Why I'd Hesitate to Retire on 100% U.S. Stocks - and What VXUS Changes

Concentration is the risk, not missing another U.S. bull run

A portfolio with no international exposure is not a neutral choice. For retirees, it means giving up 99% of the global market capitalization outside the US and leaning far more heavily on the U.S. than many investors realize.

Retirees do not need more excitement. They need a portfolio that can keep funding withdrawals through different market seasons. That is why VXUS matters: it tracks developed and emerging markets, excluding the United States, giving retirees exposure to a broader pool of publicly traded businesses instead of doubling down on one market.

Why this matters now

International exposure is not just a catch-up trade. Global equities are being supported by solid earnings growth and a capital spending cycle tied to AI and related infrastructure. That does not make foreign stocks automatically better than U.S. stocks, but it does suggest that non-U.S. markets are still producing their own sources of return.

A U.S.-only portfolio may have less room for error when market leadership shifts. The same backdrop that supports global stocks also carries higher concentration risk and more volatility from inflation, geopolitics, and policy uncertainty. This is not an anti-U.S. argument. It is a case for not insuring your retirement against only one set of U.S. outcomes.

What VXUS can add to a retirement portfolio

For a retiree, dropping VXUS is more than a style choice. It removes tools that can help a portfolio keep funding withdrawals when one economy or market regime weakens.

Three practical buffers

• Currency diversification. A U.S.-only stock portfolio is still, in effect, a single-currency portfolio. International stocks add foreign-currency exposure and can reduce reliance on the dollar, even if you do not try to predict its direction.
• Economic and policy diversification. A broader market footprint means your portfolio is less tied to one economy, one tax environment, and one policy regime.
• More sources of recovery. VXUS does not guarantee better returns. But it can provide return streams that are less correlated with the U.S., which matters when withdrawals happen during a weak patch.

Why retirees notice this sooner

Retirees are more exposed to sequence risk because they are selling holdings while drawing income. When withdrawals happen during a poor run, a narrower portfolio has fewer unrelated sources of recovery to lean on. That is the practical reason to add diversification before it becomes necessary.

A simple way to think about it: if your foreign holdings stop producing earnings, dividends, or currency diversification, the buffer weakens. Right now, the evidence still points to solid earnings growth in global equity markets, which supports the idea that international exposure can still do some of that work.
