Across Singapore, Malaysia, China, Taiwan, Indonesia and the United States, the last two years rewrote a lot.
Offshore trusts became transparent in China. Taiwan closed the deathbed gift. Singapore reset its family-office conditions. Malaysia split its provident fund into three accounts. Indonesia's index provider questioned the market itself. The US made its estate exemption permanent and then loosened its beneficial-ownership rules.
If your plan depends on any one of those rules, it is brittle. If it depends on a few ideas that do not change, it can absorb them.
The foundations of finance were built for a world where rules differ by country and change by year, which makes them a good place to stand. These are the seven we return to, each with the real change it explains. The details are in the linked posts.
The rules are the weather. The framework is the building.
1. Write the policy before the market writes it for you
The idea. An Investment Policy Statement fixes objectives and constraints in writing, separate from market opinions. The change it explains. Five market shocks in two years, from Taiwan's record 9.7% fall in April 2025 to Indonesia's 11.5% two-day drop in January 2026. The investors who did best had decided their rules beforehand.

2. Separate ability from willingness
The idea. Capacity to take risk (horizon, income, spending, other assets) and tolerance for it (what you can bear emotionally) are different. Use the lower. The change it explains. Leveraged retail positions in Taiwan, with brokerage loans reportedly up 160% in a year. Ability to bear a drawdown disappears when the loan is called.
3. Policy beats prediction
The idea. Long-run outcomes are dominated by the strategic asset allocation and by costs, not by timing calls. The change it explains. The week of 2 to 9 April 2025, when the S&P 500 fell more than 12% and then rose 9.5% in one day. A 0.8-point annual cost difference on a portfolio compounding at 6% is the difference between about US$3.4 million and US$4.1 million over 25 years, on US$1 million. Costs are certain. Timing is not.
4. Judge returns after tax and in the right place
The idea. Evaluate on an after-tax basis and put each asset where its tax treatment is most favorable. The change it explains. China's July 2026 offshore-trust rules, Taiwan's controlled-foreign-company regime, and Malaysia's foreign-income exemption that applies only to income already taxed abroad. Structures that used to save tax by deferral now need to be justified on the whole path. Read more: The border stopped protecting your income
5. Risk lives in correlation, so look through the wrapper
The idea. Portfolio risk depends on how holdings move together. Count the underlying exposures, not the number of products. The change it explains. Property and trust products in China, one company in Taiwan's index, three banks in Singapore's, seven stocks in the S&P 500, and a market-wide reclassification risk in Indonesia.

6. Match assets to liabilities, including the currency
The idea. Start from what you will need to spend, when, and in which currency. Choose assets to meet it. The change it explains. The ringgit's 9.7% rise against the dollar in 2025, the Taiwan dollar's 5% single-day jump, and the rupiah's record lows in 2026. Retirement systems from the CPF to US Social Security belong on the same balance sheet, with a discount for the fact that the promisor can change the terms.

7. Keep records, and follow the stricter rule
The idea. Professional codes of conduct in the investment industry require records that support one's work and, when two laws conflict, compliance with the stricter one. Both are good household rules. The change it explains. Singapore's penalties on nine institutions in July 2025 over source-of-wealth verification, CRS 2.0 and the Crypto-Asset Reporting Framework from 2027, and the frozen-estate problem in Malaysia. In each case, the party with the better documents moves faster. Read more: Source of wealth is the new net worth and No estate tax is not the same as no estate problem
How to use them
You do not need a finance background to use these. One page is enough:
- Objectives and constraints. What the money is for, how much risk you can and will take, and the five constraints: liquidity, time, tax, legal, unique circumstances.
- Target mix and ranges, with a rebalancing rule.
- Limits on any single name, sector, country or currency.
- A records standard: what you keep, where, for how long, and who knows.
- A review date. Once a year, in calm.
When a rule changes, the page tells you what to re-check. The question is no longer "what does this new rule mean?" but "which line on my page does it touch?"
