Key Takeaways

• Geopolitical risk is a measurable drag, not just a headline. A widely cited Federal Reserve study finds that higher geopolitical risk foreshadows lower investment and employment, and that the damage comes from both the threat of events and the events themselves.
• 2026 broke a familiar hedge. With oil driven higher by the Iran war, the U.S. 10-year Treasury yield briefly touched about 5.34%, its highest since 2002, so bonds did not cushion stocks the way textbooks promise.
• Energy is the transmission belt. Roughly a fifth of the world’s oil normally sails through the Strait of Hormuz, which is why a regional conflict becomes a global inflation story.
• Indexes can look calm while the market underneath is not. The S&P 500 sits within a couple of percent of its August record, yet market breadth is weak.
• The practical response is structural, not tactical. Diversification, a sensible time horizon and a plan for rebalancing do more than guessing the next headline.

Every few years a news story makes investors feel that the world has changed overnight. A tanker stops moving. A central bank surprises the room. A border closes. Then your portfolio app lights up red, and the temptation to do something becomes almost physical.

This guide is about doing the right something. It explains how international affairs actually reach your investments, what the evidence says about geopolitical shocks, what has happened in 2026 so far, and how to build a portfolio that can absorb the next surprise without a panic sale. It is general information, not personalized financial advice.

How a Distant Conflict Ends Up in Your Account

Geopolitics doesn’t touch prices directly. It moves through a few well-worn channels.

1. Commodities. War and sanctions disrupt supply of oil, gas, grain and fertilizer. Prices jump, and costs ripple through transport, food and manufacturing.
2. Inflation and interest rates. Higher energy prices push inflation up, which can force central banks to raise rates or delay cuts.
3. Currencies and capital flows. Money rotates toward perceived safe havens and away from import-dependent economies.
4. Corporate planning. Executives delay investment when the outlook is murky, which is exactly the effect researchers measure.
5. Sentiment. Fear alone can reprice risk assets, even before any physical disruption shows up in the data.

The academic backbone here is the geopolitical risk index built by Fed economists Dario Caldara and Matteo Iacoviello. Their paper, published in the American Economic Review, finds that higher geopolitical risk is associated with lower investment and employment and with a greater probability of disasters and larger downside risks. Industries and firms more exposed to those risks cut investment more.

What 2026 Has Looked Like So Far

Start with the shock. Iran’s reported closure of the Strait of Hormuz in early March sent Brent crude sharply higher, as Yahoo Finance reported at the time, and Treasury yields rose on bets that inflation would run hotter. Within about a week, an AP report cited Rystad Energy estimating that more than 12 million barrels of oil equivalent per day had been taken offline.

Since then, the conflict has produced a pattern of hope and disappointment. Brent fell more than 7% in one early-August week on signals of a deal to reopen the strait, per CNBC, then rebounded as the prospects faded. By October 1, Brent was back above $100.

The knock-on effects reached everyday costs. U.S. on-highway diesel averaged $6.382 a gallon in the week of September 28, about $2.63 more than a year earlier.

Where markets stood on October 5

Figures are from Schwab’s market update and are rounded. Schwab also noted that the S&P 500 Equal Weight Index had posted its seventh straight weekly loss, a sign that gains are concentrated in a small group of large stocks.

The Hedge That Didn’t Hedge

For decades, investors assumed bonds would rise when stocks fell. A geopolitical energy shock can break that assumption, because the problem isn’t weak growth. It’s inflation, and inflation pushes bond yields up and prices down.

You can see it in 2026. The 10-year Treasury hit highs not seen since 2023 in early September, according to CNBC, and then climbed past 5.3% by October 1, a level last seen decades ago. The Federal Reserve raised rates in September to a 3.75% to 4.00% range, its first hike since 2023, and its next meeting is October 27 to 28.

The UK shows the same pattern. Its 10-year gilt yield hovered near 5.4% and the 30-year yield approached 6%, according to Trading Economics, as a global bond sell-off hit one market after another.

The lesson isn’t that bonds are broken. It’s that which kind of shock you face determines which assets protect you. A growth scare favors long-duration government bonds. An inflation scare punishes them.

How Different Assets Tend to React

On gold, remember how hard it is to time. JPMorgan was reported in March forecasting gold at $6,300 an ounce by the end of 2026. In early October it traded near $4,190. A gold gain of 7.1% in a single August week was its best weekly performance since January, which also shows how violently it can move in both directions.

Why Your Home Market Matters

Geopolitics hits countries unevenly. An oil shock is a windfall for some and a bill for others.

If most of your income, spending and savings sit in one currency and one market, a geopolitical shock that hurts that economy hits you three times. Spreading exposure across regions and currencies is the cheapest protection available.

A Practical Framework for Investors

None of this requires predicting the next headline. It requires a plan you can follow when the headline arrives.

1. Decide what job each asset does

Equities for growth. Government bonds for stability in growth scares. Real assets or inflation-linked instruments for inflation scares. Cash for liquidity. If you can’t name the job, you probably don’t understand the risk.

2. Match your horizon to your holdings

Money you need within a few years shouldn’t sit in assets that can fall sharply during a crisis. Money you won’t touch for decades can ride out volatility that would be unbearable on a shorter clock.

3. Rebalance by rule, not by mood

Set thresholds in advance, such as reviewing when an asset class drifts five percentage points from target. Rebalancing forces you to trim what has run up and add to what has fallen, which feels wrong in the moment and works over time.

4. Check your inflation sensitivity

Ask what your portfolio does if energy prices stay high for a year. Long-duration bonds, rate-sensitive stocks and thin-margin businesses tend to struggle. Companies with pricing power tend to cope better.

5. Watch the transmission, not the noise

Four numbers tell you more than most cable-news segments: oil prices, bond yields, the dollar and central-bank decisions. If they are calm, the headline is probably just a headline.

Mistakes to Avoid

• Selling after the drop. Geopolitical selloffs are often sharpest early, so panic exits tend to lock in losses.
• Treating gold or any single asset as a guarantee. Hedges are probabilities, not promises.
• Ignoring currency risk. A foreign investment can rise in local terms and still lose in yours.
• Overreacting to forecasts. Price targets and scenario headlines are guesses, as the gold example shows.

Asked & Answered

Do wars always crash the stock market?

No. Research finds that higher geopolitical risk tends to weigh on investment, employment and stock returns, but the size and duration vary widely. Markets often absorb a shock and recover if the economy underneath stays healthy.

Why did bonds fall when stocks were under pressure in 2026?

Because the shock was inflationary. Higher oil prices raised inflation expectations, which pushed yields up and bond prices down, even while equities wobbled.

Is gold a reliable geopolitical hedge?

It can help, but it is volatile and hard to time. Gold moved sharply in both directions this year, and forecasts have repeatedly missed.

How does a Strait of Hormuz disruption affect everyday costs?

Roughly a fifth of the world’s oil normally passes through the strait. When that flow is disrupted, crude, diesel and shipping costs rise, which feeds into transport, food and manufacturing prices.

What should I do with my portfolio when conflict flares?

Start with your plan, not the news. Confirm your asset allocation matches your goals and time horizon, rebalance if you’ve drifted, and avoid large moves made in a hurry. For decisions specific to your situation, talk to a qualified financial adviser.

Key Takeaways

• Rep. Marie Gluesenkamp Perez (D-WA-3), a former auto repair shop co-owner, has built a legislative record centered on right-to-repair, trades workforce development, and semiconductor manufacturing funding.
• She helped secure a $105 million federal investment for Analog Devices, including $80 million for Pacific Northwest projects, to modernize domestic semiconductor fabrication — reinforcing Washington’s “Silicon Forest” manufacturing base.
• Described as one of the House’s most centrist Democrats, she sits in the Problem Solvers Caucus, the Blue Dog Coalition, and the Congressional Hispanic Caucus, and serves on the House Appropriations Committee.
• She is seeking a third term in the 2026 midterms against Republican John Braun, the Washington State Senate minority leader.
• Her legislative approach consistently favors practical, trade-oriented policy over ideological framing — a positioning that has made her a notable swing-district data point heading into November.

From Auto Shop to Appropriations Committee

Gluesenkamp Perez co-owned an auto repair and machine shop with her husband before her 2022 upset win over Republican Joe Kent, a race she repeated and won again in 2024. That hands-on business background has directly shaped her legislative priorities: she has pushed bipartisan right-to-repair legislation for agricultural equipment, introduced the Fairness for the Trades Act to expand 529 education savings plans to cover trade-career tools, and worked to ease regulatory burdens on small businesses like the one she used to run.

The Semiconductor Funding Win

In one of her more tangible economy-facing wins, Gluesenkamp Perez — alongside Washington Senators Patty Murray and Maria Cantwell — helped secure $105 million for Analog Devices to modernize domestic chip fabrication, with $80 million specifically benefiting Pacific Northwest facilities, including an expansion in Camas. The investment targets mature-node semiconductors used in automotive, healthcare, aerospace, defense, and consumer electronics — chips that are less headline-grabbing than AI accelerators but arguably more embedded in everyday supply chains (a theme covered in our companion piece on 2026 silicon supply chain risk).

Where She Sits Politically

Caucus memberships tell their own story: Problem Solvers Caucus, Blue Dog Coalition, and Congressional Hispanic Caucus place her firmly in the House’s center-right Democratic lane. She has been publicly described as one of the chamber’s most centrist Democrats, willing to break from party lines on specific votes. Her appropriations work has focused heavily on constituent-level wins — from mobile home energy-efficiency provisions to Secure Rural Schools reauthorization — over broader ideological legislation.

2026 Midterm Context

Gluesenkamp Perez is defending her seat in Washington’s 3rd Congressional District against John Braun, the Washington State Senate’s Republican minority leader — a race widely watched as a bellwether for how centrist Democrats in competitive districts perform in the 2026 midterms.

What is Marie Gluesenkamp Perez known for in Congress?

Rep. Gluesenkamp Perez (D-WA-3) is known for centrist, trades- and small-business-focused legislation, including right-to-repair bills and a $105 million semiconductor manufacturing investment for the Pacific Northwest. She sits on the House Appropriations Committee and is seeking a third term in 2026 against Republican John Braun.

Susan Collins faces her toughest reelection yet against Troy Jackson after a chaotic Democratic candidate swap. Here’s why Maine is a genuine Senate toss-up.

Republican Sen. Susan Collins faces Democrat Troy Jackson, a former Maine Senate president, in a toss-up 2026 general election after Democrats’ original nominee, Graham Platner, was replaced through a special party nomination process. Recent polling shows Jackson with a slight edge.

For a senator who has survived six consecutive campaigns and just cast her 10,000th consecutive Senate vote, Susan Collins now faces what independent analysts are calling a genuine toss-up race — one of the clearest tests of whether Republicans can hold their Senate majority in November.

A Late, Chaotic Democratic Swap

The road to Collins’ current opponent was unusually turbulent. Maine’s Democratic field originally centered on a three-way primary between Gov. Janet Mills, oyster farmer and combat veteran Graham Platner, and former Maryland government official David Costello. Mills dropped out in April, leaving Platner as the grassroots-backed front-runner heading into the June 9 primary — a candidate whose anti-establishment profile and matched fundraising against Collins had national Democrats excited about their odds.

But Platner’s candidacy collapsed amid revelations that included past social media posts and a tattoo resembling a Nazi symbol. With the general election bearing down, the Maine Democratic Party activated an emergency special nomination process — built around county-level delegate meetings rather than a snap primary — to replace him. On July 25, that process produced Troy Jackson, a former Maine Senate president, as the party’s new standard-bearer with roughly 100 days left until Election Day.

Why the Race Is Genuinely Competitive

Despite the compressed timeline, early data suggests Jackson is not merely a placeholder candidate. A Pine Tree Poll conducted by the University of New Hampshire Survey Center showed Jackson with a three-point edge over Collins among likely general-election voters, and Fox News’ inaugural 2026 Power Rankings classify the race as a toss-up — one of roughly a dozen Senate contests that will determine which party controls the chamber.

Collins’ vulnerabilities are structural as much as political. Maine backed the Democratic presidential ticket by seven points in 2024, meaning Collins has long relied on ticket-splitting voters to survive in a state that leans against her party nationally. Democrats are also targeting her more directly than in past cycles, criticizing her comment that she doesn’t regret her 2018 vote to confirm Justice Brett Kavanaugh despite his later vote to overturn Roe v. Wade, and her continued support for Immigration and Customs Enforcement funding following a fatal shooting in Maine involving ICE agents earlier this month.

Collins, who chairs the powerful Senate Appropriations Committee, is leaning on 28 years of relationship-building with industries dependent on federal spending, along with a substantial outside-money advantage. In her campaign launch, Collins argued that “my experience, seniority and independence matter,” while Democrats have countered that “seniority without a backbone is just tenure.”

What It Means for Senate Control

Maine is one of two Senate seats Democrats are defending — or, in Collins’ case, one Republicans are defending — in a state won by the opposing party’s presidential nominee in 2024, making it a marquee Senate battleground alongside Georgia, North Carolina, and Alaska. Democrats need to net four seats nationally to reclaim the majority, and unseating Collins is widely viewed as central to that math given how few genuinely competitive Republican-held seats exist on the 2026 map.

The compressed Jackson campaign timeline is itself a variable worth watching: Collins has now defeated multiple well-funded Democratic challengers over her career, and whether Jackson can build statewide name recognition and a comparable small-dollar fundraising operation in roughly 14 weeks will likely determine whether Maine actually flips or simply stays close.
