According to CoinMeta, mortgage loan rates in the United States have reached their highest level in a year, with the average 30-year mortgage rate rising by 8 basis points to 6.66%. This upward trend is related to the renewed escalation of tensions with Iran and investors' concerns about the Federal Reserve's plans to curb inflation. Government bond yields soared on Wednesday, with the yield on 30-year Treasurys reaching their highest level in nearly 20 years. Analysts say that mortgage rates are usually closely correlated with 10-year Treasury yields, so there may be upward pressure in the coming days.
