Patient capital is often described as if patience were free. In late 2026 it is not. Waiting now has a different price in euros, Swiss francs and dollars, and the difference is large enough to alter portfolio construction.
The European Central Bank raised its deposit facility rate to 2.5 per cent in September. The Swiss National Bank, by contrast, held its policy rate at zero in its latest assessment. At the same time, the IMF expects global growth to slow to 3.1 per cent in 2026 while inflation rises to 4.7 per cent before easing next year.
For a family office, these are not three separate macro headlines. Together they determine what cash earns, what hedging costs, how much duration a balance sheet can carry and whether illiquidity is still being paid adequately.
Cash has become a strategic position
When short rates were uniformly close to zero, holding excess cash looked like indecision. Today euro liquidity earns a visible return while Swiss-franc liquidity remains expensive in opportunity-cost terms. The same nominal cash allocation therefore represents different economic decisions depending on the base currency.
This matters for families whose assets, operating companies and future distributions do not share one currency. A portfolio reported in Swiss francs may own euro credit, US private equity and sterling property, while its tax, philanthropy and lifestyle commitments remain local. Liquidity should be mapped against those liabilities rather than treated as one undifferentiated reserve.
The first question is no longer “how much cash?” It is “cash for which obligation, in which currency, and for how long?”
Duration is no longer a single bet
The euro-area investor faces positive carry at the front end but also renewed inflation risk. The Swiss investor starts from a much lower policy rate and a currency that can strengthen when risk aversion rises. Buying duration in the two markets is therefore not the same expression of confidence.
A disciplined family office can separate three decisions that are often bundled together: the desired interest-rate exposure, the desired currency exposure and the desired credit risk. A long euro bond hedged into Swiss francs may lose much of its apparent yield advantage. An unhedged position may succeed because of the currency rather than the bond thesis. Clarity about the source of return is part of governance.
Illiquidity must earn its place again
Private markets benefited for years from low cash yields and an easy comparison against public assets. That comparison is now harder. Commitments to private equity, private credit or real assets must clear a higher hurdle once liquid euro instruments offer income and the economic outlook becomes more uneven.
The issue is not that private assets are inherently unattractive. It is that the illiquidity premium can no longer be assumed. Managers need to demonstrate sourcing advantage, operational capability and realistic exit routes. Investors need to model capital calls against a stressed liquidity calendar, not an average one.
The BIS has also highlighted liquidity preparedness for margin and collateral calls across non-bank institutions, explicitly including family offices. Leverage that appears modest in normal conditions can become a liquidity problem when collateral requirements rise at the same moment that markets gap lower.
Resilience is a portfolio objective
The IMF’s phrase “resilience under strain” is useful because it describes both the economy and the balance sheet. Growth has not disappeared, but buffers are narrower. Energy shocks, fiscal pressure, trade tensions and a reassessment of AI investment can all change correlations that looked stable in calmer periods.
Resilience does not mean holding only defensive assets. It means maintaining enough liquid, unencumbered capital to act when expected returns improve. It also means avoiding a portfolio in which every attractive opportunity depends on the same conditions: cheap refinancing, stable currencies and open exit markets.
A practical agenda for investment committees
Four questions belong on the next agenda. First, are liquidity reserves matched to actual currency liabilities? Second, does every private-market commitment still beat a liquid alternative after fees and realistic duration? Third, which assets require refinancing within three years, and at what stressed rate? Fourth, how much of reported performance comes from currency rather than security selection?
The answers may not require dramatic reallocations. They may require cleaner buckets, shorter chains of leverage and a more honest required return. Family capital has an advantage precisely because it can wait. The advantage survives only when patience is priced, funded and governed.
