Markets continue to wrestle with a tug of war between risk appetite and the occasional flare-up of geopolitical uncertainty. As August comes to a close, the signals remain mixed, though the underlying tone leans toward “risk-on.” Despite the turbulence that global politics provides—particularly under the Trump administration, where headlines arrive as quickly as they are resolved—investors appear increasingly willing to test the waters and lean into risk exposure. The willingness to do so, even cautiously, says a lot about the broader sentiment driving flows across currencies, commodities, and bonds.

Sentiment and the Safe Haven Trade

The VIX, often dubbed the “fear index,” sat at 15.36 to end the month. That level is not alarming, but it does suggest a certain underlying complacency in markets, one that contrasts with the occasional shocks seen in headlines. For a deeper dive into the psychology of sentiment, I’ve written more extensively on this here: Mastering Market Sentiment.

Perhaps the most telling indicator of stress—or the lack thereof—is the gold-to-oil ratio. In August, the ratio climbed to an extraordinary 53.87. To put this in perspective, one ounce of gold now buys nearly 54 barrels of oil. Historically, the normal band sits between 10 and 30. When the ratio stretches this far, it reflects two things happening simultaneously: oil demand weakening and gold becoming the go-to safe haven. Investors are willing to pay up for protection, while crude struggles under the weight of sluggish consumption. The last time we saw extremes like this, the pendulum eventually swung back toward equilibrium. That suggests gold may be overvalued while oil is undervalued—at least until stress in the system clears. For those wanting to explore this dynamic in depth, I’ve compiled a full guide here: The Gold-to-Oil Ratio.

Equities Versus Gold

Despite elevated stock prices, gold has managed to outperform several key equity benchmarks. In the U.S., the S&P 500-to-gold ratio stands at 1.87, underscoring that gold has gained ground even as equities continue to push higher. Across Europe, the story is similar. The DAX-to-gold ratio at 8.10 sits around average levels, while France’s CAC 40 looks notably weaker relative to gold at 2.61, well below its typical 4–5 range. The FTSE 100 compares slightly better at 3.60, but the message remains consistent: gold is strong relative to stocks, a reflection of investor caution embedded beneath the surface optimism.

Japan provides another data point, with the Nikkei 225-to-gold ratio at just 0.08, toward the lower end of historical norms. That underscores not only Japan’s entrenched deflationary pressures but also the extraordinary weight of gold as a safe-haven benchmark.

Currency Strengths and Weaknesses

Using gold as the universal yardstick reveals where currencies truly stand. The U.S. dollar, for all its dominance in trade and finance, ended August as the weakest currency against gold. That caps a year-to-date performance where the dollar remains at the bottom of the pack. Across three and six-month windows, the story is the same: weakness persists, even as Treasury yields remain elevated compared to most peers. The 10-year U.S. yield sits among the highest globally, behind only the U.K. and Australia, but that has not been enough to attract steady inflows. Risk appetite is tilting elsewhere.

The euro tells a different story. In August, the euro was the second strongest performer, trailing only the yen. Over three months, it held that same rank, while year-to-date and six-month measures place it at the very top. This strength comes despite the eurozone’s chronically low interest rates and yields. German bunds remain among the lowest-yielding sovereigns outside of Japan, a reflection of cultural conservatism in debt markets. Still, the currency’s resilience signals confidence in the eurozone, even when textbook “risk-on” theory should favor higher-yielding currencies.

Sterling carved out a respectable position of its own. Against gold, the pound was the third-strongest performer in August and held a similar standing year-to-date. Over three months it slipped slightly to the fourth spot, though it remains firmly in the top tier. Its strength is backed by the highest 10-year yields in the developed world and central bank rates that trail only the U.S.

The Japanese yen showed dramatic contrasts. It was the strongest currency in August, yet over three months it was the weakest. Over six months, it ranked second weakest, though year-to-date it recovered to fourth place. This volatility reflects the yen’s sensitivity to risk cycles and its perpetual status as the world’s lowest-yielding currency. With near-zero bond yields and negative real rates, its safe-haven premium continues to ebb and flow in step with global fear.

The commodity currencies paint a more mixed picture. The Canadian dollar was the third weakest in August and remains the second weakest currency year-to-date. Yet in shorter windows, it managed brief spurts of strength. The Australian dollar showed resilience in August, finishing as the fourth strongest currency, though its broader 2025 record keeps it among the weaker performers. Its higher yields—3rd highest after the U.K. and U.S.—do provide a tailwind, but the effect is uneven. New Zealand’s dollar had one of the toughest months, ranking as the second weakest in August, and it has been volatile across different timeframes, bouncing between strong and weak rankings.

The Swiss franc deserves mention for its consistency. In August, it ranked as the fourth strongest, and across three and six-month horizons it has remained near the top, even if year-to-date it still trails. Paired with negative rates, the franc’s performance underscores its ongoing appeal as a safe haven, though it lacks the sharp, headline-driven swings of the yen.

Reading the Curve: What August 2025 Tells Us About the U.S. Economy

Every bond market enthusiast knows the yield curve is more than just a line on a chart—it’s a story about confidence, fear, and the price of time. The August 2025 U.S. Treasury yield curve tells us a story worth paying attention to.

At first glance, the curve looks almost textbook: a smooth, upward slope from the 2-year note hovering around 3.6% to the 30-year bond just shy of 5%. This is what economists call a “normal” yield curve. It’s the bond market’s way of saying, “We expect growth, we expect inflation to stay manageable, and we’re not staring down a recession in the immediate future.”

That may sound ordinary, but it’s striking when you remember where we’ve come from. Only a few years ago, the U.S. yield curve was inverted—short-term yields higher than long-term ones—a reliable red flag that recession risks were building. Fast forward to mid-2025, and the inversion has given way to something far more familiar: investors asking for a bigger premium the further into the future they lend.

What does it mean in practice? Short-term rates reflect the Federal Reserve’s stance: policy is still restrictive, keeping yields in the mid-3% range. Further out, in the 5-to-10-year space, yields climb gradually above 4%, reflecting cautious optimism about the economy’s staying power. And at the long end, 30-year Treasuries demand nearly 5%. That’s the market’s way of saying: “We believe growth will hold, but inflation and debt risks in the decades ahead are too big to ignore.”

The curve, then, is a quiet reassurance. After years of volatility and fear, the bond market is showing us a picture of stability—but not complacency. Investors are still hedging against the unknown, and the government’s long-term borrowing costs are a reminder that time, like money, never comes cheap.
