In a decisive referendum on Sunday, Swiss voters rejected a proposed constitutional amendment to cap the country's population at 10 million. The proposal, which aimed to curb immigration and preserve national identity, was defeated by a margin of 62% to 38%. Meanwhile, UK Home Office figures released this morning show net migration falling to 245,000 in the year to June, a 15% decline from the previous quarter. For a finance editor who has watched the eurozone's demographic sclerosis erode its competitiveness, the contrast is illuminating.
Switzerland's rejection is not merely a political footnote. It is a market signal. The Swiss franc weakened by 0.3% against the euro in early trading, as investors digested the implications of continued open borders. The yield on 10-year Swiss government bonds edged up 2 basis points to 0.12%, a modest but telling move. Markets, after all, dislike uncertainty. And the Swiss vote leaves the country's immigration policy in a state of suspended animation: tied to bilateral agreements with the EU, yet subject to rising domestic unease.
The UK, by contrast, has already taken its medicine. Post-Brexit controls have given Whitehall the tools to manage migration with surgical precision. The latest figures show work visas down 12%, student dependants slashed by 40%, and a sharp drop in asylum applications from safe countries. This is not a tightening of the screw; it is a recalibration of the economy's need for labour versus the public's tolerance for social strain.
Critics will point to the UK's GDP growth, stuck at 0.3% in the last quarter, and argue that migration curbs are choking off demand. They miss the point. The British economy is suffering from a capital investment drought, not a labour shortage. The real yield on 10-year gilts has risen to 0.8%, the highest in real terms since 2018, signalling that investors are demanding a premium for British risks. That is not a migration problem; it is a productivity problem rooted in underinvestment in infrastructure and skills. Importing more baristas and care workers will not fix it.
Switzerland's dilemma is worse. The Swiss National Bank holds a massive foreign exchange reserve pile of 800 billion francs, built up to prevent the franc from appreciating too much. An open-door migration policy fuels domestic demand and keeps inflation above the SNB's target of 0-2%. Yet closing the door would risk the bilateral treaties with the EU that give Swiss companies access to the single market. The referendum result kicks the can down the road again, but the road is getting shorter.
The UK has already taken that road. The Brexit referendum was the can-kicker's last resort. Now, the government has the legal framework to set immigration levels according to economic need, not political expediency. The recent falls in net migration are the first tangible proof that the system works. It is a model of control, not because it is draconian, but because it is predictable. Markets value predictability.
There is, of course, a fiscal angle. Lower immigration means slower growth in the tax base. The Office for Budget Responsibility estimates that net migration of 245,000 adds about 0.5% to GDP growth per year. That is not trivial, but it is also not catastrophic. The real threat to UK public finances is the rising burden of an ageing population, which is a function of past fertility rates, not current migration. Capping migration does not solve the pensions problem; it merely shifts the dependency ratio from foreign-born to native-born workers.
Yet the British public has spoken. In every opinion poll since 2016, a majority has supported reducing net migration. The government's job is to deliver that while minimising economic damage. The early signs are promising. The labour market remains tight, with unemployment at 3.9%, but wage growth is finally outpacing inflation. That suggests that the supply of workers is becoming better matched to demand. It is what economists call 'rebalancing'. In the City, we call it 'pricing in the new regime'.
Switzerland will have to make its own choices. The vote may yet trigger a political crisis, as the anti-immigration Swiss People's Party pushes for a tougher line. For the UK, the lesson is clear: control of borders is not an end in itself. It is a means to an end: a sustainable, competitive economy that does not rely on a never-ending conveyor belt of low-skilled labour. The gilt market may not be cheering, but it is not panicking either. And in today's world, that is a victory.
