Gold and Silver as Safe Haven? Volatility is Back

Investors often turn to gold and silver in times of macroeconomic uncertainty. Market participants often view these precious metals as traditional “safe haven” assets that preserve value when equities falter or inflation worries spike. In early 2026, this narrative took center stage. Both metals surged to multi-year highs amid geopolitical tensions, a soft U.S. dollar, and rising inflation expectations. However, the last week of January 2026 brought a stark reminder that even safe havens can experience intense volatility. In this post, we view this risk through the lens of liquid instruments in exchange-traded funds (ETFs).

📊 Glimpse at GLD & SLV Performance

GLD and SLV are two ETFs that track the spot price performance of gold and silver. SPDR Gold Shares (GLD) is the largest gold ETF. It is widely used to proxy gold price exposure. Similarly, iShares Silver Trust (SLV) is the premier silver ETF, reflecting broader investor positioning in silver. Over the week ending January 31, both ETFs experienced sharp swings. GLD dipped from recent highs, while SLV posted even larger percentage moves. This dip reflected silver’s historically higher volatility and tendency to amplify market sentiment shifts.

📉 Late-January ETF Safe Haven Volatility

Data from the week of January 12–18 shows how sharply these assets have been moving.

  • GLD (Gold) demonstrated an intra-week range of about ~2.35 %. Its annualized volatility of ~13 % over this week indicated relatively contained swings for gold historically—even as spot prices rose.
  • SLV (Silver) exhibited an intra-week range above ~11.5%. Its annualized volatility above ~75 % over this week underscored silver’s tendency for much larger price oscillations.

In other words, silver’s volatility, especially in extreme market episodes, can be much more than that of gold, reinforcing the idea that SLV carries greater short-term risk for traders and investors alike.

📌 Historical Risk Metrics for a Safe Haven

Longer-term risk figures support this short-term pattern.

  • Silver ETF SLV has historically shown higher volatility compared with gold ETFs, meaning silver prices tend to swing harder and more often than gold when markets shift sentiment or macro drivers change.
  • Gold ETF GLD’s lower volatility has often made it a preferred choice for risk-averse investors seeking stability.

🧠 What This Means for Investors

The late-January sell-offs and reversals — where precious metals retreated significantly after touching record highs — illustrate that safe-haven status doesn’t equate to smooth performance in every market environment. Sharp reversals driven by shifts in monetary policy expectations or risk appetite can quickly compress profits and widen losses, particularly for more volatile assets like silver.

In short, gold and silver may still play roles as portfolio diversifiers or long-term hedges — but recent prices in GLD and SLV remind us that volatility is very real, and risk metrics matter when evaluating these in a diversified portfolio.

Returns in 2025 for U.S. Stock ETFs: A Strong Year

The U.S. stock market delivered solid returns in 2025. Investors benefited from artificial intelligence enthusiasm, late-year Federal Reserve rate cuts, and strong earnings across several key industries. According to The Wall Street Journal, U.S. stock funds and ETFs returned an average of about 14.6% for the year. Consequently, 2025 marked a third consecutive year of double-digit gains. As we discussed previously, the market performed well despite heightened volatility early in the year,

At the broad market level, the S&P 500 (ticker: IVV) posted a robust 17.8% total return for the year. Large-cap technology and cyclical shares contributed most significantly, according to ETFReplay.com and Yahoo Finance. The Nasdaq-100 (ticker: QQQ) outperformed the broader market. Mega-cap tech names continued to anchor market breadth late into the year as optimism around AI deployment persisted.

Sector Leaders and Laggards

Sector ETF returns in 2025 highlighted both rotation and concentrated leadership:

  • Communication Services (XTL) was the top performer, benefiting from investments in data centers and cloud computing.
  • Technology (XLK) was among the top performers, with total return growth powered by demand for semiconductors, AI infrastructure, and software. Many XLK holdings significantly outpaced the broader market over multiple time horizons.
  • Industrials (XLI) also delivered strong returns as economic activity and capital investment improved, reflecting strength in industrial and transportation names.
  • Financials (XLF) and Healthcare (XLV) logged solid gains, as bank profitability rebounded and health care stocks rallied on earnings beats and defensive positioning.
  • Utilities (XLU) and Consumer Staples (XLP), traditionally defensive sectors, generated positive but more modest returns, with staples lagging as investors favored growth-oriented ETFs.
  • Materials (XLB) and Energy (XLE) posted marginal returns, supported by commodity demand and stable energy prices, but lacked the momentum seen in tech and cyclical sectors.
  • Consumer Discretionary (XLY) saw mixed performance, often tied to retail sentiment and macroeconomic shifts throughout the year.

Market Themes from Returns in 2025

While AI-linked ETFs — including in XLK and QQQ — powered much of the returns in 2025, concerns about valuation and potential “AI bubble” dynamics persisted. Broad macro swings — from tariff-driven drawdowns to four rate cuts by the Federal Reserve — underscored a year of notable volatility even as the market finished strong.

In summary, 2025 rewarded long-term investors with healthy total returns but also demonstrated the importance of sector diversification — as illustrated by the contrasting performance among ETFs like XLK, XLI, XLF, and defensive plays like XLU and XLP.

Using ETFs to understand recent activity in the US economy

The US economy continues to navigate a complex landscape. Recent events include fluctuating inflation, evolving labor market dynamics, and the Federal Reserve’s ongoing efforts to achieve price stability. While certain sectors have demonstrated resilience, others are showing signs of cooling, creating a mixed picture for ETF investors. And, reversing trends in globalization continues.

Stock ETFs and the US Economy

The labor market, a pillar of strength for much of the past year, is showing subtle signs of moderation. While the unemployment rate remains low, job growth has slowed, and initial jobless claims have edged up slightly. This suggests a potential cooling in demand for labor, which could eventually help to ease wage pressures and contribute to lower inflation. Investors tracking the broad equity market through passively managed ETFs like IVV (iShares Core S&P 500 ETF) have witnessed the market’s sensitivity to these economic data points and the Fed’s reactions.

Bond ETFs

The bond market, as reflected in ETFs such as AGG (iShares Core U.S. Aggregate Bond ETF), has also experienced volatility. Rising interest rates have generally led to lower bond prices. But, expectations of future rate cuts can influence yields, prices, and investor sentiment. AGG, representing a broad basket of investment-grade US bonds, serves as a benchmark for overall bond market performance and investor risk appetite in fixed income.

In times of economic uncertainty, investors often turn to lower-risk assets. BIL (SPDR Bloomberg Barclays 1-3 Month T-Bill ETF), which invests in short-term US Treasury bills, can be seen as a safe haven. Increased flows into BIL may indicate a more risk-averse sentiment among investors, reflecting concerns about the economic outlook.

US Economic Direction

Overall, the recent state of economic activity in the US presents a nuanced picture. While inflation remains a concern and the labor market is showing signs of cooling, the economy has so far avoided a sharp downturn. The performance of passively managed ETFs like IVV, AGG, and BIL offers a glimpse into how investors are interpreting and acting on these economic signals. Continued monitoring of these ETFs will be crucial in understanding the trajectory of the US economy in the months ahead.

2025 Mid-year Sector Review

Happy Independence Day from ETFMathGuy! Similar to what we posted at the halfway point of 2024, this post summarizes the mid-year sector review and ETF performance in 2025. Accordingly, we highlight some of the newest trends and identify the strongest and weakest sectors this year.

Review of the 11 Sectors of the S&P 500

Indeed, there are 11 sectors in the S&P 500, as shown below. Therefore, while some of these sectors have several ETFs tracking them, we have chosen the ETFs in parentheses due to their long-standing presence in the markets. In our analysis below, we also consider the S&P 500 Index ETF (ticker: IVV), and the tech-heavy Nasdaq ETF (ticker: QQQ).

  • Information Technology (XLK)
  • Health Care (XLV)
  • Financials (XLF)
  • Consumer Discretionary (XLY)
  • Communication Services (XTL)
  • Industrials (XLI)
  • Consumer Staples (XLP)
  • Energy (XLE)
  • Utilities (XLU)
  • Real Estate (IYR)
  • Materials (XLB)

Consequently, using this list and reinvesting dividends, our sector review reveals that some sectors had total returns that did very well in the first half of 2025. However, a couple of sectors, such as Health Care and Consumer Discretionary, lost value in the first half of 2025.

This post summarizes the mid-year sector review and ETF performance in 2025, and identify the strongest and weakest sectors this year.

Analysis and Insights from our Sector Review

Outperformers occurred in six sectors, suggesting a strong cyclical comeback. Leading the way were Industrials, Communication Services, and Technology sectors. Moreover, we see that Financials, Materials, and Utilities also outperformed the S&P 500. Our sector review is in sharp contrast to the mid-year review from 2024 when only one sector (Technology) outperformed the S&P 500. These trends appear to be due to easing tariff fears, a resilient labor market, and expectations of rate cuts. It also shows that the outperformance occurred in both the growth and value sectors of the S&P 500.

Globalization and International Stock ETFs

Globalization over the last several decades has increased the correlation between domestic and international stock ETF returns. In this post, we quantify how this relationship has recently changed, what may be contributing to this change, and what it means for ETF investors.

Correlation changing?

Correlation measures potential portfolio diversification benefits. A high correlation indicates that the prices of two assets move similarly to one another. For diversification benefits, portfolios should contain assets that do not exhibit high correlation with each other. We previously discussed the correlation between the S&P 500 and a wide variety of asset classes. Below, we show that there appears to be a recent downward trend in correlation between U.S. and international stocks.

90-day Correlation of Total Returns of International Stocks (VEA) against the S&P 500. Downward trending suggests a reduction in globalization.
90-day Correlation of Total Returns of International Stocks (VEA) against the S&P 500

Here, the short-term correlation between the total returns of the iShares Core S&P 500 ETF (ticker: IVV) and the Vanguard FTSE Developed Markets ETF (ticker: VEA) hit a recent low from its longer-term average. This reduction in correlation suggests that U.S. and international stock markets are moving more independently than in the past. Thus, there is the potential to offer enhanced diversification benefits for investors.

Tariffs and Globalization

The most likely explanation of lower correlations is the news of significant tariffs on imported goods to the U.S., and perhaps more broadly, due to different central bank policies and geopolitical factors. This new trend appears to be reversing much of the investments in globalization that led to a high correlation between domestic and international stock markets. However, since most of these investments take some time to go into effect, we shouldn’t expect a rapid shift in correlations between domestic and international stock markets. The longer and more significant the tariffs are, the greater the chance that globalization will decrease. For ETF investors, enhanced diversification from international stock market investments may offer greater risk reduction than it did previously.

Bond ETFs and Money Market Funds

One of our favorite WSJ writers this week provided a critical analysis of money market funds, which many individual investors use to hold their cash. In this post, we discuss the similarities and differences between money market funds and ETFs that invest in treasury bills.

The purpose of money market funds

One purpose of a money market fund in a taxable brokerage account is to provide a place for cash to stay after it is transferred in from an outside source, like a bank checking or savings account. It also serves as a holding place for securities after they are sold. But some investors are also using them as a safe haven to avoid sharp changes in the stock market. Unfortunately, these funds tend to charge relatively high fees compared to ETFs that provide a similar safe haven. According to this WSJ article, the average money market fund charges 0.51% in fees and yields 3.89%.

But you’re probably getting ripped off on your money-market funds—and it’s one of the biggest heists on Wall Street.

Jason Zweig, WSJ columnist, May 2, 2025

Brokerages also use money market funds as a “sweep” account for investors. So, investors can benefit from this feature by being able to write checks against these balances. However, the cost and convenience of assets in these funds, which often invest in short-term U.S. treasury bills, means investor returns underperform when compared to investing in an ETF with a similar level of risk.

Very low risk ETFs

Bond ETFs still have risks, depending on the type of bonds included in them. But some bond ETFs can provide investors with direct access to short-term treasury bills, which some would refer to as a good proxy for a risk-free rate. The list below shows several of these types of ETFs, along with their expense ratio and assets under management.

ETFTickerExpenseAssets Under Management
iShares 0-3 Month Treasury Bond ETFSGOV0.09%$45 B
SPDR Bloomberg 1-3 Month T-Bill ETFBIL0.14%$47 B
iShares Short Treasury Bond ETFSHV0.15%$22 B
Three large ETFs investing in short-term U.S. treasury bills

Although the expense ratios are all quite similar, it is clear that the return of SGOV is likely to be the highest. The figure below shows this is true and that all of these ETFs had a slow and steady investment return over the last three years.

Total returns for the last three years of short-term U.S. treasury bill ETFs were higher than the average money market fund.

So, investors willing to take the time to invest their money market funds into one of these ETFs can often earn very close to the current U.S. treasury bills yield, which in the last year was about 4.8%. Additionally, these ETF returns may be exempt from state taxes, unlike money market funds. Investors not needing the convenience of money market funds may wish to consider these ETFs as an alternative safe haven.

How ETFs responded to tariffs in the news

Recent news about U.S. tariffs has impacted ETFs representing several asset classes. This post discusses both positive and negative market effects. We close with some historical perspectives to help ETF investors make educated decisions that are best for their situation.

Broad-based ETF recent performance

To see how recent tariff news has impacted several broad-based ETFs, we considered the following list.

  1. iShares Core S&P 500 ETF (ticker: IVV)
  2. iShares Core Total US Bond (ticker: AGG)
  3. SPDR 1-3 Month T-Bill ETF (ticker: BIL)
  4. iShares Barclays Long-Term Treasury (ticker: TLT)
  5. iShares MSCI EAFE (ticker: EFA)

The first ETF on this list tracks large-cap U.S. stocks. The second one follows intermediate-term U.S. treasuries and investment-grade corporate bonds. The third and fourth ETFs in our list consist entirely of short and long-term U.S. treasuries, respectively. The fifth and last ETF is an international stock ETF composed of “…developed-market securities based in Europe, Australia and the Far East“. The image above shows the total return of these ETFs for 2025.

Stock ETFs and tariffs

The sharpest downturns in the prices of ETFs due to recent announcements on tariffs appear to be in domestic and international stocks. However, since international stocks started the year stronger, they are currently at a small loss for the year. On the contrary, domestic stocks have produced a more significant negative return so far this year.

Bond ETFs and tariffs

Bond markets are typically less volatile than the stock market. In particular, short-term treasury bills returns largely follow the federal funds rate, as shown by the ticker BIL. But intermediate and long-term bond fund prices appear to have benefitted from the selloff in stocks, likely in a “flight to safety“. While investors holding bond ETFs now benefit from higher prices, yields on the underlying bonds are decreasing. If the yields decrease significantly enough, an inverted yield curve may result, which could be a sign of an economic recession. Time will tell if the leading indications of the market foreshadow such an economic downturn.

2024 Year-end returns of broad index and sector ETFs

With 2024 officially over, it is a good time to reflect on 2024 equity ETF returns. Like our mid-year post from 2024, this post highlights the top and bottom-performing ETFs by sector. We’ve added the Nasdaq-100 ETF (ticker: QQQ) 2024 returns for comparison. We also discuss what themes likely contributed to this performance.

S&P 500 Sector Returns, S&P 500 and Nasdaq ETF total returns, 2024

Top and bottom-performing sector ETFs for 2024

As the chart above shows, communication services (ticker: XTL) was the top-performing sector ETF of 2024, with a nearly 35% return. This may be surprising, given it was the worst-performing sector ETF in the 1st half of 2024. It appears that this ETF’s exposure to artificial intelligence (AI) and data centers contributed significantly to its total return for 2024. The healthcare sector ETF (ticker: XLV) was the worst-performing sector of the S&P 500 index. Considered a more defensive sector, investors were not looking for this approach in 2024. However, lower prices in the healthcare sector, relative to other sectors in the S&P 500, may bode well for healthcare ETF investors in 2025.

The S&P 500 has another strong year in 2024

For ETF investors who selected the broad-based S&P 500 index (ticker: IVV), this was another strong year, with a total return of nearly 25%. The past two years have been the best returns for this broad-market index in the past 25 years. So, investors looking for a diversified equity ETF did well in 2023 and 2024 by investing in an S&P 500 index ETF.

2025 ETF Outlook

As we noted in previous outlooks at the start of the year, there is plenty of uncertainty going into 2025. With a new political party in the White House, and the Fed still considering the potential of future rate cuts, 2025 should be another challenging year for ETF investors.

The biggest ETF may be changing

The largest and oldest ETF is the SPDR S&P 500 ETF Trust (ticker: SPY), with $624 B in assets under management. However, two other S&P 500 ETFs are close behind. The Vanguard S&P 500 ETF (ticker: VOO) and iShares Core S&P 500 ETF (ticker: IVV) have $588 B and $582 B of assets under management. In this post, we discuss the likely change in the largest ETF, what may be contributing to it, and why it matters to investors.

The oldest ETF, SPY

The SPDR S&P 500 ETF Trust, commonly referred to as SPY, has been around the longest of any ETF. With an inception date of January 1993, SPY created an entirely new way to invest in a passive index that offered greater tax efficiency than mutual funds. As we wrote about a few years ago, the taxable gains between ETFs and mutual funds can be significant. This tax inefficiency makes no difference for Individual Retirement Accounts (IRAs). But for taxable account holders, significant tax drag is drawing investors into ETFs. Several mutual funds are converting to ETFs.

The two other S&P 500 index ETFs

ETFs from Vanguard and iShares also offer ETFs that track the S&P 500 index. This index is very popular with many investors as it diversifies across many equity sectors. But, because of its weighting by market capitalization, some companies hold more significant influence. Nevertheless, it remains a popular index for investors. And, with an expense ratio of 0.03%, these ETFs offer this exposure with very little cost. These expense ratios are in stark contrast to SPY, with its expense ratio of 0.09%. While still small, the expense ratio of SPY is 3X larger, helping VOO and IVV to grow faster than SPY.

Another driver of ETF growth

So, investors seem to be preferring lower expense ratio ETFs. VOO’s unique structure may also be contributing to its popularity. But, this benefit, which Vanguard patented, has expired in 2023. So, IVV and VOO may continue to grow at a similar rate. For individual investors, the small difference between the two ETF structures likely makes little difference in meeting their investment objectives.

Stock and bond ETFs reverse recent trends

Economic data on the rising unemployment rate and corporate missed earnings appear to have contributed to the recent reverse of the upward trend in stock ETFs. This post explores this and other recent trends by highlighting selected ETFs that passively track major stock and bond indices.

NASDAQ market correction

As this WSJ article recently highlighted, the NASDAQ (ticker: QQQ) is officially in “correction” territory now. We define a correction as when prices drop by more than 10% from a recent high. Missed expectations from major investments in Artificial Intelligence by tech leaders Microsoft and Alphabet may have contributed. Nevertheless, the S&P 500 index ETF (ticker: IVV) is still up over 12% year to date, as the chart below illustrates. While returns for these two stock ETFs are lower than their mid-year peak, they are still good relative to other markets, like bonds.

Recent trends in stock and bonds ETFs.
Stock ETFs recently started a downward trend, but bond ETFs started an upward trend.

Recent trends in Bond ETFs

Investors appear to be quickly moving away from stock ETFs and into bond ETFs. This so-called “flight to safety” is clear in the image above in the recent upward trends in bond ETFs. The intermediate-term bond ETF, iShares Core U.S. Aggregate Bond ETF(ticker: AGG), shows some of this new trend. This trend is amplified when a longer-term bond ETF, like iShares 20+ Year Treasury Bond ETF (ticker: TLT), is viewed.

What is next?

The Fed left short-term interest rates unchanged after meeting this past week. But, a rate cut is looking more likely, as inflation is down to 2.5% now, edging closer to the Fed’s target of 2%. The Fed’s next meeting is in September, so investors will be eagerly awaiting the outcome of this important meeting. In the meantime, investors may continue to invest in bond ETFs to potentially hedge any additional losses in stock ETFs.
