Why a Weak Yen Isn’t Good News for Everyone

A weak yen means Japan’s currency buys less foreign currency. It can make Japan cheaper for overseas visitors and boost some companies’ overseas earnings in yen terms. But it also raises the yen cost of imports, putting pressure on businesses and household budgets.

Whether that sounds wonderful depends partly on which currency pays your salary.

Why tourists get more for their money

When the yen weakens against your home currency, the same holiday budget buys more yen.

Take a hypothetical example, ignoring exchange fees. At ¥120 per US dollar, a ¥12,000 hotel room costs US$100. At ¥150 per dollar, the same room costs US$80.

The room has not become cheaper in yen. Your dollars simply go further.

That can encourage spending at Japanese hotels, restaurants and shops. However, higher room rates or airfares can swallow some of the saving. A favourable exchange rate does not personally supervise your travel budget.

Visitors using pounds, Australian dollars or ringgit need to check their own currency against the yen. The dollar rate alone does not tell everyone’s story.

Why households and importers feel the squeeze

For someone earning yen and spending it locally, there is no automatic holiday discount.

Japan imports fuel, food and industrial materials. When those purchases are priced in foreign currencies, a weaker yen means Japanese buyers need more yen to pay an unchanged overseas price.

Importers then face an awkward choice: absorb the extra cost, raise customer prices or find savings elsewhere.

Those costs can reach households through groceries, transport and utility bills, although contracts, subsidies and business decisions affect how quickly prices change.

If pay rises fail to keep up with living costs, households can afford less even when their salary increases. A bigger number on the payslip is less exciting when the supermarket has also discovered ambition.

Why exporters don’t all win

An exporter receiving US dollars gets more yen when those dollars are converted at a weaker yen rate. It may also have room to lower overseas prices while protecting its yen revenue.

But revenue is only half the calculation.

Imported components and energy can become more expensive. Companies producing overseas also pay overseas costs, so stronger reported earnings in yen do not automatically mean more production or better wages in Japan.

Businesses can also use contracts to reduce the effect of currency swings, delaying or limiting the impact.

The weak yen’s impact on Japan’s economy therefore depends on who earns foreign currency, who pays foreign bills and whether business gains reach workers.

A cheap holiday and a comfortable local salary are different stories—even when they share the same exchange rate.
