The US dollar strengthened on Monday as investors prepared for major interest-rate decisions from the Federal Reserve and Bank of Japan, with surging oil prices adding a new layer of uncertainty to the global inflation outlook.
The Japanese yen, which had recently climbed close to a seven-month high, lost some momentum as markets reassessed the likely path of monetary policy in the world’s largest economies.
The timing is particularly important because central banks are attempting to determine whether inflation has eased sufficiently to allow lower borrowing costs.
The Middle East energy shock threatens to complicate that calculation.
Oil Changes Inflation Outlook
Brent crude has returned above $100 per barrel following attacks on Saudi energy infrastructure and disruption around the Strait of Hormuz.
On Monday, Brent climbed above $106 while US crude moved above $102.
If those prices persist, transportation and manufacturing costs could rise globally.
Central banks normally cannot directly control oil prices.
But they must respond if energy increases begin feeding into broader inflation expectations.
That could mean interest rates remain higher for longer than businesses and households previously expected.
Trump Wants World’s Lowest US Rates
Monetary policy is also becoming politically sensitive in Washington.
President Donald Trump said ahead of the Federal Reserve meeting that the United States should have the lowest interest rates in the world, renewing pressure for significantly cheaper borrowing.
The Federal Reserve operates independently when setting monetary policy.
Its decisions are based primarily on inflation, employment and broader economic conditions rather than presidential preferences.
The latest oil shock could therefore put the Fed in a difficult position.
Lower rates could support economic growth and borrowing.
But cutting too aggressively while energy prices are climbing risks adding further inflationary pressure.
Japan Faces Different Challenge
Japan enters the week from a different position.
The Bank of Japan has been gradually moving away from the ultra-low interest-rate environment that defined Japanese monetary policy for years.
Expectations surrounding additional tightening have helped strengthen the yen.
Currency movements matter internationally because Japan remains one of the world’s largest economies and a major source of global investment capital.
Changes in Japanese interest rates can influence bond markets and investment flows well beyond Tokyo.
Critical Week for Markets
The combination of central-bank meetings and an escalating energy crisis makes this an unusually consequential week for financial markets.
Investors will be looking beyond the headline interest-rate decisions to the language policymakers use about future moves.
If central banks signal that higher oil prices have materially changed their inflation outlook, expectations for rate cuts could be pushed further into the future.
That would affect mortgages, corporate borrowing, government debt and global investment flows.
For markets, the central question is no longer simply whether inflation was falling before the latest Middle East escalation.
It is whether the new energy shock has changed the trajectory altogether.
