The main claim is supported by the Federal Reserve Bank of New York press release titled 'Short-Term Inflation Expectations Increase as Gas Price Growth Expectations Spike', which reports that median one-year-ahead inflation expectations increased by 0.4 percentage point to 3.4% in March from 3.0% in February. Reuters' article '短期インフレ期待上昇、ガソリン価格伸び見通し4年ぶり高水準=NY連銀調査' independently matches this, also describing a rise from 3.0% to 3.4%. This substantially supports the headline statement that New York Fed 1-year inflation expectations rose in March to roughly 3.42%/3.4%. However, the added claim that the reading was below a 3.5% forecast was not established by the New York Fed source and was not confirmed by the fetched Reuters page, so that portion remains unverified.
