Inflation was caused by the Covid stimulus of 2020, and the mountains of free money printed that year (which is why it hit the entire world - every government did the exact same thing). Last I checked, Biden wasn't president at the time...
Given that Trump's economic policies are primarily the cause of inflation in the US, not sure what your point is. He printed and gave away 8 trillion dollars when combined with his tax cuts for the wealthy and people wonder why the cost of everything went up. Corporations across the planet were the beneficiaries of corporate welfare as governments printed money to battle COVID, and then they pocketed the profits and told their employees that they couldn't afford to give them raises.
