Reports that Washington and Tehran may be approaching an agreement were followed by a modest decline in US Treasury yields on Tuesday. A separate report, however, said US-Iran negotiations were continuing and no deal had yet been finalised.

The US 10-year Treasury yield fell nearly 2 basis points to 5.123%, with the initial decline driven by geopolitical reports that also sent energy prices lower. A recovery in US equities added to the downward pressure on US bond yields. West Texas Intermediate (WTI), the US crude oil benchmark, is 0.67% lower at $97.58 per barrel.
Down 0.32% at 101.66, the US Dollar Index (DXY) tracks the US currency against a basket of its peers.
September’s US Pending Home Sales recorded a change of -7.3%, weaker than the -0.5% forecast, with the slump attributed to higher mortgage rates. Next on the US economic calendar are Initial Jobless Claims on 22 October, followed by the S&P Global Flash PMIs on 23 October.
At 4.789%, the US 2-year Treasury yield remains unchanged. This maturity is the most sensitive to interest rate expectations.
An October interest rate hold by the Federal Reserve was priced into money markets. For the December meeting, however, the figure remains at 89%, according to Prime Terminal.

Financial institutions charge borrowers interest on loans and pay interest to savers and depositors. These rates are influenced by base lending rates, which central banks adjust in response to economic developments. Maintaining price stability is normally part of a central bank’s mandate; in most cases, this involves targeting core inflation of around 2%. When inflation drops below target, a central bank may reduce base lending rates to encourage lending and support economic activity. Inflation substantially above 2%, by contrast, will normally prompt an increase in base lending rates as the central bank seeks to bring it down.
By making a country more attractive to international investors seeking a home for their money, higher interest rates generally strengthen its currency.
Holding gold becomes more costly in terms of forgone returns when interest rates rise, compared with owning an interest-bearing asset or keeping cash in a bank. Higher rates therefore generally weigh on gold prices. High interest rates also tend to strengthen the US Dollar (USD). As gold is priced in dollars, a stronger US currency has the effect of reducing its price.
US banks lend to one another overnight at the Fed funds rate. Set by the Federal Reserve at its FOMC meetings, this is the headline rate widely cited in financial reporting. Although expressed as a range, such as 4.75%-5.00%, it is the upper bound, in this example 5.00%, that is quoted. The CME FedWatch tool tracks market expectations for the future Fed funds rate. These expectations influence behaviour across many financial markets as participants anticipate forthcoming Federal Reserve monetary policy decisions.
