Sterling, Gilt yields soar as global markets fall

Pound and U.S. dollar bills are seen in this illustration.

As the last quarter of an unremittingly dire year for world markets, stocks and bonds have cratered to new lows as central banks talk tough and debt strains mount across major economies.

The blow up in British bonds and sterling remains the epicentre of this week's storm, with global credit rating firms and the International Monetary Fund lambasting UK government tax-slashing plans as incoherent in fighting inflation and a risk to debt sustainability that lifts inequality.

Even U.S. Treasury Secretary Janet Yellen said she was monitoring developments in the UK, but she added that financial markets were still functioning well with no liquidity problems yet.

The problem is in UK government bonds, or gilts, as the pound fell anew against the dollar on the credit rating and IMF warnings.

Ten-year gilt yields have jumped 1.2 percentage points in a week and the 30 year gilt yields - typically stable due to regulatory requirements and pension or insurance fund demand - have soared above 5%, almost double what they were a month ago.

The market dislocations in UK markets can be life-changing and reveal the greater impact of rising interest rates everywhere and as the dollar soars, as well as the effects of funds' holdings of so-called risk free assets on other major bond markets.

The explosion of UK benchmark borrowing rates has already seen mortgage lenders pull products due to disruptions in the interest rate swaps market and widespread concern about liability management in pension and insurance markets.

Finance Minister Kwasi Kwarteng said that he would ask financials not to bet against the pound during a meeting with bankers on Wednesday.

With Wall Street stocks hitting a new low for the year on Tuesday, global shares fell to two-year lows on Wednesday.

The Federal Reserve might have to take rates past 4.5% in its crusade against inflation, as the yields on US 10 year Treasuries topped 4.0% for the first time since 2010, as markets wagered the Federal Reserve might have to take rates past 4.5% in its crusade against inflation.
