Weekly Update: Markets, War, Inflation, and Discipline in 2026
“These things don’t go together. You must diligently work either on your own reasoning or on things out of your control.”
Epictetus, Discourses 3.15.13
We do not need a philosophy seminar to understand that warning. We see it in markets every week. Either we operate from a disciplined framework, or we react to noise. Either we plan across investment, tax, and estate strategy in an integrated way, or we allow headlines to dictate our decisions. In a calm environment, that distinction matters. In 2026, with inflation lingering and war escalating, it becomes critical.
The March 2, 2026 J.P. Morgan Weekly Market Recap shows an economy that is steady but not settled. The House Price Index edged up 1.4% year over year in December, initial jobless claims rose modestly to 212,000, and core PPI increased 0.8% month over month in January. Housing has not cracked. Labor markets remain relatively firm. Producer inflation pressures are still present. That combination does not signal crisis, but it does not signal victory over inflation either.
Equity markets reflect that tension. Over the most recent week, the S&P 500 declined 0.42%, the Dow Jones Industrial Average fell 1.28%, the Nasdaq Composite slipped 0.94%, and the Russell 2000 dropped 1.15%. Yet year to date the picture looks different. MSCI EAFE is up more than 10% and MSCI Emerging Markets has gained nearly 15%. Leadership is rotating. Portfolios that assume permanent U.S. dominance are being tested.
Bond markets tell their own story. As of February 27, 2026, the 10-year U.S. Treasury yield sits near 3.97%and the 2-year near 3.38%. Markets are pricing in 25 to 50 basis points (that’s a quarter to half a percent) of Federal Reserve cuts this year. That expectation reflects a belief that inflation will continue to ease and growth will moderate. But expectations can change quickly, especially when geopolitical events disrupt energy markets.
One of the more important themes in the weekly recap is the U.S. dollar. After declining more than 9% last year, the dollar remains under pressure. The report suggests that the move is less about foreign investors abandoning U.S. assets and more about hedging activity and narrowing interest rate differentials. The chart of the week highlights the relationship between the dollar index and the 2-year yield differential between the U.S. and major trading partners. For investors, that matters. A softer dollar amplifies returns abroad and strengthens the case for international diversification.
If this were simply a story about rotation and currency, planning would be complex but manageable. The complication is war. The escalation of military conflict involving Iran has moved from geopolitical backdrop to market driver. Coordinated strikes on Iranian military infrastructure and leadership triggered retaliatory missile and drone attacks across the region. The conflict expanded into the Gulf, raising immediate concerns about energy supply disruptions and the security of critical shipping lanes.
The Strait of Hormuz carries roughly 20% of global oil supply. Any credible threat to that corridor transmits instantly into energy markets. Oil prices surged on initial escalation and have remained volatile as markets attempt to assess duration and severity. Even short-term disruptions can drive outsized price moves because global spare capacity is thin and supply chains are tightly interconnected. Higher oil prices do not stay confined to energy stocks. They feed directly into inflation. Gasoline prices rise. Diesel costs increase. Shipping becomes more expensive. Manufacturing margins compress. Natural gas markets in Europe and Asia have also experienced volatility as LNG flows face new uncertainty. If those pressures persist, they can slow economic growth even as they push prices higher.
That is the worst combination for central banks. If inflation expectations rise because of sustained energy shocks, the Federal Reserve may be forced to delay or reduce anticipated rate cuts. If growth slows sharply due to higher input costs, policy easing becomes more urgent. Markets attempt to price that tension in real time, which is why bond yields and equity valuations can swing sharply on headlines.
Commodity markets already reflect this reality. Oil has climbed. Gold has strengthened as a perceived safe haven. Energy equities have outperformed certain defensive sectors year to date. Investors who previously dismissed commodity exposure as unnecessary are reconsidering that stance. Inflation hedges look less theoretical when geopolitical risk becomes tangible. Markets often assume conflicts will remain contained and short lived. History suggests that even if active hostilities cool within weeks, insurance costs, shipping adjustments, and supply chain realignments can linger. Those second order effects can matter more than the initial shock.
This is precisely where discipline becomes more than a slogan. You cannot predict whether oil peaks at $85 or $110 per barrel. You cannot forecast the exact length of military engagement. You cannot control whether Congress adjusts tax policy in response to rising deficits amplified by defense spending. You can control diversification, liquidity, documentation, and planning.
Tax planning is not separate from market planning. In volatile years, capturing legitimate deductions matters more, not less. Non-cash charitable contributions remain one of the most overlooked opportunities. Many families donate significantly more in clothing, furniture, appliances, and household goods than they estimate. The difference between a $500 guess and a $3,000 documented contribution can translate into meaningful tax savings.
The rules are clear. For property donations valued at $250 or more, you must obtain a written acknowledgment from the charity describing the items and stating whether any goods or services were provided in return. If total non-cash contributions exceed five hundred dollars, Form 8283 must be completed and attached to the return. If a single item exceeds five thousand dollars in value, a qualified appraisal is generally required and Section B of Form 8283 must be properly completed.
Taking photographs of donated items documents condition and quantity. Using established valuation guides helps ensure fair market value estimates are defensible. These small habits align generosity with efficiency. In a year where portfolio returns may be pressured by geopolitical volatility, surrendering legitimate deductions is simply unnecessary.
Retirement planning requires the same forward thinking. As highlighted in “5 Tax Gotchas in Retirement” by Debra Taylor, large traditional IRA balances can create significant tax exposure during the distribution phase. Required minimum distributions begin at age 73 or 75 depending on birth year and increase as the account owner ages. In strong markets, balances rise and so do RMDs. In volatile markets, distributions are still required even if asset values fluctuate.
Layer on top of that the potential expiration of favorable tax provisions. If current marginal rates revert higher after scheduled sunsets, retirees drawing significant RMDs could face materially higher tax burdens. Estate tax exemptions, currently generous, may be reduced. War driven deficits and increased federal spending could intensify political pressure for revenue adjustments. Ignoring that possibility is not prudent planning. The widow/widower penalty compounds the issue. When one spouse dies, the surviving spouse transitions from married filing jointly to single status, often retaining most of the income but facing narrower tax brackets. Medicare IRMAA surcharges can also increase. In a volatile macro environment, failing to model that transition can create avoidable stress.
Inherited IRA rules have also changed dramatically. Most non spouse beneficiaries must withdraw inherited retirement accounts within ten years, often with annual required minimum distributions during that period. This accelerates tax recognition into a compressed timeframe, potentially pushing heirs into higher brackets during peak earning years. In an environment where inflation and geopolitical uncertainty already elevate economic risk, layering tax inefficiency on top is unnecessary. Estate planning more broadly has grown more complicated. Proposals to adjust lifetime exemptions and curtail certain planning strategies surface regularly. Families with significant assets must plan years in advance, because waiting until legislation passes often eliminates the most effective options. A static estate plan in a dynamic policy environment is not a plan at all.
Integration across investment, tax, and estate planning is not theoretical. Consider a household with substantial traditional IRA assets, international equity exposure benefiting from a weaker dollar, and meaningful charitable intent. If oil prices spike and inflation persists, RMD projections change, marginal tax brackets shift, and portfolio volatility increases. If charitable contributions are poorly documented, deductions are lost. If distribution planning is ignored, future tax burdens rise. If estate documents are outdated, heirs inherit complexity and compressed tax liabilities. Each decision interacts with the others.
Markets do not move in isolation. War influences oil. Oil influences inflation. Inflation influences rates. Rates influence bond prices and equity valuations. Currency shifts influence international returns. Tax policy responds to deficits and political realities. Planning that isolates one variable while ignoring the rest is incomplete. All the issues listed above remind us that diversification remains powerful especially amid turbulence. International markets are leading year to date. Energy has outperformed certain defensive sectors. Bond yields reflect evolving policy expectations. These are not anomalies. They are reminders that leadership rotates and assumptions expire.
Investors often look for certainty in uncertain times. It does not exist. What does exist is preparation. Stress test portfolios under higher oil scenarios. Evaluate how persistent inflation affects spending assumptions. Model RMDs under different rate environments. Capture charitable deductions meticulously. Review estate documents in light of current law and plausible changes. Resilience is built before the next headline hits. It is built when portfolios are diversified before currency shifts occur. It is built when tax strategies are executed before brackets change. It is built when estate plans are updated before exemptions are reduced. It is built when discipline overrides impulse.
The world feels unstable right now. Markets are recalibrating to shifting rate expectations, a weaker dollar, divergent equity leadership, and an escalating Middle East conflict. Oil is volatile. Gold is strong. Bonds are pricing policy uncertainty. None of that is comfortable. All of it is manageable with deliberate planning.
You cannot control whether the Strait of Hormuz remains fully open. You cannot control whether oil settles at $75 or $105 per barrel. You cannot control the precise timing of rate cuts or the outcome of tax negotiations. You can control diversification, documentation, distribution timing, and strategic foresight.
In this environment, integration is not philosophical decoration. It is practical necessity. Align your allocation with global realities. Align your tax strategy with current law and credible future scenarios. Align your estate planning with distribution rules and family objectives. Align your behavior with long term goals rather than short term headlines.
Markets will move. Wars will begin and end. Policy will shift. The disciplined investor remains focused on preparation rather than prediction. That focus is not abstract wisdom. It is the foundation of financial durability in 2026 and beyond.
