How To Manage The Impact From the IRAN War On Your Retirement Portfolio

It’s been an interesting month in the stock market, to say the least, following the start of the Iran War, which began on February 28, 2026.

Since the start of the conflict, the S&P 500 has declined roughly 6%, largely due to the sharp increase in oil prices. Rising oil prices can impact nearly every part of the global economy because oil affects transportation, manufacturing, shipping, and production costs for countless goods and services.

In this article, we’ll discuss:

  • Why the market declined

  • How oil prices impact the stock market

  • Why market declines are normal

  • Five strategies to handle market volatility in retirement portfolios

Why the Stock Market Dropped: Oil Prices and War

Since the start of the conflict, crude oil prices climbed from about $67 per barrel to as high as $100 per barrel, before settling around $90 per barrel.

That represents:

  • About a 33% increase from just before the conflict

  • About a 50% increase compared to oil prices over the previous six months

Sudden increases in oil prices can hurt corporate profits because companies must spend more on:

  • Transportation

  • Manufacturing

  • Shipping

  • Energy

  • Raw materials

The stock market is always forward-looking. If investors believe future corporate earnings will decline, stock prices typically fall. That’s largely what we’ve seen during this recent decline.

However, it’s important to understand that a 6% market decline is not unusual. Market pullbacks like this happen regularly.

Market Declines Are Normal

Historically, the S&P 500 declines about 15% intra-year on average, meaning that during a typical year, the market will drop at some point before recovering.

If you want to achieve the historical average stock market return of roughly 10–11% per year, you must be willing to accept volatility.

There is no way to get stock market returns without stock market risk.

For retirees or pre-retirees with portfolios that are:

  • 50–70% stocks

  • 30–50% bonds

You should still expect portfolio volatility of roughly 10–12% per year on average.

This is completely normal.

5 Smart Ways to Handle Market Volatility

When markets decline, many investors panic and sell investments. In most cases, that is the worst thing you can do.

Instead, here are five strategies to consider.

1. Consider Buying the Dip

This may sound counterintuitive, but market declines often create opportunities.

If you have:

  • Cash in the bank

  • Money market funds

  • Low-yield investments

  • Money waiting to invest

  • IRA contributions to make

  • Roth IRA contributions

  • 529 contributions

Market declines can be a good time to invest because you are buying investments at lower prices.

If markets recover, those purchases may perform very well long term.

2. Rebalance Your Portfolio

Every investor should have a target asset allocation, such as:

  • 60% stocks / 40% bonds

  • 70% stocks / 30% bonds

  • 50% stocks / 50% bonds

If markets move significantly, your allocation may drift away from your target.

For example:

  • If stocks went up a lot last year, you might now be 70% stocks instead of 60%.

  • If stocks recently dropped, you might now be 50% stocks instead of 60%.

Rebalancing means:

  • Selling what has gone up

  • Buying what has gone down

  • Returning to your target allocation

This forces you to buy low and sell high automatically.

3. Continue Automated Investing (Dollar Cost Averaging)

If you are still working and contributing to:

  • 401(k)

  • Roth IRA

  • HSA

  • IRA

You should not stop investing when markets decline.

This strategy is called dollar cost averaging.

When markets fall:

  • Your contributions buy more shares

  • You invest at lower prices

  • Long-term returns often improve

Ideally, markets would stay low while you are working and investing, and then rise later when you retire.

4. Sell Underperforming Investments

Market downturns can be a good time to review your portfolio and identify:

  • Underperforming stocks

  • Poor mutual funds

  • Speculative investments

  • High-fee funds

  • Investments that no longer fit your strategy

If an investment has underperformed for years and there is no clear reason it will recover, it may be time to sell and move into:

  • Index funds

  • Diversified ETFs

  • Lower-cost investments

  • More consistent investments

5. Consider Tax-Loss Harvesting

If you own investments in a taxable brokerage account and they are currently at a loss, you may be able to sell them and create a tax deduction.

Example:

  • You bought a fund for $20,000

  • It is now worth $16,000

  • You sell it and create a $4,000 capital loss

You can:

  • Deduct up to $3,000 per year against income

  • Use losses to offset capital gains

  • Carry forward unused losses to future years

Important: Wash Sale Rule

If you sell an investment for a loss:

  • You cannot buy the same investment for 30 days

  • Or the tax loss is disallowed

However, you can buy a similar investment, such as:

  • Sell S&P 500 fund → Buy Total Market fund

  • Sell Apple → Buy Nvidia

  • Sell Coca-Cola → Buy Pepsi

This allows you to stay invested while still capturing the tax loss.

Will the Market Recover?

No one can predict the future, but historically:

  • Wars

  • Oil shocks

  • Tariffs

  • Political events

  • Recessions

  • Pandemics

  • Interest rate increases

Have all caused temporary market declines, and markets have historically recovered over time.

Often, geopolitical events cause short-term market volatility, not long-term market declines.

Large spikes in oil prices historically do not stay elevated forever, as higher prices typically increase supply and reduce demand over time.

Final Thoughts: Don’t Overreact to Market Declines

Market volatility is normal. It is part of investing.

If you want long-term growth and returns that outpace inflation, you must accept that markets will:

  • Rise

  • Fall

  • Correct

  • Recover

  • Repeat

Instead of panicking during market declines, consider:

  1. Buying the dip

  2. Rebalancing your portfolio

  3. Continuing automatic investments

  4. Selling underperformers

  5. Tax-loss harvesting

Successful investors are not the ones who avoid volatility — they are the ones who plan for it and stay disciplined during it.

Key Takeaways

  • Market declines happen every year.

  • Oil price spikes can temporarily hurt markets.

  • The S&P 500 averages a 15% decline at some point each year.

  • Volatility is required to achieve higher returns.

  • Market downturns can create investment and tax opportunities.

  • Long-term investors should avoid emotional decisions.
