What is a stealth tax and why does fiscal drag matter?

A stealth tax is a higher tax take without a headline rate rise. Fiscal drag does this when frozen thresholds pull pay into higher bands over time. You pay more tax on the same real income. It matters because it quietly reduces disposable income, which can slow spending and affect UK-focused companies.

How much worse off could a middle earner be by 2030-31?

The CPS estimates a worker on £50,000 could be about £500 a year worse off by 2030-31 due to fiscal drag from the threshold freeze. The effect varies by pay growth and allowances, but the direction is clear. More earnings fall into higher bands, raising the tax share of income.

Who benefits from the triple lock pension under this setup?

Pensioners benefit because the triple lock raises the State Pension by the highest of earnings growth, inflation, or 2.5%. That helps protect retiree incomes while workers face threshold freezes. The gap in income trends can shift spending patterns, with older households holding up better than working-age middle earners.

What does this mean for UK stocks and sectors?

We expect pressure on consumer discretionary names if real incomes slip. Essentials like staples, utilities, and telecoms can look steadier. Focus on firms with pricing power, recurring revenue, and strong balance sheets. Balance equity risk with short-duration gilts or index-linked gilts if inflation or growth uncertainty stays elevated.
