Brent crude reaches a four-month high, pushing ten-year Treasury yields to 4.97 percent and triggering a global bond sell-off.

Brent crude oil reached 109.97 dollars per barrel on Friday. This marks a four-month high. The price jumped six percent in a single session. Weekly gains totaled nearly 13 percent. Global bond yields responded with sharp increases. The ten-year U.S. Treasury yield climbed to 4.9708 percent. This is the highest level in three years. Investors now price in a higher probability of rate hikes.

Oil supply chains face disruption in the Red Sea. The Strait of Hormuz remains a point of tension. Yemeni Houthis control the port of Mocha. This threatens Saudi oil exports. Analysts at RBC Capital Markets warn of further price increases. They predict Brent could reach 121.99 dollars. This scenario assumes a full-scale conflict resumes.

Yields climb across major markets

The thirty-year U.S. Treasury yield hit 5.3803 percent. This is a nineteen-year high. Mortgage rates rise as a direct result. The housing market faces increased pressure. Two-year yields reached 4.5835 percent. Markets assign a 70 percent probability to a Federal Reserve rate hike this month. A Treasury buyback program fell short of expectations. It raised less than the targeted 6 billion dollars.

Asian markets joined the global sell-off. Australian three-year government bond yields surged 18 basis points. They hit 5.047 percent, a fifteen-year high. Japanese ten-year yields rose 6 basis points to 2.97 percent. Wholesale inflation in Japan remains elevated. This data supports the case for an imminent Bank of Japan rate hike.

Central banks prepare for tightening

JPMorgan analysts expect eight of nine developed-market central banks to raise rates. The Federal Reserve is included in this group. The Bank of Japan and European central banks are also expected to act. Reserve banks in Australia and New Zealand are part of the forecast. The tightening will likely remain shallow for now. Risks lean toward more aggressive action. Resilient growth and sticky core inflation drive this outlook. Commodity price pressures continue to weigh on policy decisions.

Geopolitical risks drive inflation fears

Commentary from U.S. President Donald Trump suggests a prolonged conflict. He stated the war could last beyond November elections. Markets are pricing in this extended timeline. Inflation risks rise with each passing day of supply disruption. The source GN markets/inflation (en-US) notes the direct link between oil prices and policy. Financial costs for the 40 trillion dollar U.S. debt increase. The bond market rout reflects a broader shift in expectations.
