involves lending directly to an individual business. Asset-backed finance, by contrast, involves lending secured against pools of underlying assets such as consumer loans, mortgages, trade receivables or equipment leases.
This structure can provide diversified exposure while retaining some of the floating-rate income characteristics that made private credit attractive during the recent higher-interest-rate environment. Importantly, it can also reduce dependence on the financial health of a single corporate borrower.
Why is asset-backed finance growing?
One reason is that banks have become more selective when providing asset-intensive lending.
That has created opportunities for private capital providers to step into areas previously dominated by traditional banks. Specialist investment managers may therefore be able to earn attractive returns from carefully structured transactions.
Insurers are another important source of demand.
Insurance companies frequently require predictable, long-term cash flows to match their future obligations to policyholders. This is particularly relevant in the UK, where pension schemes continue transferring liabilities to insurers through bulk-annuity transactions.
For investors, ABF can therefore provide another source of diversification within private credit.
However, diversification does not eliminate risk. Investment outcomes still depend heavily on the quality of the underlying loans, the legal protections incorporated into each transaction and the expertise of the manager responsible for underwriting and monitoring those assets.
As private markets continue to grow, understanding what sits underneath an investment structure is likely to become increasingly important.
Prediction Markets Move Towards the Financial Mainstream
Another rapidly developing area of financial markets is the emergence of prediction markets as a source of investment intelligence.
Platforms such as Kalshi and Polymarket allow participants to trade contracts based on the probability of real-world events, including elections, economic data releases and policy decisions.
Trading activity increased sharply during the first half of 2026.
The appeal is relatively straightforward: the price of a prediction-market contract can provide a real-time, crowd-sourced estimate of the probability that a particular event will occur.
That information has begun attracting serious attention from established financial institutions.
Intercontinental Exchange committed up to $2 billion to Polymarket and became the exclusive distributor of its probability data to institutional capital markets through the “Signals and Sentiment” feed launched in February 2026.
For institutional investors, the attraction may lie less in placing bets on particular outcomes and more in analysing the information embedded in prediction-market prices.
Institutional Participation Is Growing — but Challenges Remain
Institutional trading activity on Kalshi increased substantially, with volumes rising roughly 800% over six months to an annualised $178 billion according to the commentary.
Much of that institutional activity appears to come from quantitative trading and market-making firms seeking arbitrage opportunities between platforms rather than making outright directional predictions about political or economic events.
Despite increasing interest, prediction markets still face significant obstacles.
Liquidity remains relatively shallow in many individual contracts, while regulation differs considerably between jurisdictions.
In the United States, federal regulatory involvement has given event contracts greater legitimacy. The position in the UK is more complicated. The Gambling Commission generally treats these products as betting, while Financial Conduct Authority rules may become relevant when contracts have characteristics resembling financial instruments.
UK platforms are consequently developing largely within existing gambling-exchange licensing frameworks rather than under a dedicated financial-market regime.
Can Prediction Markets Be Trusted?
There is also a more fundamental issue: market integrity.
Research cited in the commentary identified more than 210,000 potentially suspicious Polymarket trades between February 2024 and February 2026. Those trades reportedly achieved a win rate of close to 70% and generated an estimated $143 million in profit.
The findings raise the possibility that prediction-market prices may occasionally reflect access to non-public information rather than simply the collective judgement of market participants.
That does not necessarily remove their usefulness.
Instead, it reinforces the importance of understanding their limitations.
For UK and European institutions, prediction markets may therefore be most valuable in the near term as an additional source of information rather than as a standalone investment market.
Probabilities derived from these platforms can potentially provide timely insight into elections, economic announcements and policy decisions. But limited liquidity, regulatory uncertainty and questions surrounding market integrity mean that those probabilities should be considered alongside other sources of analysis rather than relied upon in isolation.
What Does This Mean for Investors?
August’s market performance illustrates how financial markets can remain resilient even when the economic and geopolitical backdrop appears challenging.
US equities continued to benefit from strong corporate earnings and enthusiasm surrounding technology, despite growing expectations that interest rates could remain higher — or potentially rise further.
At the same time, the strength of gold, oil and bitcoin demonstrated the continuing influence of geopolitical risk, inflation concerns and questions around fiscal and monetary policy.
Beyond traditional markets, developments in asset-backed finance and prediction markets show how quickly the investment landscape is evolving.
Asset-backed finance is benefiting as banks become more selective and institutional investors search for diversified sources of income. Prediction markets, meanwhile, are developing from specialist trading venues into potential sources of real-time information for professional investors.
Yet each development comes with its own risks.
Higher bond yields can challenge equity valuations. Geopolitical tensions can quickly affect commodity prices and inflation. Private-credit investments depend heavily on underwriting quality and legal structures. And prediction-market probabilities can be distorted by low liquidity, regulation or informational advantages.
The result is an environment in which broad market direction tells only part of the story.
A Changing Market Rewards Diversification and Selectivity
Markets have so far demonstrated an impressive ability to absorb a combination of higher interest-rate expectations, geopolitical uncertainty and bond-market volatility.
Corporate profitability remains an important source of support, particularly in the United States, while technological innovation continues to attract capital. However, the resurgence of inflation concerns and the possibility of tighter monetary policy suggest that investors should not assume the recent environment will continue uninterrupted.
Meanwhile, strong demand for assets such as gold illustrates the value investors continue to place on diversification during periods of heightened uncertainty.
The expansion of private markets and alternative sources of market intelligence creates additional opportunities, but it also increases the importance of careful investment selection.
For long-term investors, the central message remains familiar: maintaining a well-diversified portfolio, understanding the risks behind individual investments and avoiding overreaction to short-term market developments can remain particularly valuable when economic and geopolitical uncertainty is elevated
